Post Title: Extreme Performance Summer Tire Category Information
Posted by: coolhandluke at 3:58 PM 4/24/2010

Current Deals for tires in the Extreme Performance Summer Category


A common item that is often discussed with performance tires is tread wear or tread life. In the post below I point out two key factors to pay attention to. The first is tread depth, which is the physical amount of tread the tire comes with new.

The second is treadwear. These numbers must be taken with a grain of salt since each manufacturer uses their own test to assign this rating. That means it is likely that some use these ratings to help market their tires. I use this rating as a reference only when comparing tires. I would not base my decision to purchase a tire solely off this rating.

carrying this info over from the Chuckwalla thread...

Although, some of the dope summer street tires that are rated as "205" and "225" on paper actually measure out wider if you look at their 'section width' specs.
Some 205's are closer to 215 width than others.

check it...
15/205
Toyo R1R = 8.5" = 215.9mm width (widest of the 205's!)
Bridgestone RE11's = 8.4" = 213.3
Dunlop Starspecs = 8.4" = 213.3
Kumho Ecsta XS = 8.4" = 213.3
Yokohama AD08 = 8.3" = 210.82
Federal 595rsr = 8.3" = 210.82
Falken Azenis RT615K = 8.2" = 208.2

Things to keep in mind:

#1- 71R does better pinched than the Rival-S (in equivalent sizes)
#2- The RS3v2 may be older but it's not irrelevant (and it wears better).
#3- The V720 didn't do badly at all. Aside from the noise, these may be a decent (and cheap) option. Still haven't had enough folks run them to know how they handle heat or track use though.

Remember the testing TR did was on a pretty heavy BMW, on stock width wheel, with a stock alignment, and with the tires at the recommended pressure per the door placard in the car. i.e. nothing was optimized.

Nearly everything evolves over time - true for living things, true for cars, and definitely true for tires. The basic process to design and build passenger car tires may not have changed all that much, but many of the components that go into making them have, and more importantly what tires are capable of doing has evolved to the point that the father of the pneumatic tire, John Boyd Dunlop, might not recognize some of them beyond still being round and black.

Nowhere is this more apparent than at the top of the street tire food chain, in the Extreme Performance Summer tire category. Over the past decade, this category has evolved from a few niche products to a full array of tires from many brands delivering dry performance and handling for the street and track that was unimaginable just a few years ago. Once focused solely on ultimate dry performance at the expense of everything else, other attributes are now evolving too, as sometimes road manners, treadwear and even wet traction are improving along with continuing gains in ultimate dry performance. In addition to watching the category's family tree flourish with an ever-growing list of new flagship products developed to entice enthusiasts and track/autocross drivers, we're also seeing product life cycles get shorter. Last year's hot performer might turn into this year's old news that then becomes updated or even replaced a year or two from now. Survival of the fittest, or fastest, as it were.

This time around we're treated to three new products in the Extreme Performance Summer category. BFGoodrich is following a path they've taken previously for their DOT Track and Competition tires that starts with an existing design and modifies it with a new compound, trading off some treadwear to gain ultimate grip and lower lap times. So, too, for the new g-Force Rival S, which comes out of the same mold as the original g-Force Rival, but rides on a new tread compound designed to come up to optimum temperature more quickly during dry autocross and sprint track use, while also improving wet traction.

Bridgestone's new tire, the Potenza RE-71R, resurrects an old product name from their performance tire heyday in the 90s. Updated with over 20 years of learning and technological advances, the Potenza RE-71R features a newly developed tread compound and a highly tuned internal construction that maximize contact with the pavement to boost performance.

Kumho was a player in the early days of the Extreme Performance Summer tire category, but has been absent for a while. They've returned with the Ecsta V720, which builds on a tread pattern already available in Asia. Tires for the North American market get a unique tread compound and internal structure tuned specifically for the way performance drivers in this part of the world use their tires.

To see how these three new players perform, the Tire Rack team conducted a Real World Road Ride and Performance Track Drive comparing them with one of last year's newest and top performers, the Hankook Ventus R-S3 (Version 2). Our evaluation used 2014 BMW F30 328i sedans fitted with new, full tread depth 245/40R18 tires mounted on 18x8.0 wheels.
What We Learned on the Test Track

Our 1/3-mile per lap test track course includes 90-degree street corners, a five-cone slalom and simulated expressway ramps. Run in both dry and wet conditions, the test track allows our team to experience the traction, responsiveness, handling and drivability normally only encountered during abrupt emergency avoidance maneuvers or competition events.

Extreme levels of dry weather performance and handling are the reasons these tires exist, and on our test track none disappointed. The Bridgestone Potenza RE-71R stood out, with quick outright speed and impressive traction in all directions - cornering, braking and especially accelerating. It also delivered amazing precision and exceptional communication to the driver. This characteristic helped all of our drivers maximize the tire's performance from the first corner, and nearly everyone clicked off very consistent lap times.

The Kumho Ecsta V720 followed close behind, providing predictable handling, good communication of its limits and very high traction level. Track performance of the BFGoodrich g-Force Rival S was a small step back from the leaders, and while still reasonably quick, didn't have the steering response, precision or clear communication to the driver of the faster tires. Right behind the Rival S was the Hankook Ventus R-S3 (Version 2). One of the top new tires the previous year, it's now pushed to fourth fastest among a relatively tight group this time around as the newer tires from Bridgestone, Kumho and BFGoodrich move the performance needle forward. In the end, there is a pecking order to track performance, but all four of these tires are very capable in the dry, and will provide better ultimate handling and quicker lap times than even the best Max Performance Summer tire.

As we watch the dry performance level of Extreme Performance Summer tires evolve and march ever-higher, we're also seeing what is essentially a nuclear arms race play out as tire brands really push the performance limits of true street tires. For the first time during our track testing we're seeing tread rubber marbles ("clag") form just off the driving line in high-load corners. During track duty these tires are sacrificing themselves as they lay down fast lap times. It's of little surprise given the fast pace of the top tires, but brings with it noticeably higher wear rate on the BFGoodrich, Bridgestone and Kumho than we've encountered in past tests of Extreme Performance Summer tires. Now one of the old guard, the Hankook's treadwear rate was visibly less than on the other three tires, and similar to what we've seen in past testing of other Extreme Performance tires.
Track Clag

Impressive dry performance isn't the only story with these tires. In the early days of the Extreme Performance Summer tire category, high wet traction was abandoned in the search for maximum dry grip, and up until recently this was still the case. We saw the initial signs of this trend changing when we first tested the Hankook Ventus R-S3 (Version 2) in 2014, which performed remarkably well in warm, wet conditions. This time around we find all four tires in the test delivering wet traction that is beginning to approach that of good Max Performance Summer tires, the traditional go-to category to find the highest levels of wet grip.

In our wet track test, the spread in lap times across all four tires was slightly less than a quarter of a second, one of the narrowest margins we've encountered across a test group. The Potenza RE-71R repeated its friendly nature found in the dry, proving easy for our drivers to maximize lap after lap. The g-Force Rival S, Ecsta V720 and Ventus R-S3 (Version 2) were close behind. Measured tests of cornering traction and ABS-assisted panic stop distances mirrored lap times with surprisingly similar results for all four tires.

It's important to note our wet test focuses on traction, and doesn't include speed and water depth to create appreciable hydroplaning. Anecdotally the limited void space and shallower molded starting tread depth of these Extreme Performance Summer tires causes hydroplaning at lower speeds and with more abrupt onset than with other summer performance tires that feature less aggressive tread patterns.
What We Learned on the Road

Our 6.0-mile loop of expressway, state highway and county roads provides a great variety of road conditions that include city and highway speeds, smooth and coarse concrete, as well as new and patched asphalt. This route allows our team to experience noise comfort, ride quality and everyday handling, just as you would during your drive to school or work.

As the category name implies, these are extreme tires designed to perform. And like most things that are this specialized there are trade-offs. The steps needed to deliver this level of handling and traction results in a sacrifice in ride and noise comfort during everyday driving. As a consequence, we found the top performing tires on the track to be rather punishing during everyday driving on the road. One can make the argument that given the focus of these tires, road manners are of little importance. But buyers should beware of what they're getting. If you drive a fairly quiet performance car, the impact on everyday comfort is sizeable. If you install these Extreme Performance Summer tires on a more modified, stiffly sprung and loud car, then it's less apparent.

All four of these tires handle very well at the light-duty levels found driving along with surrounding traffic. Steering feels direct, response is very linear, and the communication to the driver of what is going on is clear and precise.

From a noise and comfort standpoint, several of these tires stand out, and not in a positive way. The noise level of the Kumho Ecsta V720 can only be described as loud, all the time. Once speeds climb past 20mph a steady drone from its tread pattern is heard. The unsuspecting driver might think a wheel bearing is failing, as the growl can be fierce and rises and falls in direct sync with speed. Nearly as loud is the Bridgestone Potenza RE-71R. This tire also makes a constant, steady whir easily heard above the surrounding ambient noise from wind and adjacent traffic. In addition, the Potenza RE-71R emits a unique sound when it crosses tar strips, paint stripes or rolls over certain smooth pavement surfaces, almost like the sound of sticky tape being pulled off plastic. These two tires are possibly the loudest passenger car street tires we have ever tested out on the road.

Relative to the noise from the Kumho and Bridgestone tires, the BFGoodrich and Hankook tires brought welcome relief to the aural onslaught. But make no mistake, even these tires are considered loud when compared with less extreme summer performance tires. The blocky-looking tread pattern of the g-Force Rival S gets the closest of this test group to producing noise levels that approach reasonable. The Ventus R-S3 (Version 2) generates a noticeable growl, but it's much more distant than the worst offenders of the group.

Given the sporty nature of these tires, ride quality is not a high priority. Consequently, all four tires deliver rather firm rides, with the Rival S and Ventus R-S3 (Version 2) tires riding the best, and the Potenza RE-71R and Ecsta V720 tires feeling quite firm, to even somewhat harsh when encountering large, sharp impacts.
Fuel Consumption Results

Our Real World Road Ride features a relatively flat 6.0-mile loop of 65 mph expressway, 55 mph state highway and 40 mph county roads along with two stop signs and one traffic light every lap. Our team drove each tire approximately 500 miles over the course of several days. Since we wanted to compare fuel consumption results that typical drivers would experience, our drivers were instructed to maintain the flow of traffic by running at the posted speed limits and sustain the vehicle's speed using cruise control whenever possible. They did not use hypermiling techniques to influence vehicle fuel economy.

Tire Test MPG* Gallons/Year
@ 15,000 Miles % vs. Most Efficient
BFGoodrich g-Force Rival S 30.0 500.0 --
Bridgestone Potenza RE-71R 29.9 501.7 -0.33%
Hankook Ventus R-S3 (Version 2) 29.9 501.7 -0.33%
Kumho Ecsta V720 29.7 505.1 -1.01%
*Our evaluation used Race Technology DL1 data loggers to record true distance travelled.

Given their extreme traction focus, none of the tires in this test were designed with low rolling resistance as a high priority. Consequently our testing didn't show a significant difference across the group, with just 3/10ths of a mile per gallon difference between the lowest and highest observed fuel consumption. For drivers travelling 15,000 miles per year the difference from lowest to highest works out to just 5.1 gallons of premium gasoline, which at the current cost of $3.00/gallon amounts to just over $15 per year.

It's important to note our test's fuel consumption measurements follow consistent procedures designed to minimize variables that could influence the results, however they do not represent an exhaustive long-range fuel consumption study. While our procedures require the test vehicles in each convoy to run under the same prevailing conditions, the week-to-week differences in ambient temperatures, barometric pressures and wind speeds that we experience over a season of testing can influence vehicle fuel consumption and prevent the absolute mpg values of this test from being compared directly against those of others.

Larger differences in consumption between tires may indicate a difference that might be experienced on the road, while smaller differences should be considered equivalent. As they say, your mileage may vary.
Summary

If you want the highest level of traction and handling in a true street tire and are willing to give up civilized manners to get it, then an Extreme Performance Summer tire fits the bill. All four of the tires in our test deliver amazing traction and handling in dry conditions along with impressive wet grip. The newest designs offer the best outright performance, but are evolving to be much less street-friendly in the process.

Subjectively the BFGoodrich g-Force Rival S outscores the other tires by a small margin, combining strong performance with reasonable road manners. But when it comes to ultimate dry and wet performance among this group, the Bridgestone Potenza RE-71R is the top rung on the evolutionary ladder. The Kumho Ecsta V720 gives the Potenza RE-71R a run for its money by delivering impressive dry performance, but brings along road manners so extreme that it's not for the faint of heart and not well suited to daily commuter duty. The Hankook Ventus R-S3 (Version 2) holds its own against tough competition, but from an outright performance perspective it's clear that newer designs are a little faster.

Great thread!

So how does the Bridgestone RE-11 compare to the Falken RT-615K? The RE-11 has 1/32" more tread depth, but has 20 A A less on the treadwear rating than the RT-615K. Which would be a better deal in terms of longevity and stickiness? Also, the RE-11 has a 100 dollar rebate on a set of 4 from TireRack, which brings the price of a set of 205/45/16 to almost exactly the same price as a set of 205/40/16 of the RT-615K. Here's a link to the promo: http://www.tirerack.com/specialoffers/d ... omoID=B010 Which is the better tire of the two?

I don't think there has been a comprehensive review of the 615Ks yet, which along with the $100 rebate offer is why I went with RE-11s this year.



Post Title: Re: Extreme Performance Tire Information
Posted by: bluebomber at 10:17 AM 4/29/2010

Well, with the rebate, the RE-11 is only an extra 4 dollars per tire! Is the RT-615K going to last longer than the RE-11, or do you think their life will be about the same or less? I'm really leaning towards the RE-11, but the sub-10,000 mile lifespan of them (from what I have heard) kind of makes me want to go with the RT-615K in the hopes they will last longer.



Post Title: Re: Extreme Performance Tire Information
Posted by: 98spec022 at 10:26 AM 4/29/2010

I picked up my RE-11s when they were <$100 each so its a better deal for me :lol: Lifetime doesn't make much of a difference to me since they will be track/AX tires, but I won't even try speculating how long the 615Ks might last.

The 615k's were just released. Unfortunately there isn't any significant data or reviews [i:2jl9ltyi]yet[/i:2jl9ltyi]. Summer is approaching so I hope that changes very soon from a creditable source. Also, i don't recommend 205/40/16 tire size at all. For 16'' selections look for 205/45 or 214/45 tire options. No model will be offered in both and the difference between the two should not a be deciding factor on your tire purchase.

Hmm. Now I am confused. nsxtasy on H-T wrote this to me in another thread in Wheel/Tire:

Quote, originally posted by "nsxtasy on H-T" »
205/45-16 is too large for your car. You need to stick to 195/45-16 or 205/40-16. The reason is that both these sizes are close in outer diameter to your stock size of 185/60-14, as you can see:

185/60-14: 22.74" (stock)
195/45-16: 22.91" (+0.7 percent)
205/40-16: 22.46" (-1.3 percent)
205/45-16: 23.26" (+2.3 percent)

It's not just a matter of cost. Another downside is that the oversized tires may rub. They also will make your car accelerate slower, due to the added weight as well as the added diameter (they are like putting taller gears on your car). They will also throw off the accuracy of your gauges.

Stick to 195/45-16 or 205/40-16."

Why wouldn't you recommend a 40 series?

I'm guessing he's talking about stock tiny wheel civic sizes while most always use the more common integra/newer civic sizes. Or he was just having an off day...:P 205/40 is a really really short tire. Hardly any sidewall. You won't have any rubbing issues unless your car is retardedly low. So low that the other sizes would likely rub as well. 205/45 and 215/45 would be the better tire sizes

Maybe because the advice that works for ITR also works for my setup because it's the same? It shouldn't need to be said considering we're on a site for ITR. It's the same as if I had one. Now please stop following me around. You're annoying.

Thanks for the informative reply. My car has about a 2 finger gap all around. 215 series no matter the size and 50 series no matter the size all rub on my setup, so I guess I will just stick to 205/45/16 then. That's the size I have on now anyway and it works without rubbing.

So it seems like the RE-11 would be the one to get since they come in a 45 series. Does the RT-615K comes in a 45 as well? I couldn't find one on TireRack or DTD.

not really how it works. Has entirely to do with the VSS and VSS gear you have in your transmission.

The lugs and suspension have nothing to do with what size tires are the "correct" size.

Well, I had some previous sets of tires that rubbed huge holes in my fender liner, pretty much shredding it. I first had 205/50/15, which rubbed, then got new rims. I've had a set of 215/45/16, and a set of 205/50/16, and they all rubbed. Not heavily, but enough to be annoying and wear them out prematurely. 205/45/16, what I have on now, seems to be the largest I can run without rubbing. Maybe there is some combination of a 215 or a 50 series (not together) that will work, but all the combinations I've tried so far haven't.

I didn't think the RT-615K came in a 45 series, since I couldn't find it. Guess I'm going for the Bridgestone RE-11 or the Continental ExtremeContact DW, since they are the only 2 I have been looking at in a 205/45/16.

Your ride height larger dictates rubbing. Most here track there cars and do not have fender liners. In both cases it is usually recommended to roll your inner fender liner. Again, I don't recommend using a fixed tire size (like 205/45) when shopping for tires, instead a tire based on its performance...but its your car.

The 615K's (and 615/215s) were all offered in 215/45/16. That size is listed in my first post. The Continental ExtremeContact DW's are not even in the same tire category as the others I have mentioned here. Please do not discuss them in this thread as it is only for tires in the Extreme Performance Tire category.

Most of the manufacturers have their own terminology for the top-of-the-line summer tires. So, it's back to a choice between the RE-11 and the RT-615K. The Bridgestones are looking more attractive the more I learn about these kinds of tires, especially since they have the size I want. I really wish someone has a side-by-side for these two tires. I'd love to see them in a shootout and see which one comes out on top.



Post Title: Re: Extreme Performance Tire Information

Tire MFG's don't make their own tire categories. This is an established tire category for performance oriented tires. You are preaching to the choir on the review. Most (if not all) of us are awaiting a solid review on that tire. Many of us have used the 615's for years (and 215's before that).

I didn't realize there was a difference between ultra high performance and extreme, but the difference has been noted.

I do think its stupid how many categories of fast summer tires they have. Extreme, Ultra High, Maximum, blah blah blah. To someone who doesn't know about the specific models that would be extremely frustrating.

Also, X2 on the ride height thing. If you're rubbing holes in the fender liner of a Civic on 205/50s, you're way too low.

Well, I just got new tires yesterday. I ended up with the Bridgestone Potenza RE-11 in 205/45/16. I have to say, I love these tires. They are possibly the best mod I've ever done. I've never had such sticky tires before and it makes my car feel completely different, especially on freeway onramps and through turns. These were replacing a set of Yokohama ES100. The difference between the 2 is night and day! I'm sure these won't last too long, and they cost me a bundle (783 after the 100 dollar rebate), but they sure are fun for now.

I'm considering purchasing the Falken Azenis 615K's and the Khumo XS's. I'm aware of the wet performance drop on the XS's. The question is are the 615K's worth the additional $100 price tag over the XS's. I still would like to pickup a set of RE-11's but I could almost get two sets of Khumo's XS's for the price tag of one set of the RE-11's. If and when they come off their high horse price tag or offer a rebate I'l run them.

RE-11s + RAIN = 1st place


I have less than half tread left and I dont recall hydroplanning at all. Actually I could not believe the grip that I had in standing water. Some of it was most likely the surface I was on (at the Nationals site) but the tires really hooked up in the wet. Just in raw times, I even out ran a 700hp Viper with a very good driver behind the wheel.

The price is their downfall. I missed their reduced price window and now they are almost double the price of others in the same category. I can do almost do a weekend event with the savings when choosing XS's over them. I can almost do a one day event with XS savings over the 615K's. I'm working my contacts for better pricing. We'l see what I can get my hands on at a reasonable rate.

I paid 783 bucks for my tires out the door (tax, mounting, balancing, and filled with nitrogen) after the rebate, and I have to say, it was the best investment in my car I've made to date.

I haven't been looking at 15'' sizes since my K1's have plenty of life on mine. I'm getting greedy and want to run fresh tires over older 615's. The RE-11's are $162 in 16'' sizes from tire rack, which doesn't include shipping. The 615K's are $126, and the XS's are $100.

Tire prices are why I originally switched to 15''s. A friend has sold me a set of 16'' wheels for cheap which is the only reason I will have them. My choice deals more with tires being a wear item than my budget. I'm not sure what you are competing in but I hope they serve you well.

You could have a set of 15" Hoosiers for close to $800, and they'd be way better than RE-11s.

Shit, I spent $600 on R1s this year (which was a good price for them to begin with), and that made me feel pretty damn stupid, especially after finding out they're a bit narrow for my application. Assuming you have limited track experience, the $300 difference would be better spent on another event. You most likely won't see the 0.1sec/lap difference the RE-11 offers over the XS or whatever.

Also for the record, 16" wheels are the worst EVER for tire sizes and availability. Nothing sucks more than that diameter.

I have two sets of 15'' 615's that are close to their end in life. I don't mind tracking on them but I won't make a ~13hr drive on them. I'v picked up a set of 16'' wheels that need tires which is the only reason I was considering buying 16'' tires. If I buy tires they will be in the 15'' variety.

The 615's are old technology. Everything I'v read and heard says they do not hold a candle to the new technology out in the RE-11's, XS's, Advan's, etc. I'm very interested to hear more reviews on the new 615K's.

I am currently running the Dunlop Z1 star specs (coming from advan neova AD07's) and I must say I do like them. They have great grip right from the get go, I would imagine theyd be a great Auto-X tire for you guys into that stuff. I however stick to HPDE's and they seem to do just fine, only thing that is somewhat noticable when comparing to the AD07's is that they seem to get "greasier" faster or sooner in the session. They are a great tire especially for the price. I however will be trying out some AD08's or RE-11's when these are done.

hope this helps

I do kind of laugh when I read people bashing older Azenis as outdated and such compared to the softer tires such as the Star Spec (not including Azenis 615k, which seem to be down the same alley as the other new ones). I recall many people being very fast on the old 215 Azenis years ago, and no one complained about them except for some greasing up if driven hard. The line between r-comp and street tire has been blurred a lot with the latest tires in the last few years, but I'm still happy. I'll just try to drive better...although I failed at that part on 6 yr old 215 Azenis last week, as Adam can attest to, ha.

Actually, I think given just how awful those tires were you did really well, even with that T10 thing. There's only so fast that you can be on rocks like that.

I'v had 1 set of 215's and 4-5 sets of the 615's and I rarely had any complaints. I wouldn't mind trying out the 615K's since the others have served me so well. I would like to try out some different tire compounds for comparison purposes.

After having RE11s, I can't see myself using anything else, but the Dunlops get great reviews, and you should definitely consider them. Dunlops win for price, but the RE11s are an EXCELLENT tire.

All this talk about "better" and "best" I think is a bit misleading. My understanding is that all the tires I'v listed here are better performance wise over the Falken Azenis 615 (old technology now). However, the 615 was a fabulous tire. Many here have owned multiple sets and been running them for years. So all of the tire options I'v mentioned here are going to be good options. The majority of us here are not competing in any way shape or form. Judging by the Tire Rack test they all perform within close margins of each other for the most part. Price really is the deciding factor IMO.

I ran the Khumo XS last year and was very impressed. The tires performed very well. They were predictable, offered more grip than 615's, but did not get greasy.

As a plus, they are one of the cheapest tire selections in this category. Dry grip doesn't compare to my current RE-11's but they are 180 treadwear where as the RE-11's are realistically 120.


I'l spend some time tonight cleaning up the migration issues.

Cleaning it up via a php script wouldn't be hard at all looking at the garbage that got thrown in the tags you could use regular expressions to do an action similar to a find & replace. Granted, that would have to be done with dustin's rights... I suggested what needed to be done when they did the migration but as time drags on it isn't an issue as all of the new posts are fine.

While I heard complaints prior to the purchase I"v never had an issue. I tracked in the wet at ACC at E10, a downpour that later closed the track at Mid-Ohio, and rotated these tires as my street wheels once my 615's were too low for safe street driving. I will note that when I tracked on these in the rain they were near full tread depth.

Some tire prices have gone up a lot. I bought 2 replacement Hankook V12s for my DD last month and they were almost twice what I paid about 20 months ago. There was a $75 rebate for 4 at the time, but Holy Crap, that's a big increase.

Yeah, they seem to be OK. They're decent in wet. OEMs were BS RE050s which were really grippy tires. These were less than half the cost, so it was an easy decision. THe occasional flog thru an exit ramp is the toughest duty they see.

Love my RS3's - but i also used to track my car with Azenis. So it was a big step up no doubt.

My progression:

Falken Azenis 615's (4x sets)
Khumo XS (5x events over the course of a year + street miles)
RE-11 (3x in 2011)

I thought the Khumo XS were superior to the original 615 compound in handling the heat and rain, but I'm not sure the XS's outperformed pure dry traction. This is from memory now and the fact I'm driving on the original 615s everyday in a 215/45/16 setup.

I thought the RE-11's had much more dry grip than the XS's. (They are also a softer tire). High load corners and braking zones were where I noticed the largest gripe differences. Both great tires.

I plan to continue playing the tire field when my current RE-11's wear out. As Erik mentioned the RS3's are on my list. If they are only offered in 225/15 they may be a good/bad thing. Good in that they will probably offer a wider contact patch (won't know until we measure) and but bad in that they will skew the results.

The re11's rub on mine with 600lb rear springs. Looks like for the rs3's, rolling would almost have to happen, for me at least. From the spec sheets, the rs3's section width is .5" wider than the re11's, so at least 1/4" more sticking out. Will have to get under car and see if the 1/4" will rub on anything on the inside.



Post Title: Re: (00TypeR)

Sorry, the EG. The fenders are slightly rolled, but i experience no rub on trailing arm/body of the car when on track (under load, full lock, etc)

I believe people experienced some rub on the RTA when they ran 225's on DC chasis though.

EDIT - I though the question was more geared torward if it's possible to fit a 225 width tyre on a seven inch wide wheel.



Post Title: Re: (navin)

DC's have a tendency to rub the RTA's with 225's, but that all depends on the rim type and tire type.

Possibly useful side note on the Toyo... every size *except* the 195/50 version of that tire uses a dual tread compound. Soft at first and then harder when it wears down. The result is lower grip as the tire should be getting faster due to less tread squirm. The 195/50 size has the "good stuff" all the way to the cords. The effectively shorter gearing of the 195/50 may be better or worse depending on what you're trying to accomplish. I haven't tried it out yet but the supposed "fast" setup is shaved 195/50's all the way around or just at the rear. At the rear, their soft compound and smaller size is supposed to work well and come up to temp quickly on track (especially when coupled with something like the 225 Kook RS3 up front).

No first hand experience on the above but it's all stuff I've gleaned from the fast ST guys.

They put a price cap on the tires. I don't agree with them capping out the RE-11 and using tires from two separate categories. Apples to Oranges when you compare 140 treadwear tires with 300 treadwear tires.

BFG Rival review:
http://blog.365racing.net/2013...-park/


Quote, originally posted by www.365racing.com »

A few months ago I received an email from BFG inviting me to come down to NOLA Motorsports Park in New Orleans to experience their new addition to their tire lineup. I was very honored to have the privilege of being one of the first to test out these new tires. Not to mention it was a great way to escape the cold weather we have in Wisconsin for a few days.

I arrived at NOLA Motorsports Park the morning of Jan 22nd. The weather was great with temps in the mid 60′s and mostly sunny. Perfect temp for tire testing, not too hot, not too cold. After a very informative tire lecture from the guys at BFG, we were ready to put them to the test. My group got to start with the E46 BMW M3′s on a very quick Autocross course. Two had the BFG Rivals and the other two had the Hankook RS3. Right away it was very easy to tell the difference. The RS3′s with their soft sidewall have a more lazy feel to it and lack that crisp, turn in response. I havent had much experience in an M3 so I found this test my least favorite.

BFG Rival Street Tire testing at NOLA Motorsports Park

The next test was on the NOLA Road Course using six Mustang FR500 race cars. Three using the BFG Rivals and the other three on Falken 615ks. I wish I would have had a bit more track time to familiarize myself with the track as most of my seat time with the BFGs was spent learning the track rather than testing the tires. However after going out on the Falkens, the difference was night and day. The 615s had overall less grip laterally as well as very unstable braking compared to the Rivals.

The third test was my favorite as it was something I was very familiar with, a Subaru STi. We had three tires to try, BFG Rivals, Toyo R1Rs, and Hankook RS3s on another autocross course. I felt right at home in these cars and knew how they drove so I really valued this test the most. The BFGs very much reminded me of the Dunlop Starspecs with an improved turn in response over the RS3s (and R1Rs). I was hoping they had a car on the new Dunlop ZIIs to compare but as you know, those tires wont be readily available for another few months.

BFG Rival at NOLA Motorsports Park, STi

Lastly, the Skid Pad. Using 3 Mazda MX5s, one with BFGs G-Force Comp2, another with the Rival, and the third on BFGs DOT R1S. Each car was equipped with a lateral G-meter and around we go. The average results seemed to be .8G on the Comp2s, 1.05G on the Rivals, and 1.2G on the R1Ss. I was also able to notice the break-away point of each tire. The Rivals shared many of the same characteristics of the R1Ss.

BFG Rival at NOLA Motorsport Park, MX5 Skid Pad

To sum things up, BFG nailed it this time. They really will be a top contender in the ST/RT classes as well as other organizations that require 140+ TW ratings. Im convinced these tires will outperform the RS3s, R1Rs, and the 615ks, but the final test will be with the Dunlops.

Big thanks to BFGoodrich for inviting me to the Rival Launch Event.

I've got 205/50 Rival's on order for use with 15x7 K1's... personally, I think the 225/45 will work better on a 15x8. And I think a 15x8 is more hassle than it's probably worth for the back of an ITR.

Simple. Its a safety issue. Old tires = prone to failure.

Offset is definitely a factor. Here is a set of 15x8 TE37SL's in +32. I believe they offered in as low as +25 offset.

Old tires are prone to belt separation unless you only used nitrogen to fill them (i.e. no water vapor in them). I read it on the internet so it must be true.

True on the offset. Those things ^^^ look like they're destined for fender contact...

Those black ones are prob +32 offset. JHP has a run of "black edition" in +35 offset.

+32 with RE11s(205) works fine if you are not too low and you roll you fenders.
+32 with RS3s(225) will rub the fenders even if rolled. Thinking of trying the +35 with the RS3s which might fit it in just right.

I can ask to get an idea on offset.

I'm also curious how wide the tread width is for XX tire on a 15x8 versus 15x7 rim. I think the reality is it is splitting hairs for most of us but I'm still curious.

Only pic I have of comparing the way the tire sits. Too bad I suck at pictures and the height is deceiving due to tire bulge. I guess if I really cared I would have busted out the tape measure, haha.

No I was just curious if it was the same model wheel for all three. I read the 15x8/7 differences.

Once upon a time Luke and I between us had 15x7 K1's with 615's, XS, and RE-11's all side by side. I didn't save the picture properly on my droid so I lost the shot. There was a sizable difference of between the RE-11 and 615. The XS was in the middle.

Should def drop down, tires are cheaper in 15s, haha. Got the rivals mounted last week, will get them on the car this week and smash on it to see if traction control comes on and let you know. Went from 205s to 225s on 8" rim to try and get more traction myself.

Wrong thread... meant to post in the deals thread.

Relative to the performance tire stuff... Hankook is supposed to have a new compound RS3 coming out later this year. Speculation is that it won't be as bad in the wet/cold.

Also talk about an updated Z2 coming next season (2015) along with (possibly) an updated Rival.

Unfortunately, no first hand experience with them... but I've heard nothing but good stuff from the folks who run them. Better than a street tires manners, they won't chunk at full tread, last a long time, tend not to cycle out quickly, easy to drive, etc. The only big downside to them is that they're not a "competitive" tire for racing. For doing track days, I wouldn't hesitate to use them. (They're also supposed to be much better than the universally hated Toyo R888.)

PS
You can also get them at walmart and maybe save a couple bucks...

Edit:
I'm a retard. I realized last night that I was thinking of the NT01. So... back to the original question, I know absolutely nothing about the NT05.

Gonna need to buy a set of dedicated track tires soon but not sure which one to get.

Post Title: Re: (ayau)

I really liked the RE-11's but I haven't driven on the RE11a's or Direzza II's. The Khumo XS are solid tires and would be a good go-to option for me for both dry and wet performance, life, and price point. I liked the AD08's but I chunked one after bending a knuckle first session at Willow Springs in December.

Post Title:

IMO and all that but it's tough to go wrong with the Z2 as a track tire. This being said, I've been very happy with the Rival across several different cars and wheel sizes. And then there's the new RS3 that's been released and will be available in a Honda friend 205 16" size...

PS
I've heard the RE11A is a great street tire and respectable autox tire so I'd suspect it will do fine on track. I'd be concerned the R1R would chunk if not shaved.

Yeah, RS3 version 2. Too bad it's not available in 205/50/15, only in 195/50/15 (yes, 50 sidewall).





Post Title: Re: (ayau)

Im guessing 50 sidewall is not enough for a heavier integra as opposed to lighter miatas and civics and a 205/50 is a better choice?

I got a quote for RE-11As for 540 installed at firestone so I'll be going with that since it'll probably be ok to use during florida summer rains and 5k miles a year usage.

195/50/15 is a smaller tire than OEM so your speedo will be off. It is also a smaller patch of air so there is less protecting the rim and it will be a slight drop in comfort.

RE-11A's are a solid choice.



Post Title: Re: (coolhandluke)

The new RS3 is still available in the 225/45 15 that the V1 was offered in... probably not a great option unless you're running at least a 15x8 though.

The 195/50 seems like a solid option for the rear of the car... it'll come to temp faster and help balance as well. Only potential wildcard is whether or not the ABS is going to get a little freaked out with the front:rear tire diameter difference.

Yeah, would need MASSIVELY wide rims for 225/45/15 to take advantage of that extra tread.

I think I'm leaning towards AD08R 205/50/15 on 15x7 for my next set of tires. Maybe even in 195/55/15 since 7'' is still within the tire's spec. Will most likely get whatever is cheaper. I've seen 205 cheaper than 195 before. Usually you'd think the wider the tire, the more expensive it will be.




Post Title: Re: (ayau)
Posted by: Xian at 2:43 PM 4/22/2014



Yep, the 225 RS3 would, IMO, need at least a 15x8 and preferably a 15x9.

I've been seeing/hearing some really, really good stuff about the AD08R lately... if you're sticking with a 15x7 and don't mind paying the premium over the Z2/RE-11A, they appear to be a solid option.

Honestly, for most folks and most uses, it's tough to go wrong with any of the current Extreme Performance tires. Pick one, don't shove too much tire on the wheel, and then tune the car around the tire.

I got the RE-11s mounted on my 15x6 LS meshies, the pics and previous posts was right it's a wide tire


I'll probably get a better picture.

Im guessing they'll take a couple 100 miles to fully break in? Ride quality is actually better than my bfg comp2s, though I did notice the different steering response with the wider tire, they are much more grippy.

Slightly concerned about the driver rear tire clearance with the quarter panel, I might have to raise the rear perch up if I get any rubbing.



Post Title: Re: (aw614)
Posted by: ayau at 8:53 AM 4/24/2014



Indeed a wide tire for a 15x6 rim. I would have gone with 195/55/50, but I don't think that size is available for the RE11A.

Are you lowered? The tire may not rub the rear quarter because the wheels gain negative camber as they're compressed.



Post Title: Re: (ayau)
Posted by: Xian at 9:12 AM 4/24/2014



I'd be pretty surprised if those rub... I managed to get 205/50 Rivals on a 15x8 on the rear without significant rub. Turn in will be a little on the mushy side (relatively speaking) but I'm sure it'll be fine and, as you said, a huge improvement over the BFG Comp2's.

Indeed a wide tire for a 15x6 rim. I would have gone with 195/55/50, but I don't think that size is available for the RE11A.

Are you lowered? The tire may not rub the rear quarter because the wheels gain negative camber as they're compressed.


Just the OEM type r springs on the lower perches front and back. I forgot all about the camber under compression.

Yeah im noticing the difference in turn in, still not as bad as when I was on the worn out stockers where it just made everything slow, but the grip is there. The real test will be when I take it out to the bmwcca autox event in a few weeks on the airstrip surface which makes even crappy all seasons grippier than usual.

Im enjoying the RE-11A's for autox, perfect step up from the comp2s. I noticed steering is a bit laggier on slaloms, but nothing too bad at all. I ended up lowering the tire pressures to 35 psi up front warm after being at 38 or so for all four wheels. One thing I am wondering, the fronts got really warm relative to the rear tires. I understand being fwd it would do that, but it was quite noticeable just by touching the tires.

Im still not sure on tire pressures, Im guessing I should try to keep the fronts from getting too hot? I dropped the fronts first, but kept the rears, but it was a bit more loose than I anticipated and still turned a similar time,

Now if I can figure out what to do about the 2nd to 3rd gear power on a stock LS motor

As general info, early reports are very positive about the new RS3 V2... appears to be better than the old RS3 in every way. I'm leaning toward these as my next set of tires.

With 205's on a 15x6, I'd have been looking at hot pressures of very high 30's or maybe even low 40's up front. Add air in the rear until it rotates "enough". Probably start with ~7psi extra back there.

Dropping the front pressures with tires that are already a bit pinched will make turn in that much worse/slower... it may help steady state balance but you'll likely lose more time in transitions.

For reference purposes, I tried the 205/50 Rivals on a 15x6 and they're a long way from happy. I had a ton of rollover and shoulder wear. I ended up with a VERY compromised setup of 40F 50R in an effort to control front shoulder wear but keep the car from being too pushy. If you're doing anything aside from street driving, I'd strongly recommend at least a 15x7 or you're going to need to be ok burning up the shoulder before the rest of the tire.

Suspension was 650/550 rates on MCS's. Stock everything else. Pretty low ride height of like 4.75" at the bottom of the front rocker panel.

Posted by: aw614 at 7:12 PM 6/30/2014



damn, do the rivals also run wide at 205/50? Even at 40/50 psi you were still wearing out your shoulders?

ugh makes me wish I snagged those 15x7 SSR Type C's for 500 bucks with tires (Re-11s strangely enough) on CL a month ago that I saw listed.



Post Title: Re: (aw614)
Posted by: Xian at 7:06 AM 7/1/2014



Yeah, they run a touch wider than the Z2's but they've also got what feels like a softer sidewall. As a result, the Z2's seem to do better "pinched". I'll snap some pics later but they got pretty hammered.

FWIW, I think the best times would have been obtained at a shoulder killing 35-36 (which is where I started) but at the expense of wearing the tire even more unevenly. With 2 drivers, that just wasn't something I was willing to do for a local event. Instead, I bumped the pressure, took the hit on total front grip, and then bumped the rear to try and compensate. Far from ideal but it was the best of my possible options for then/there. I've got wheels showing up in a couple days so it shouldn't be an issue from here out.

BTW, $500 for SSR's with good tires sounds crackhead cheap. Stolen maybe?

That was what I was wondering about plus the ad was two weeks old when I saw it and then it disappeared a week later. They were on an EM1 SI from the pictures and in decent condition and no mention of bends. Didn't appear anywhere else like on the Tampa Honda Acura parts page either.

Your local sites are done on a grippy air strip that kills tires quicker than say a parking lot course on asphalt?



Post Title: Re: (aw614)
Posted by: Xian at 9:36 AM 7/1/2014



The site is a decently grippy but abrasive asphalt runway. Whitehouse (concrete) restricted access this year and we haven't been able to get onto it.

Here's an example of one of the fronts:

Versus a rear:

When I started the day, they had roughly equal wear.

Posted by: aw614 at 11:10 AM 7/1/2014



wow that's a lot. I should take pics of mine, my re-11a's have gone through 4 or so events and they don't look as bad.

I would have thought with you being a lot lower than stock and more natural negative camber up front, the fronts wouldn't wear as bad, yikes



Post Title: Re: (aw614)
Posted by: Xian at 11:42 AM 7/1/2014



These weren't "new" this event... they had a handful of events on them from when the car had stock suspension (prior owner + me).

Honestly I think the higher rate suspension was part of the problem... it would load the tires up a ton faster than the stock setup. The result was a bunch of rollover and lateral movement on the wheel. Compounding this was my co-driver who, after looking at video, was using a bunch more steering input than I was. I'm betting that his runs used up the tires more than mine despite mine being faster.

Rumormill Engage:

Bridgestone and Kumho are hunting around for info on what they need to do to get back into the performance tire game.

Toyo should have a revised 200TW R1R in the next couple months. No news on whether all tires will be created equally (good rubber to the cords) or if they'll need shaving, etc. New compound is not supposed to be as heat sensitive. If they keep their current size range, this'll mean 195, 205, and 225 15" sizes as well as a "not overlarge" 245/35 17.

BFG did some pretty extensive compound testing after Solo Nats... suspicion is that they're trying to find a compound that will work at that site with all the "rubbering in" that it experiences. Also word that there *might* be a 245/40 15 size offered... maybe.

TR is supposed to be doing some testing soon on the Z2 SS vs, the RS3 V2...

2015 looks to have a ton of possible tire options on the way!

On occassion I hear about a tire in JDM-land that we don't have here but, more and more, it seems that it's more a timing issue than an outright availability one. i.e. the Z2 Star Spec came out in Japan earlier (early?) this year but just hit US stores in the last month or so. I want to say that Yokohama had a similar thing with their AD08R where it was released overseas in advance of the US.

question, on extreme performance tires in the 205/50 size, do 15x6.5 offer better steering feel over the stock 15x6 like how 15x7 is more ideal to use? Im trying to weigh my wheel options as Im finding a few 15x6.5s I like. Im guessing for future sizes, a 225 tire would be better on a 15x8 and on a say a 15x7, it would suffer like the 15x6s do with a 205?

Personally, 15x7 would be the smallest wheel I'd use on a 205 tire. For 15x6.5, I'd stick to a 195 tire, but the tire selection is pretty limited.



Post Title: Re: (aw614)
Posted by: Xian at 9:54 AM 9/29/2014



Personally, I wouldn't spend the $$ to "upgrade" just a half inch of width. You're running a 4x100 setup, right? I'd go ahead and jump to some of the cheaply/easily avilable 15x8's or 15x9's for the front and run a 225. You only need a pair of them as the 15x6's with 205's will be fine in the rear.

All IMO but:
205= ok for 15x7-15x8
225= ok for 15x8-15x9

This ^^^ isn't hard and fast though... you know a 205 will fit on a 15x6 just like a 225 will fit on a 15x7 but neither is ideal. They both end up pretty pinched. If you've GOT to pinch the tire then you're going to be better off with the Z2 than the RS3/Rival/anything else as the Z2 has stiffer sidewalls and tolerates pinching better. A great example of this is the Solo Nats results; the Z2 was, by and large, the tire of choice for Street/Stock where you're wheel width limited. Go to ST* and the RS3/Toyo were typically the top runners because you can sqaure up the wheel/tire combo.

"New" 200TW R1R seen at SEMA...

Nobody seems to know if this is the same "old" compound and just a re-test to bump up the TW rating or a new compound. I'm inclined to think it's a new compound but there's ZERO info in public hands to support this yet.

You'll be fine. Most of my personal "rule of thumb" on sizing is based on trying to keep autoX performance in a happy place. That being said, there are plenty of folks with EF's running a 225 Rival on a 7.5" wheel. And if you're talking about R-comps then I wouldn't hesitate to shove a 225 on a 7.5 or 7" wheel. The stiffer sidewall helps a TON.

Nice!

Early word was that it was going to be a new compound but now there's commentary floating around that they just re-tested the tires and were able to bring the TW rating up (to a rumored 300TW). Personally, I don't think that anyone who knows the real story is saying anything right now.

If this is an end-run on the SCCA rules, I don't know how well it'll work out. The R1R was nearly banned (or was it actually banned for a little while?) because there were only limited sizes in the "good to the cord" compound. I loved that tire in 195/50 on a light car... amazing performance and sooooo easy to drive. It sucked azz for a track tire though with the things greasing up after ~1 lap.

205/50's

Ahhhh... different compound and construction that's much more heat tolerant.

Detailed answer: most R1R's used a 2 stage tread compound. Soft stuff at first that pretty quickly went to a harder rubber for the rest of the tire. The 195/50 and a couple 17" sizes used the "soft" rubber nearly all the way to the cords. This necessitated shaving down to 3/32-4/32nds or they'd chunk for autoX/track use and even then heavier cars would over heat the 195/50 by mid-run. The 195/50 also had a different/softer carcass that allowed it to put down power better as well as be more fogiving of slip angle. I think the couple "good" 17's had the same construction. Setup for these tires was absolutely silly... my STC EF was running ~5* of static camber with tire pressure in the 24# range. The "best and fastest" STC EF's were running front camber in the 7* range!

Sooooo... the 225/45 Rival, RS3, and R1R are all on back order. Per Tirerack, the Rival/RS3 "may be in stock by February or March". I didn't ask them about the R1R specifically but I believe the expectation was that they'd start getting the new 200TW stuff around now... fingers crossed!

For anyone planning ahead for next year, they'll let you order the tires and get in line (not charge you until they show up).

If you're stuck with the 15x6's, I'd give the new Star Spec a try. They seem to do better than anything else when you have to pinch the tire.



Post Title: Re: (Xian)
Posted by: aw614 at 3:18 PM 1/19/2015



That was my plan by going with the new dunlops It's odd though with the really bad wear on the tires, they have held up a lot better than my friends 225 rivals on a 15x8. One of his are already corded on the outside.

As much as I want new wheels and am tempted on quite a few nice ones, I really need to hold off another year before changing wheels.




Post Title: Re: (aw614)
Posted by: Xian at 5:39 PM 1/19/2015



Yep, there's nothing really wrong with a 205 on a 6, you just have to realize that it'll wear kinda poorly. More camber and pressure will help but not fix it completely.

If your friend is cording the outside of a 225 Rival on a 15x8 then there's something sub-optimal with his setup. Probably needed more camber or more roll stiffness. Possibly more pressure but mine looked fine down in the 33-34# range.



Post Title: Re: (Xian)
Posted by: aw614 at 6:48 PM 1/19/2015



Yeah The wear on my old 195/55s was a lot more even and just the usual outside of the tire. I would have gotten the same type of wear if I had autocrossed on more asphalt surfaces than concrete?

His car was an E30 with revalved bilstein +H&R combo, unsure which wheel it was that corded, but I know he never got a proper alignment and more the toe was roughly estimated and the last event he corded them, the tech inspection found out his tire pressures were in the 20s which he raised, but possibly ran that for a while. Most if not all the events were at brooksville.





Post Title: Re: (aw614)
Posted by: Xian at 7:13 AM 1/20/2015



If you ran on a lower grip surface (some asphalt) then you might have had a little better wear but I doubt that it would have been a night and day difference.

Ah... yeah, with an unknown alignment and stupid low pressures I'm not surprised that it screwed up a tire. Couple that with questionable roll control on the H&R's...

aw614, what's your street mileage vs. track/autox on those tires? That's a lot of outside wear. Looks like you positive camber or something, lol.

I'd just stick with 195/55/15. They'll work better on 6'' rims. I can understand going wider if this is for autox though.

My next tire will probably be 195 on 15x7 rims for more sidewall stifness. I'm not building for any specific autox class though. I would have gone 15x8 if that didn't require any cutting or caused any fender rubbing.

I was at stock camber spec so around -0.9 to -1.2ish I believe. I was also using 40 to 43psi up front so that the steering would feel better. Yeah I have the opposite tire wear of stancebros lol.

I am close to 4k on the tires with events nearly every month, sometimes 2-3 events a month averaging at least 8 runs an event so its fairly heavy use.

I was thinking of getting the 195/55 zii star specs for my next tire and probably a camber kit.

I still don't have any camber kits as I'm worried about slippage, but it seems some people aren't having any issues. I added a little negative camber by lowering the ride height about 0.25''. I've also read people bending the vertical suspension arm (the arm that connects to the upper control arm to the hub).





Post Title: Re: (ayau)

Slippage is wildly overblown IMO. Maybe it's a bigger issue with Hoosiers but I've had precisely zero slipping with my Skunk arms running street tires. You can certainly bend your uprights (it's an old Showroom Stock trick) but adjustable arms are just SO much easier.

As far as how much camber... As much as you can stomach. I've seen the best wear with 3.5-4*.



Post Title:
Posted by: ayau at 6:28 PM 1/20/2015



Is the general rule hoosiers/slicks require more negative than street tires? Is it because slicks have more grip and thus will roll over more?



Post Title: Re: (ayau)
Posted by: Xian at 6:33 PM 1/20/2015

I've seen the opposite. DOT R-comps need less camber than street tires because they have a much stiffer sidewall/carcass. Optimized setups for street and R-comps may be similar but they won't be the same due to the differences in outright grip level.

Post Title: Re: (redGSRguy)
Posted by: Xian at 7:22 AM 1/22/2015

I've run both tires but never back to back on the same car so take all this with a grain of salt...

The RA1 isn't a bad tire at all. It wears well, grips well, isn't too terribly expensive but (IMO) isn't "enough" better than the current Rival/RS3/Z2 SS to justify going with it. If you're in a class where the other guys are on R-comps like Hoosiers you're pretty unlikley to catch/hang with them if you're on the RA1.

I didn't like the R888 much at all. Grip level around the RA1 but the wear was fantasically bad. Really, really, really bad. It wasn't a bad driving tire necessarily it's just that the extra wear didn't correspond to extra grip that I could identify.

I haven't run them but folks seem to love the Nitto NT01. It's in the same market as the RA1/R888 but appears to have better wear and value. You can also get them at Wal-Mart for super cheap and sometimes Discount Tire runs specials on them.

Something to keep in mind with the RA-1 is that they can chunk at full tread depth if you run them hard in the dry. Upshot is that you may want to look at shaving them down to like 5/32nds-6/32nds.

For DE/non-comp sorta stuff, I'd try and hold out for the new Rival or current (but out of stock) RS3.

Any more info on new Rivals? Too bad RS3 don't come in 205/50/15. 225 is too wide for 15x7 and 195/50/15 is too short. Only options left are RE11A and Star Specs.

Nothing solid on the Rivals that I've heard... TR took the tire off their site yesterday but have it back up today (with only 3 sizes). I suspect that they're getting ready to roll out the new tire very soon.

If you're locked into the 15x7's, I'd take a hard look at the Z2 SS. I haven't had a chance to get on them yet but I've heard some really good stuff about them (big improvements over the Z2 and appears to address my gripes with them).

I'd go 15x7.5 but not 15x8 because of rubbing. We're sure 15x8 at +40 offset will rub? I'll have to take a look to see how much clearance I have if go with 15x7.5 at +40. A 7.5 will fit better on 205 tire too. At the end of the day, the extra 0.5'' isn't going to be night and day.





Post Title: Re: (ayau)
Posted by: Xian at 12:57 PM 1/23/2015



15x8 40's will fit just fine up front (I moved my fender liners to the "top" of the fender clips/holes for a little extra clearance. They'll barely fit in the rear with 205's assuming you run at least the stock amount of rear camber. You'll definitely have to roll the rears though with 225's.

If you're not stuck on running a square setup, I wouldn't hesitate to run a 15x8 225 front and 15x7 205 rear stagger. I agree that there's no reason to go from a 15x7 to a 15x7.5.

kumho was also supposed to release a new tire too? How did the XS fare in comparison? I know it was an older tire, and it looked like the 15in tires were discontinued at least the last time I looked...



Post Title: Re: (aw614)
Posted by: Xian at 1:52 PM 1/23/2015

Kumho released the 720 (IIRC) a while ago overseas and it was supposed to be good but not great. Still waiting on new stuff from Kumho and Bridgestone... SCCA's cutoff for tire eligibility is still a ways out (May?) so I'm not surprised that manufacturers don't have the new stuff available yet.

I haven't driven on the XS. It came out when I was either roadracing or semi-retired and then was obselete within a year of me getting back into things. IIRC, they like heat but the grip level isn't on a par with the newer options.

Yeah, I'm on all stock suspension arms. Only lowered about 0.25'', which probably added about 0.2-0.3 of negative camber.

For a DE car, I'm not too worried about getting every last bit of performance. Running staggered would definitely be an option but would mean that I can't rotate the tires.



Post Title: Re: (ayau)
Posted by: Xian at 3:19 PM 1/23/2015



I haven't seen a big downside to running staggered when it comes to rotations. Your rear tires last FOREVER. The fronts do burn down faster but it's offset by the rears that just don't die... Bonus points are that the rears are typically a little cheaper than the fronts.

I got the ZII SS in 195/55/15 mounted today, impressions so far in limited interstate driving on the way home, they seemed to ride a lot better on the same roads than the 205/50 RE11A I had. I'll be able to test them in two weeks at the next autocross. Any ideas on tire pressures? I can probably stick with oem? Going to do a few autocrosses as is to get used to them before adding the camber kit.

Here is how they look mounted, they dont look as wide as the fat re-11as





Post Title: Re: (aw614)
Posted by: Xian at 4:41 PM 2/11/2015



My $0.02 would be to toss on the camber arms before giving the new tires a try. Why? Because pressure is going to be influenced by tire rollover. And tire rollover is impacted by camber. Basically, the pressure you "need" to keep them from rolling over with stock camber will be higher than what you'll need with a couple degrees added.

If you picked up my old arms, you could probably toss them on your car as-is at stock ride height and have pretty decent camber. IIRC, they were set to add around 1.5* over the stock arms where I had them. If you've got (or have access to) toe plates or a couple measuring tapes, you can adjust the toe yourself. You can even use a level app on your phone and get a pretty solid camber reading (I typically got within 0.1* of my craftsman laser level camber guage).

As far as pressure, I'd go for maybe 35psi front and then adjust up if needed (assuming you put on the arms). Otherwise, I'd think more like 38-40psi front. Rear pressures to taste.. Maybe 40-45 or so?

If you've got a lifetime alignment, I'd have them check camber and make sure it's even side to side. Something like 2* should be enough to help tire wear/grip without giving it super bad manners or anything. Zero out the toe or have it on the outside of the adjustment range (slightly toe out).

Yeah, looks like only one 15" size made it over here for the initial roll out. They didn't bring over their wider 18's either.

Good info. The price point isn't bad either. The RE-11's were $137-142 when they first dropped and held for a while. The $100 off coupons is what help most get into those tires. I'm really curious how these will compare. I'm hoping they are stickier than the RE-11A's.

I'll go out on a limb and say that I expect that they're going to be a top-tire this season. I've heard too many off hand comments from smarter folks than me about their expectations of the tire to think that they won't be really good.

I ended up installing the camber kit tonight, too bad its florida cold 49 degrees, but initial impressions are the turn improvement is noticeable, I'll be getting it aligned tomorrow just to be safe, but the car was still going straight.

Is it normal for the steering to feel slightly slower with more camber up front when going straight?

Did you blue locktite the adjustment bolts on the kit?

Can't wait for weekend of the 21/22 to test it out with the ZIISS



Post Title:
Posted by: Xian at 6:45 PM 2/13/2015



I suspect the steering feel is due to the toe being out of whack (toe in IIRC). That'll numb the steering down but it'll come back after it's fixed. I know some folks have complained about a kinda funky feel with lots of camber (like 4-ish degrees) but I never thought it was bad. It got a little grabby on uneven pavement at that point but should be fine with something lower like 2*.

I didn't bother with locktite and didn't have any problems with them slipping.



Post Title: Re: (Xian)
Posted by: aw614 at 12:29 PM 2/14/2015



got the alignment, note to self, lift time alignments aren't worth it, they wouldn't touch the camber and didnt really get it to my spec. Ended up finding a small shop in town open today to get the alignment redone to the specs I wanted.

Decided on -2 degrees up front for now.

For the rear, you used washers and a longer bolt instead of a camber kit? Any reasons for that? My rears are L-1.0 and R-1.5. Im guessing for best settings having the rear evened out at -1.0 would probably be optimal?



Post Title: Re: (aw614)
Posted by: Xian at 3:30 PM 2/14/2015



Sucks that they wouldn't do camber for you.

For pretty cheap you can put together the stuff to DIY all this. Buy a set of toe plates like these: http://www.speedwaymotors.com/...xwAqQ

Get a craftsman laser level with degree readout. Attach that to a piece of angle aluminum and stand-off bolts that space it off the wheel just a bit. Seriously though, you can use a smart phone level app with degree readout and get damn near the same results.

With these two things you can do *ALL* your own alignments.

Only reason I used washers and bolts was that they're way cheaper and easier to adjust from a repeatability standpoint. Agreed on evening it out to 1* at the rear.

Semi-relevant update... I drove on the Z2 SS yesterday. Me and my codriver each got 8 runs at a local site. Open course, some high speeds, decent # of transitions, a couple short sweepers, and one 180* sweeper. These things are light years ahead of the old Z2. Felt like they had better grip and that they communicated MUCH better. Forward bite was plenty good with a pretty sharp turn-in. I don't know how they'll fare against the new stuff coming out but they appear to be a solid autoX option and I'd imagine a good DE tire too.

I guess I'm not surprised they won't do camber for you. 95% of the cars on the road don't have camber adjustments. Either they don't have experience or just don't want to, dunno. You almost need to go to a performance alignment shop to get the alignment specs you want.

What class are you in for autox? Looks like you're in stock class, which doesn't allow any aftermarket suspension parts except for sway bars.

For track days, DD'er, or occasional not SRS BZNS autoX I'd get the cheapo Rival.

For more SRS autoX use, I'd try and hold out... the RS3 is a known fast option and in 225 is a better option than the 205 Z2 SS (assuming you've got the wheel/suspension to support the RS3). The new Bridgestone and upcoming Rival S are complete unknowns but should be good and the Rival S will be in 225 again...

Yep, I should have gone to the other firestone, near my old work place they were much better to work with, done with the life time alignments at that one particular location. I want to try to do it myself one of these days.

I really don't run SCCA, but I usually run with a local group and I've put myself in equivalent of STC/STS I think. One of the competitors said since most of my mods are oem parts and tires, I could just run in the stock gs/hs equivalent class. The local clubs designation of stock is more open than SCCA, allowing camber kits, wider wheels, the exception is only lowering the car. The other groups I run either have an open test and tune everyone is scored on time, and BMWCCA just throws all the 4 cylinder cars in one class so I end up competing against S2000s.

The competition in the modified class is a typically a honda fit, mazda 6, 240sx, and a few other non turbo 4 cylinder cars with similar experience so its a good comparison. The stock class usually has one or two cars and mostly first time autocrossers, so I rather compete with others to get better. There have been exceptions in the stock class a few freaky fast mini coopers and fiesta St's have shown up.

I'll be finding out this weekend how the tires fare, should be nice and warm on sunday.

The Rival S will be in 205 and 225 but the 225 size is one of the things that would make me lean toward it over the Bridgestone/Dunlop. If you're going to run a 205 anyway and it's just for DE/DD stuff, I'd snag the cheap Rival close outs. They may not be quite as good in outright grip as some of the other stuff but they wear well and handle heat well.

Some of the newer tires seem to be sacrificing a little bit of their high temp stability in exchange for better cold grip. Given that BFG is still planning to sell the regular Rival even after the S is released I *suspect* that the S will be better cold(ish) and worse hot. That's just a guess though...

My OEM wheels are running low on tread with the original Star Specs. I'm keeping an eye out. I'm debating on pulling the trigger on some close-outs or waiting another few months. A new car purchase might need tires as well...

Anytime.

If you don't *have* to get something this second and want whatever's the hottest (or you want 225/45's) then I'd hold off. There's absolutely nothing wrong with the 205/50 Rival close-outs as a DD/DE sorta tire though. I don't know if it's already been mentioned here but BFG is going to keep making the regular Rival. The justification that I heard was that they current Rival has a bunch of fans and works well outside of SCCA Solo National stuff (LeMons, Chump, etc). That's why I think the Rival S is going to be geared more toward performance right out of the box but may lose some of it's high temp performance/stability.

TL:DR- If you're not racing on them and want to save some $$, the current 205 Rival is a solid bargain.





Post Title: Re: (Xian)
Posted by: coolhandluke at 9:44 AM 2/20/2015



That was my mindset. My OE wheels are 15x6 anyway, so a 195/55 is preferred but a 205/50 would work as well.



Post Title: Re: (coolhandluke)
Posted by: Xian at 9:51 AM 2/20/2015

Hmmm... 15x6 complicates things. For anything other than DD use, the Rival is still a pretty soft tire (relatively) and I thought it kinda sucked on a 15x6. Even the 205/50 needs at least a 15x7 and is better on a 15x8. If you're sticking with stock wheels and doing any DE/AutoX, I'd go with the 205 Z2 SS. The stiffer sidewall makes a HUGE difference here.

FWIW, the Vette needed 32F/30R psi on Rivals with moderate shoulder wear. Same car on Z2 SS's was 28F/25R and I'm planning to drop the fronts another pound or two.



Post Title: Re: (Xian)

the 205/50 zii ss are cheaper than the 195/55, though I wanted to try a 195/55 again this season since the price difference wasnt that major for me.

What about R1Rs? are they worth trying out eventually? I noticed they came in 195/55/15 also.



Post Title: Re: (aw614)
Posted by: Xian at 10:29 AM 2/20/2015



I haven't seen/heard anything to make me think that the R1R is one to try. Toyo isn't saying for sure but it sounds like they didn't do the rumored compound change and all they did was re-brand the tire with 200TW. IIRC, Toyo had the 195/50, 195/55, 205/50, & 225/45 previously though some disappeared over the winter and have been replaced with the 200TW model. All these except for the 195/50 go to a harder compound partway though the tread and subsequently slow down.

makes sense, in my case I kinda wanted the slightly taller final drive for autox and more even tire wear, either I was getting faster or I felt like I was hitting the rev limiter a lot earlier than before on the 205/50s.

I doubt that either tire is costing you much in time versus the other. They'll probably make their time a little differently though. The 195 despite being taller may be a little more responsive given the width to wheel ratio. The 205 probably had a little more outright grip at the expense of moving around on the wheel more (dulling responsiveness). I remember back in my 2nd or 3rd year autocrossing my ITR in either GS or DS that the "hot" setup was moving toward pinched tires. A 225/45 on the stock wheels was supposed to be the fast setup. I tried it with a 205/50 rear and thought the car drove like assssssss. Looking back, some of it was that I was still new and the rest of it was that all the responsiveness and feedback was GONE. The car was drivable but you had to build in time for the lag between when you turned the wheel and when things started to happen. Overall it was just shitty feeling setup regardless of what the stopwatch said. This was on Kumho V700's and Victoracers, FWIW... The current street tires are about as good grip wise but I still don't think they have the same level of sidewall/carcass stiffness.

Possibly. I know the prior feb Z2 was on close out too but I didn't look at the 195's. Nothing wrong with the Z2 as a street tire and lots of folks liked them for autox but I didn't jive with them. Too little feedback for me. The Star Spec is way better in that regard though.



Post Title: Re: (Xian)
Posted by: aw614 at 3:46 PM 2/22/2015

ran it today this weekend with the proper alignment I like it a lot, I was very slow on a very power oriented course, but the overall handling and turn in felt good, the one thing I notice over the re-11a's is the steering response, it does feel a lot better. I need to try a more technical course at another autocross group next month. I had bad lines on the turn around during the first half of the day, and I think I was rolling over, but tried not to run it so tight the second half.

I gave my old RE-11As to my friend so he can drive to and from events since he corded his rival and is now on hoosiers and was comparing them to other tires in the paddock and wow, they really do run insanely wide.

Most of the turn arounds on this specific autox group seem to be hard on the tires, is it ok to run higher pressure on one tire up front and lower on the otherside?

Glad you like them.

You mean the Hoosiers are stupid wide? If so, yeah... they're huge. A 205 that's bigger than other brand's 225 and a 225 that's more like a 245.

Yep, no reason that you can't run slightly higher on one side than another to reduce rollover. What sort of pressures were you running? How'd rollover look generally?

Per TR, Bridgestone just moved up the release date on the RE-71R... they should start shipping today/tomorrow.

FWIW, apparently Bridgestone did this to try and help out folks who have autocross events the weekend of the 7th/8th with the goal being for them to get the tires either over the weekend or Monday vs. the things going in the mail Monday.

Well, Dunlop is now offering a $50 Visa Giftcard with the purchase of a set of tires. Looks like it's applicable both to the outgoing Z2 and newer Z2SS:

About 200 dollar difference for 18s lol, for my daily that I occasionally autox when I dont take the integra. The price gap between the ZII and ZIISS for 15in was a lot closer that the Z2ss was the better buy.

Im surprised the closeout price for 225/40/18 ZIIs is about the same price I paid for the Z2SS on my Integra in 195/55. I rather deal with 15s than 18s

And here's the new Bridgestone:

http://www.tirerack.com/tires/...Sizes

Looks like the 15" size is in stock with others that will start shipping 3/1.

Initial autoX feedback from folks on the RE-71R is that they're at least as good overall as the Z2 SS and RS3v2. Their sidewall is more like the Z2 SS though so they're likely to do better on narrow wheels than the RS3. They don't take much heat to get working but no real data points yet on how they'll stand up to sustained heat (summer months, double drivers, track days).

Right now, the Z2 SS is cheaper and probably as fast or very close to it... downside is that they (Dunlop) don't offer autoX contingency so I'll expect to see a bunch of autocrossers switch to Bridgestone for the $$.

If you're stuck on running 16's, I'd lean toward these:

http://www.tirerack.com/tires/...1=yes

There's *nothing* wrong with the RE-11 as a beginner tire but the RS3 will a better autoX and track day tire. It's also cheaper. The new RE-71R is supposed to be better than Free Hand Whammy Day at the plasma donation center but they're more expensive and their "extra" potential really isn't needed for a novice anyway.

If you're looking for something that's solidly "not bad" but even yet cheaper, I'd consider these:

http://www.tirerack.com/tires/...1=yes

They're not nearly as sticky as the top-end street tires (like the RS3 and RE-71R, Z2 SS, Rival S, etc) but they're stupid cheap. They were on my 97 when I bought it and I did a couple autoX events and track days on them. They were predictable and easy enough to drive. Not an amazing tire but they're cheap and serviceable for the job.

FWIW, my advice would be to keep an eye out for a cheap set of 15x7's. There are more tire options and they're typically less expensive.

16'' summer extreme tire sizes are super limited. Closest 16'' tire with similar OEM tire diameter would be 225/45/16. I think you're better off getting some 15x7-8 rims mounted on 205/50/15. This is assuming you want to stick to the summer extreme tire options.

IIRC, they spec out around 14.5# or so. I had a set and they definitely felt heavier than my 15x8 Slips that were around 13# (going from memory here). In a nutshell, the Rage wheels are just fine for a basic wheel and tough to beat at the price. Yes, they're more expensive than Millenia's but I'd take the extra width with the weight penalty. These tires (especially the Rival) do way better on a 7" wheel than the stock 15x6 size.



Post Title: Re: (Xian)
Posted by: HondaRcB at 6:00 PM 3/11/2015



I bought a set of the Rage R10s in 15x7 4x100 / 4x114.3. More like 16-17lbs. 34lb shipping weight for 2. Also on mine the lug holes for the 4x100 pattern are tiny. Not sure open ended lugs exist that would be narrow enough. I bought a set of the Advanti Storms and have the Rage wheels collecting dust. If it wasn't for the need for special lug nuts I would keep them. Really nice finish and apparent quality otherwise.



Post Title: Re: (HondaRcB)
Posted by: Xian at 8:36 AM 3/12/2015

They could be that heavy. I know they definitely didn't feel light when I pulled one out. They're insanely cheap though so... :shrug:

I never put them on the car but I know I had a set of 17mm open end lugs that were really narrow. I suspect something like that would work? If not then some sort of spline drive ones should work.

I paid $294 shipped. Can't beat the price. A long, open ended splined lugnut would likely do the trick. If I don't get any bites on Craigslist I'll keep them for wets.

Mixed results for the Bridgestones... some folks didn't like them as much as the Z2SS and ran basically the same times on both tires. Other folks loved the Bridgestone and kicked ass. If it's a tire in your size, it would absolutely be something that I'd check out and they're supposed to be dynamite in the rain. I've heard some early mutterings that they may not do so great in hot conditions (it was more toward cool Saturday and warmer Sunday) but nobody that I know has hot lapped the tire or had it in seriously hot weather.

Post Title: Re: (Xian)
Posted by: Xian at 9:51 AM 3/24/2015



For anyone looking at the RE-71R's, I'd hold off for a little bit... they appear not to wear super well on *some* cars in *some* conditions:

These were from an SCCA National Tour (autoX) last weekend on the west coast. They're the front tires off an RSX-S and have a whopping 22 autox runs total on them. Early speculation is that the RSX is nose heavy, the site super abrasive, and the car doesn't have an LSD so there was a fair bit of wheel spin.

Here's a front tire off a stock FRS/BRZ at the same event. This one had "24 runs and maybe 30 street miles":

http://www.ft86club.com/forums...t=187

This wear seems to be quite a bit higher than folks were seeing with them on East coast events so it may be an outlier... still too early to tell. If I were betting though, these seem to wear very quickly if you slide them around too much and may not be a great track tire... dunno.

Last but not least, the new Kumho V720... initial sizes being offered are kinda "meh":





Post Title:

Post Title: Re: (ayau)

Yeah, the Z2SS is plenty fast, wears well, does well pinched, etc. I suspect that the RE71 will end up being better in every way except wear... how bad the wear actually is will be open for debate until more data points are in. I've seen/heard everything from what I would consider "fast but reasonable" wear to "fuck that" wear.

Yes, the V720 is their new/upcoming street tire. I don't know if it will replace the XS or come in alongside it.

The new Rival-S should also be out at this point with reviews coming shortly...

New info from TR on the V720. It's a completely different size listing than I found on Kumho's site:

Quote, originally posted by Nice Folks at TR »

TR expects to add the V720's to the website within the next couple of weeks. The first round of V720's are still a few weeks away, but due to the lead time and shelf life of our Spring Inside Track print catalog they were included as a "Coming Soon" item. Kumho is fully aware of the SCCA's April 30th deadline and intends to meet it. The initial sizes will be limited to the following (Don't shoot the messenger...plz) While we can't announce pricing yet, it will be the least expensive of the new crop of Extreme Performance Tires. Kumho has not released any information on possible future sizes yet, they will likely wait to see how this first round of product performs before committing further to the US market.

Im not offbase if I think I feel a lot slower on the 195/55/15 ZIISS over my old RE11a's? Last couple autocrosses I've done (around 4), I just don't feel as fast and feel a lot slower. Even though they are different tires, I think the extra width of those wide re11s seems to have made a difference.

Definitely feel like I am falling behind my competition lately, a friend with a b16 eg hatch that is really well set up.

Time to look for wheels too I guess.

On the flip side drove an rx-8 on RS3s, and that was fun

Dunno. I've heard rumors they were getting replaced and then pretty good info that Yokohama doesn't car about a 200tw tire.

Early reports on the Rival-S had been good. Basically, if you liked the old one you'll like the new one. If you're running narrow wheels and can't take advantage of the 225/45 size though, you're probably better off with the Bridgestone.



Post Title: Re: (Xian)

Post Title:
Posted by: Xian at 8:04 AM 5/12/2015



Early info on the V720 is that it's probably about as fast as the Rival-S (assuming the same size tire). Appears that it may wear better and be more heat tolerant which would put it toward the front of the group as a track day or LeChump tire. They're also the cheapest 15" option available right now so good news here.



Post Title: Re: (Xian)
Posted by: aw614 at 12:24 PM 5/12/2015

wow 98 dollars a tire is a good deal, no reports on how fast they get heat? IIRC, the XS was good with heat, but took a while to warm up?



Post Title: Re: (aw614)
Posted by: Xian at 1:56 PM 5/12/2015

I've only seen a couple posts from one person who's run them. They just got into TR like 2 weeks ago... very early info is that they're supposed to be pretty heat tolerant. Dunno how accurate that is though.



Post Title: Re: (Xian)
Posted by: Xian at 7:56 AM 5/19/2015

Sooooo... initial impressions. Keep in mind this is on my C5Z but the general info on the tires should translate decently. I also tried my best to heat cycle the tires before use. Why? Well, many (most?) people were getting some weird "graining" or beveled wear on the middle rib of their RE71R's and a couple folks were having uneven wear on the Rival-S. One person (Andy H) recommended strongly that heat cycling these new tires would reduce or eliminate these oddball wear patterns. Andy's a smart enough guy that I try to pay attention to what he says... as a result, my wear patterns look really good compared to some of the other stuff I've seen out there.

The setup was 275/35 18 RE71R's in the front and 315/30 18 Rival-S in the rear. I managed to squeeze in 2 events this weekend (9 runs Sat @ Vette club, 14 runs Sun @ SCCA). Wear was very good but the SCCA course was really open so it was going to be low wear anyway. Pressures are higher vs. the Z2 Star Specs I was running previously (went up ~4psi at both ends).

RE71R- Pretty "square" fitment on a 9.5" wheel. As to feel, imagine a Z2 Star Spec that had more grip, was more communicative, and more heat tolerant. Braking and turn in felt very good despite the tire being square vs. stretched. Heat wasn't a problem Sat but I sprayed them Sunday to hedge against any overheating. Given the crispness/stiffness, I think these will be great for folks running a 15x7. The 205/50 should work really well on the narrow wheel. There've also been additional reports of these things kicking ass in the wet. Seems like a great all around tire, IMO.

Rival-S- These were kinda pinched on the rear (10.5" wheel) but I really wanted the extra rubber and heat capacity on the rear of the car. With the Z2SS, the rear wasn't "skatey" but you really had to be up on the wheel and pedal the ass to keep wheelspin and slip angle to a controllable level. The Rival-S feels both grippier and more progressive than the Z2SS. Heat tolerance was very good but you can get them over-heated in back to back to back runs if the ambients are high and if they're on the heavy/hp end of the car. For instance, I'd expect folks will need to spray them on the fronts of something like the ITR in the summer but maybe not in cooler weather. Early reports are that this tire is good down through all the tread and to the "bald" point. I understand that the construction is largely unchanged from the OG Rival so I'd expect these to do well assuming you've got at least a 15x8 wheel. I suspect that the 225/45 will do ok on the 15x8 and even better if you have a 15x9.

Some more posts/feedback keep trickling in on the 720. This may be a dark horse candidate and fast tire if they make your size. Folks are shaving the 720 and comparing it to stuff like the prior-gen R1R as far as grip/feel. The fact that these things are CHEAP would have me strongly considering them. No additional info on wear.

For folks looking for track day performance info, GRM should have an article coming out shortly that will compare all the hot tires and how they do with heat/load/extended running.

Some wear pics FWIW:

Still super limited info on the 720... one person ran them (shaved) on the front of a Focus ST at a recent Nat Tour event and they were pretty well destroyed afterward. No clue how they'll do on something like the ITR that's ~1000# lighter with a fair bit less HP. Given the price, I'd still be tempted to try them out...

Talked with Eric a little about the 225/45 Rival-S on an STX ITR that he's driving. Very positive feedback on them for that application. Wear was acceptable and handling plenty good (or it would appear to be given his 4th place finish at the tour). He's running the 225 stretched on a 15x9 so I'd still think this is a tire that needs at least a 15x8. Anything narrower and you'd likely be better off with a 205 of some flavor.



Post Title: Re: (Xian)
Posted by: Xian at 8:30 AM 7/24/2015



Sooooo... since nobody else is posting, I guess I'll give me updated impressions of the BFGoodStone's.

The 71R continues to impress me with it's sharpness and how well it handles heat. If they made a wider 18" tire, I'd probably be running a full set of 71R's. For folks running 6, 7, and even 8" wide wheels I think that the 205/50 71R is likely what I'd pick. If you've got access to a 9" wheel then I'd be looking at the Rival-S. Speaking of the BFG, I like the way it drives and the easy slip angle it'll (generally) carry. These are a great tire but they're more $$ than the 71R, not as good in the rain, and not as heat tolerant. Overall I think the 71R is the better option for most folks assuming equal size between the two tires.

Having said all this, my new stack of tires showed up today (275 & 315 Rival-S):

Current (right side) tires with ~1200 miles and 58 runs total:

The local courses are typically runway events and have (lately) had predominantly left hand turn-arounds. As a result the outer edge of the right side tires is wearing more than the ones on the left (where the inside is wearing a little more).

Current plans are to run the new tires for Solo Nats, bag them over the winter, and then use them for tours next year. The older BFGoodStone combo will get flipped/rotated and used for locals. Not exactly sure what tires I'll run for Expo... bringing my Nat's tires on the trailer and then driving up on either old Rivals or maybe a Z2*spec/71R combo. Dunno exactly but another couple wheels would make it all easier!!! lol



Post Title:
Posted by: aw614 at 12:23 PM 7/24/2015



great update. BMWCCA cancelled the summer events after a really hot june so I've been taking a break and doing more continuous maintenance on the integra.

Haha runway event wear is the same thing I've seen on my tires. I have noticed since I've had the ZIIss on my stock LS meshies, they are wearing nice and even with the same amount of miles driven, the extra camber seems to have helped with that. I still have wear bars unlike before.

So the slip angle on the RE71R's a lot better than the ZIIss? Do you think the RE71Rs would be ok to pinch?

The one thing I was hearing on the vw forum with the guy who has them on his car, he was noticing quicker wear than his previous rivals and re11s.

Thanks

Wear has been pretty decent given the weight (~3100+driver) and limited camber (2.1ish front and 1.1ish rear, IIRC). The price on these things sucks balls though... like $1400/set.

Keep in mind that I've only got the 71R on the front of the car BUT yes. They're a much more composed tire (all aspects of handling) and they do way better with heat than the Z2*spec. I think they'll be fine being pinched; they're closer to a Z2 in that respect than the Rival-S.

Oh, they'll absolutely wear more quickly than the regular Rival and RE11. The trade off is that they're a better tire in every other way...

Edit & PS:
The new tires also seem to wear better and more evenly if they've been heat cycled. Spring for the extra $10/tire or plan to do it yourself, IMO.

The 71R is really very, very good. It's stiffer and crisper than the Rival-S so it does better pinched and, by all accounts and IME, is better with heat tolerance too.

The Hong Norrth boys took the Supra up to the 24 hour race at Autobahn and ran on the 71R's (245 or 255's IIRC). They ended up sidelined for an a hour after the diff blew up but still managed a very respectable 6th overall. The interesting thing was how the tires did. Feedback was tons of grip and way improved over the other (older) street tire options. They handled the heat of the extended running just fine. There was some discussion/concern as to whether or not the tire could actually make the full race distance given some of the accelerated wear they've seen on some applications in an autoX environment... the result was that they did fine. Wear on the rears wasn't too terrible. The fronts were flipped left to right during the diff repair but otherwise no rotations were done. If they had more camber on the front, it looks like they'd have gotten a much more equal wear pattern but, even with limited front camber, it wasn't a huge deal.

Keep in mind, this is 23 hours worth of race pace by a car that led most of the race until the diff blow-up.

Updated tests by TR:
http://www.tirerack.com/tires/...d=202

Things to keep in mind:

#1- 71R does better pinched than the Rival-S (in equivalent sizes)
#2- The RS3v2 may be older but it's not irrelevant (and it wears better).
#3- The V720 didn't do badly at all. Aside from the noise, these may be a decent (and cheap) option. Still haven't had enough folks run them to know how they handle heat or track use though.

Remember the testing TR did was on a pretty heavy BMW, on stock width wheel, with a stock alignment, and with the tires at the recommended pressure per the door placard in the car. i.e. nothing was optimized.

Going to see if I can get pictures of my 195/55/15 ZIISS, I have nearly 4k street and runway autox miles on them and they are wearing nice and even with the addition of the camber kit up front, some shoulder wear, but nothing too crazy.

Thinking of what to buy next or just stick with the same tires again since I am pleased with them and how well they wear since I'll sadly still be on the 15x6s unless I magically find more space for wheels. But the price of the kumhos is really appealing to me, but I'd like consistency and running the same tire again next season.



Post Title: Re: Re: (aw614)
Posted by: Xian at 7:40 AM 9/15/2015



If you're happy with the Z2SS, I don't see a huge reason to change to something like the 71R. FWIW and all that but the front 71R's are wearing about the same as the rear Z2SS's that I just ran for my ~3200 mile street, track, autoX trip. Typically the rear's wear at about twice the fronts so the Z2SS's are doing much better than the 71R from a real world treadlife standpoint.

The heat issues I had with the Z2SS for autoX didn't appear on the track at Expo but I wasn't doing more than maybe 80-85% full-tilt boogie. Would they have overheated if I leaned hard on them? Probably but I don't know that for a fact.

Grip wise, there's a measurable difference between the Rival-S/71R and the Z2SS. Don't get me wrong, the Z2SS is still a really, really good tire but it simply doesn't have as much grip as the newer stuff. It doesn't look I've posted it here but here's a rundown of some testing stuff and info off the C5Z in the last couple months:

I'd been running the 71R/Rival-S combo for several months. Generally speaking, it worked well; the nose was a little sharp/pointy but it wasn't "bad". The worst thing was that we started to overheat the rears as summer rolled in, temps went up, and we were cramming 12 runs (2 drivers @ 6 runs each) into less than an hour. I did a local event right after my last update on the 71R/Rival-S combo and the car was unexpectedly TERRIBLE. It was looooooose everywhere... corner entry, steady state, corner exit. EVERYWHERE. I checked the car over for a loose camber adjuster, wrong toe, loose hub, broken stuff, etc and found precisely zero mechanical issues. This left me scratching my head... what could happen in precisely 1 month to make the car go from really good to absolutely terrible?

The only thing I could come up with was that "something" happened to the tires between events. What could have happened? Well, I was doing a ton of work travel and left the autoX tires on the car between events and the car spent that time parked at the airport. I *think* the Rival-S at the rear cycled out more quickly than the 71R on the front of the car. Again, take this with a grain of salt but that's the only thing I could come up with.

To test the theory, my codriver (Nelson) and I took the car up to a semi-local TnT. We brought the fresh 275/315 Rival-S setup as well as the 275 Z2SS and older 315 Rival-S pairs. The all Rival-S setup felt really, really good with just the slightest amount of hesitation at turn-in. In this case, softening turn in just a little actually makes the car more driveable so this was a good thing. As we built heat into the tires and the day got hotter, we could get either end to grease up a little about 75% of the way through the run. It was still driveable, just a little loose or pushy. Next up was putting the older 315 Rival-S at the rear. The car was generally ok for the first run (though a touch looser than on the new tires). That quickly morphed into a very loose setup as the tire seemed not to like the heat as much as the newer tire. For the final couple runs we put the lower grip Z2SS on the front. This was a pretty wild change as the car immediately started to understeer in steady state cornering BUT you could push it hard everywhere because the back end was super planted. With this setup (275Z2SS & old 315 Rival-S) we ended up getting awfully close to our fastest times on sticker Rival-S'.

Because of the speed we could roll with the pushy setup, I decided to add a little rear camber to the car and take out a little front rebound before doing Expo and Solo Nats. The thought was that I'd get a little better rear traction with the car loaded up in a corner while also slowing the rate that weight transfer to the rear on throttle (the looseness was generally higher speed stuff from apex to exit).

Translating this to the ITR:
If you get the Rival-S be careful about heat cycling the car via daily driving. Given their tread depth, cost, wet weather performance, etc. I'm still not convinced they're the "best" tire for most people. If you can put them on 15x9's up front and only run them for track/autoX, I think they're *perfect* but probably not ideal for DD'er use or if they're going to be pinched.

The 71R still sticks out as a helluva tire. Stiffer sidewall so it's better pinched, seems less heat sensitive, and possibly less sensitive to cycling. They're also going to give you a sharper turn-in at the expense of making the rear a little more knife edged.

The Z2SS is still a great "do everything" tire. Not as grippy as the newer stuff but still plenty fine in most cases/situations.

I spoke with one person at Solo Nats who was running the Kumho. She ended up barely out of 1st place in STS Ladies Class so the tire doesn't exactly suck. Her commentary was that they were better at putting down power than the 71R but give up a little lateral grip. I didn't think to ask about wear or heat tolerance. At the price, I'd be awfully tempted to give them a try... sooooo cheap.

Lastly, the 71R and Z2SS have something close(ish) to 5,000 street miles, 65-70 autocross runs, and 6 or 7 sessions at Gingerman on them. They're all a little above the wear bars (2.5-3/32nds) and are fine in the dry but pretty spooky in the wet. The last 300 miles home were in monsoon rain where the car would hit standing water and walk laterally anytime I was over 53mph or so. Not a fun way to end the journey; especially with a heavy tire trailer in tow.

I am still debating which tires to purchase for the DD S2k... 71R's vs. Z2SS or should I go down a step and stick with the current Pilot Super Sports. Rain is my only concern and I don't see myself tracking it over the ITR.

If you're not tracking it and not autocrossing it, go with the PSS's. They're not "much" worse in the dry and way better in wet/standing water. They'll also wear better and have better road manners.

Ran across this a little bit ago... 245/40 15.

Hope it's a good option!!

Yeah I would do the PSS or any max performance tire on a daily. A few weeks ago I experienced slight hydro planing on my worn ZIISS on the interstate and immediately got off and took it slow on the way home.

245/40/15? Is that the magical size many honda owners were looking for? I wonder how Maxxis are

I pinched a 245/40 ZII (Non ss) on a 17x7.5 for 150 on my daily to try out for a few events in the next few months. Not sure how they'll do, but it'll beat wearing down the tires I need to get to and from work safely

Looks like Kumho is stepping up with a 225/45 15 now too:

http://www.tirerack.com/tires/...Sizes

Suspect that this should help close the gap from the 205 V720 to the 205 71R. Given the price, I've gotta think that these would be a decent track day tire or "aggressive" street tire choice.

There've been increasing numbers of folks having problems with the V720 delaminating in hem (starts at the center rib). Most of this is LeChump use but one instance was in a FoST being Autocrossed. Probably not a big deal for an Integra or ITR but something to be mindful of.

I think I saw the pics of that over on the sandbox, that's concerning to me at least in the summer due to Florida heat.

I noticed the v720s seem to heat up fairly quick and even on a cold (Florida) day highway drive, they were warm, I always read that the older XS didn't heat up as quick?

Yeah, the SandBox thread was what prompted me to come here and share the info.

Here's the pic for those wondering:

You're correct about the XS... it came on the scene when I wasn't actively autocrossing but everyone I've ever spoken with said it needed, and could take, a metric ton of heat. It appears the V720 may not be the same sorta droid.

Some good info in here. Ill spend some time reading through the thread over the next few days. However wondering if I can get a quickie recommendation on the following.

Track-only wheels for the ITR will be 15x7 for HPDE events. Camber and toe settings not too crazy and corner weighted. Cost is a factor but not a deal breaker if the tire is worth the extra cost. Would like to be able to get quite a few events out of them this year. Of the tires you guys have discussed, which would you recommend and in what size? Im thinking 205/50 is pretty standard for 15x7 but curious what you guys think.

For the street, I have 16x7 wheels with probably no change to camber and toe settings. Happy with current azenis 615 on my stock ITR wheels and have no problem going with them again but I have no experience with them on 16s or 7" wide wheels. I tend to get decent life out of azenis on the street but not sure if there is a better option as far as price, noise, wear, wet vs dry, size, etc.

For 15x7 stick with 205/50/15. Actual tire width will vary.

Street = just get some decent tires that handle rain well IMO. No sense in spending good coin on street tires.

Yup ^^^.

The "best" 205/50 15 200TW tire out right now is the RE71R. If you want to sacrifice a little grip in exchange for longer life, the Z2 SS is a good option but it's also more sensitive to over-heating and greasing up. I am still a fan of the OG Rival for a track tire but #1- I don't know if you can get them and #2- They're still a little soft feeling on a 15x7... they prefer a 15x8.

All of the 225 stuff will do better on a 15x8 (or 15x9) and isn't likely to be particularly faster than the 205 71R. The 245 Maxxis is still un-tested.

TL;DR: Get the 71R unless you want to save a couple bucks, then get the Z2 SS.

The Azenis 615k doesn't hold a candle to the existing lineup. The 615k is simply old technology at this point. I would argue the Khumo XS is far superior to the 615k and the XS itself is 5-6x years old now.

The prior/original isn't a bad tire really. My co-driver tried them on the rear of his swapped EG and was happy with them. They're not going to be as fast as the newer stuff *and* they're only 140TW but they're a great tire for the money. Biggest downside that I've heard with them is that they can overheat on the front of the car.

Good to know. Being out of the caR for so long the Azenis still feels like a good tire to me. Although I did get them pretty slippery at E9 or E10 I forget which one. I remember not being too happy about that. Looking forward to trying something new.

The OP has been updated with new information. Time to clean out the old info.

Ask: As new tires are purchased. I'm curious if we could determine a concrete way to measure the actual tread width via MM or inches. The difficult part here is there is a high chance of error.


We may want to fire off an additional thread for rcomps in the future. One step at a time...

Maybe a best practice would be to request a pic with the measurement? If you get a couple of these, you can compare them to the tread width specs on TireRack... should be awfully close as their tread width measurement isn't really impacted by wheel width.

I agree with a spinoff thread... maybe break it into Extreme Perf (~200TW+) and then an R-Comp/TrackDay Tire thread for anything under 200TW?

Thanks Ryan

I read the second article via a FB yesterday but hadn't seen the first one before. IMO, the testing methodology is a little mediocre BUT it for sure goes to show that the 71R is way ahead of the old crop of 200TW tires (RS3v2, Z2SS, Rival, AD08R, and anything from Falken/Nitto). A couple observations from the peanut gallery WRT the "test" against the NT01: was the car set up for the NT01? If so, then there was additional time to be found by setting it up for the 71R. The converse is true also. Andre set his fastest lap on the 71R at the end of a session. This seems to indicate that he may have still been feeling out the limits of the tire/car combo. There may have been more time out there with more acclimation.

Aside from the nitpicking above, it's still a pretty convincing data point showing how fast the 200TW stuff has gotten...



Post Title: Re: (Xian)
Posted by: coolhandluke at 9:18 AM 1/2/2016



Strong points Christian and I totally agree and highly question the testing methodologies. I also cringe at the mere concept of comparing an rcomp vs. any street tire. However it seemed like a positive take away over all for the RE71R so I hope the information is fruitful.

What do you mean by setting up a car for a particular tire? Does a certain tire like more/less camber and toe, air pressure, etc? How would you know without blowing through sets of tires to find what works best on your car with your settings? Is there a general rule that can be followed?

Nailed it. Street tires typically don't need as much negative camber, where as an rcomp tire will want in excess of -3 degrees.

Finding out what works "best" for you takes effort and data. Hot pit and read tire temps across the face of the tire is one example.



Post Title: Re: (coolhandluke)
Posted by: Xian at 2:09 PM 1/2/2016



I'm in the middle of some cocktails so don't expect a super coherent response... In a nutshell, I'll go 180* from Ryan. R-comps for sure like camber but the amount of camber depends on the tire. Maybe we're at a convergence here? I know running a 225 Rival on my R did best with ~3.5* up front. It worked with less but I had to run higher pressure to limit rollover. The 71R has a stiffer carcass so it can run either a lower pressure (relative) with ALL THE CAMBER or a the same pressure and an equal amount of camber. What works best for a tire depends on the vehicle, wheel width, spring/shock/bar, application (track or Autocross, then DE or TT or Club Race), and driver style. Point being, there's not a silver bullet but you can get close-ish just by asking around for what others run. My suggestion is to look at the tire. If the outside is getting beaten up and you're already higher on pressure then add camber. If it's getting beaten up at 30psi then add air before camber. Etc.

FWIW, my B16 EF had like 4* of camber up front with 225 Rivals in a 15x9... That car was dynamite.

Oh and toe isn't that variable across tire choices from what I've seen. You need to adjust it for sure to get the right balance (along with camber and springs, bars) but it's not hugely different based on tire.

that driver side tire looks stretched in that pic

great tips, I probably should have played around more on my set of ZIISS before I corded one up front, I was running higher pressures (40psi) and -2 degs of camber and tire wear was even for the most part, I should have dropped them a bit to observe the wear, I didn't really kill my shoulders until around the 4000 mile mark with 100+ runs and street driving so I can't complain.

Now to see how the kumhos will hold up. They certainly feel grippier than the ZIISS on my first event with them.

Really want to keep my setup (with minor camber changes) until after I decide what to do with my motor and do a track day as is, must resist stiffer springs...lol



Post Title: Re: (aw614)

Yup, street tires have softer sidewalls than R-comps. IIRC, I was down around 31-32 psi on the front. Even at that point, rollover and wear was looking good and the turn in was still solid (because they were stretched and I was on 800# fronts). The tough thing is that all the variables are inter-related; change one and it impacts the others.

Thanks for the input (correction?) Christian. My thought process was rcomps generally prefer more camber the street tires but maybe that's outdated with the new tire lineups? For the Rival, how does its camber characteristics compare to an older tire, say an a XS or 615?

Moar good infoz

For comparison sake, I recall running Azenis on lower pressures in the past, like 32 or so cold and didnt run much neg camber with stock sized wheels. This time around Im on 10/12k springs, but havent yet gotten my alignment settings or tires sorted out. Ill be staying on 15x7 wheels for now.

Based on info so far Ill probably try the 71r. Should I start with a higher pressure than the Azenis and maybe a little more camber and see how it feels and how the wear looks? Stock sway bar with rear upper shock bar.

Cant wait to get out there this year.



Post Title: Re: (coolhandluke)
Posted by: aw614 at 8:24 PM 1/2/2016



about the comparison with rcomps, if the sidewalls are stiffer, it still seems on macstrut cars, they are easy to cord a hoosier or any rcomp if you aren't careful while autox'ing compared to the 200tw street tires due to the lack of camber?

At least it seemed that way with friends on macstrut cars (FWD and RWD) that ran hoosier take offs or the cheaper bfg r1, etc and a 200tw tire like the rival on the same cars. The rest of the tire would be fine but the outside would be corded on the hoosier, whereas it seems like while the outsides seem to wear fast on the street tires I've never really seen one corded with the rest of the tire still being good....

Honestly, I can't really say. I ran the old Azenis 215's then went to Victoracers, V700's, and then Hoosiers (R4, R5, R6). The XS and 615 were around during my triplet-induced racing sabatical and/or when I was running ITA where Hoosiers were the hot ticket.

What I wonder (and this is just me noodling on the differences) is whether compound related mechanical grip has hit a point in street tires where they're generating so much (relatively) grip that the carcass has trouble holding the tire in position. The result is that you've got to throw camber at the tire. Add to this some of the "ah ha!" moments* that were had by the ST Civic guys and there are setups being used that just weren't "a thing" even 4 years ago.

*The ST Civic development came up with some really amazing pieces of data. The 195/50 R1R they were running had a very soft sidewall (similar to the Rival). As a result you had to run higher pressures to keep it from flopping over. The higher pressures gave up grip though... the solution was to add camber, more camber, ALL THE CAMBER, and run super low pressures. The final "fastest" setup was something in the range of 6* camber with 22-24psi. lol

I'd try cold pressures in the same neighborhood as the Azenis (30-32psi). I wouldn't willingly start with under 2* of camber and would expect better wear/grip with 2.5-2.75*.

McStrut cars have shit for a camber curve... picking up close to zero camber on compression. As a result, you really want to run a pretty hefty amount of static negative camber to keep the tire "flat" even when the car rolls over. With only ~2.5* of camber the STi was beating up the outside of the front tires. I've bumped it to 3.5* to see if that helps. If that's not enough then I'll fiddle with the camber bolts and aim for 4*.

Something that I think is worth mentioning is that there are soooooo many variables that go into setup. Don't take anything I post as "gospel" as there are different ways to get to the same end point. Front stiff vs rear stiff. Square tire setup vs. staggered, etc.

Semi-interesting, rumor mill sorta stuff on the Maxxis VR-1... some folks are already saber rattling about the design of the Maxxis. Basically, it's a suggestion that the tread is made with "variable depth" outside of the center ribs which would result in a "full slick" as the tire wears down (or is shaved).

https://scontent-sea1-1.xx.fbc...F7976

Link with a close up pic of the tire ^^^^. I see what folks are referring to with the steps on the side of the center channels but I'm not convinced this is a problem or advantage for the tire. Nobody really knows how these things will do but I suspect we'll find out shortly as someone makes the jump to them.

For anyone playing along from home, 3.5* on the front of an STi is adequate but still not ideal. Looking at either more camber at the front or stiffer springs next. The double wishbone setup on the front of the DC/EF/EG is magical... so superior to struts that I don't even know how to put it into words.

Dunno if it's been mentioned yet but there's speculation/info that there's a new Rival-S coming this season. Not sure if it'll have a different tread design but it's supposed to have stiffer construction (like the 71R). I've seen one tire seller offering a discount on 2015 date code Rival-S inventory and wonder if that's an attempt to move them before the newer tire.

Thats interesting. I was going to go with the 71R but if the Rivals are going to be discounted soon then maybe Ill jump on those unless the new one is hands down better than the old one and/or the 71R. Any info on that seller with the Rival discount would be appreciated so I can take a look.

Phil's Tire has limited quantities of the 205/50 at $113/tire. No 225's listed. Given that the 205/50 71R is only $117, I'd still go with those if it were me.

Just to update everyone, my kumhos experienced the center tread delamination christian mentioned. It happened after ~1,000-1,500 miles and 40-50 autocross runs. I really did like the kumhos for autocross, but it seems they need to be run at lower pressures and/or head cycled before using, something I did not do as I drove it around 500 miles of street driving before I did my first event on them.

So I just got RE-71Rs to replace them after talking to tire rack, they offered me 20% off two tires so I decided to just go for them, probably right before the rebate Bridgestone usually offers oh well lol.

I am going to try them out tomorrow at the event I am helping out with. First impressions on the street is at least they don't sound like I have a bad wheel bearing and they seem to ride better even at the same tire pressures It's been rainy all day so I didnt push it much. Next time I'll probably try tire racks heat cycling service when I get my next tires.

Just got my 71Rs on recently. They are super quiet, and very responsive. Especially compared to my street tires BFG Sport Comp 2 which are pretty loud. Very much looking forward to tracking the 71Rs. And also tempted to just drive them on the street but I dont want to kill them lol.



Post Title: Re: (RTW DC2R)
Posted by: Xian at 4:05 AM 3/28/2016

IMO, street driving isn't awful or anything but the DD'er heat cycling combined with baking in the sun all day is going to hurt their performance long(er) term. If you're not a bleeding edge, Type A Autocross guy, I don't know that you'll even notice the drop-off that much. In fact, and this is a guess, you may get longer life out of them as the tread hardens slightly (like what happens with the RA1).

In related news, the Maxxis VR1 is now being offered for sale direct from Maxxis. Get those 245's while you can!!!!

205/50/15 on stock 15x6 wheels with -2 degrees of camber up front and around -1.0/-1.5 for the rear (I need to even it out)

for initial tire pressure, I started off at F:35/R:37 on the concrete surface for autox. I don't think I found their limits yet, and very response tires even for being pinched

I'm on the same alignment I had after I had the kumhos mounted, but not sure how much that's changed since.

RE71R would be my go-to for that wheel size.

In a nutshell, and it's probably worth putting it all in one spot so it's easier to find:

7" wheel
RE71R is the hot shizzle still

8" wheel
205 Rival-S and RE71R are both options. Similar performance envelope but they'll drive differently.
225 Rival-S is also an option but will feel a little sloppy compared to the 205. Expect similar times overall with better heat capacity for forward bite but sloppier turn-in.
225 RS3v2 is a solid tire with better heat capacity/life than the other tires but it'll also be slower than them. Could run this on a 9" wheel too.

9" wheel
225 Rival-S is the hotness here. Super happy on a wide wheel and faster than all the other stuff above.
245 Maxxis VR1 will work on a 9" wheel but reports are that it works better on a wider wheel. Still too early to know if it'll be as fast as the Rival-S.

10" wheel
245 Maxxis territory here. It's the only 245 15" street tire out there and may be faster than the Rival-S... dunno yet.

There's also a new Yokohama coming out soon too.

Posted by: RTW DC2R at 6:53 PM 4/27/2016

My initial impressions of the 71R are they are pretty damn good. I got 3 sessions on them tonight, they were brand new with 3 miles on them (when I test fit the wheels recently).

First session I was running a little late to grid so didnt bother trying to find the air station and I went out as they were. Pressures were on the low side but I knew they would come up some. Fronts were around 32psi, rears were around 31psi. I also had my suspension set to full soft, and the car felt really squirrely. Combination of soft shocks and soft new tires wasnt much fun. Tires also took a while to heat up (it was a chilly afternoon in the 50s, and they had 3 miles on them). Eventually they started to heat up and get a little better. Pressures at the end of the session were up to around 38 front, 35 rear.

Second session, turned the shocks to medium hard, and tire pressures were around 35f and 32 rear at grid time. The car felt much better almost immediately. Partially because of the shocks Im sure. I really started to push them and eventually spun Once they let go there was no catching it. Pitted, gathered my wits and went back out. Was really starting to feel and hear the tires working. That only made me push it more. Pressures at the end of that session ended up around 42f and 38r. Visually you could tell they were warming up.

Third session I left pressures alone and cranked the shocks to full hard. Even better, I was almost able to do whatever I wanted with the car. Rotation was good and didnt let loose. A couple hairy off camber moments but the tires held. If the car was planted through a turn I could rip full throttle without much worry (think long sweeping bowls). Started to get a vibration under hard braking toward the end of the session so pulled in early. Once in the paddock I could tell the tires were ready. They were sticky to the touch. Pressures ended up about the same as after session 2.

All in all very happy with them. Once I get a couple things sorted out Ill be back out there for more.

Post Title: Re: (AssPenny)

Folks are using them as autocross, street, and track tires. Tons of DD'er stuff on them is going to cycle them out more quickly but occasional use isn't a big deal, IMO.

FWIW, saw in my FB feed this morning that the 205/50 Maxxis VR1 is back in stock. With the 71R out of stock, this may be a solid option. Still limited reviews on them but word is that they're "almost" as sticky but wear better/longer.

PS
Great review on the 71R's!



Post Title: Re: (Xian)
Posted by: RTW DC2R at 6:36 AM 4/28/2016



Craig, Im not sure what the wear life is going to be on them yet, but they are fine on the street and super quiet. They are quieter and more comfortable on the street than my BFG Sport Comp 2 (but those are 16x7). Im toed out in the front though so I definitely wont put many street miles on them. I actually drove them home from the track because I was facing a 2+ hours drive and too lazy to wait for the lugs to cool down and swap my other wheels. Just wanted to get on the road.

Christian, any suggests on the pressures? Does what I experienced sound about right to you given it was chilly afternoon session? Its crazy that they just kept getting better as the sessions, psi, and temps kept going up. I was keeping pace with several BRZ which I was happy with considering it was my first time out in years and first time on track with this R. If it wasnt for my brakes frustrating me then I could have gotten better info. Not sure what the psi limit will be but I might start my next time out around 36-37 range unless its a warm day.



Post Title: Re: (RTW DC2R)
Posted by: Xian at 7:55 AM 4/28/2016



Off the cuff, I'd probably try targeting lower hot pressures which means lower cold pressures. That being said, it's really rare that I ever have events in the 50's so I don't have much experience with them in cold temps. Additionally, I've been running these on my C5Z previously and STU STi now so pretty apples and oranges comparison. Still, if I had an R with 205/50's on 15x7's, I'd likely be aiming for 38ish hot front and then whatever it takes to make the back walk/dance... but that PSI will also depend on tire rollover which depends on camber and springs and bars.

One thing that I've seen/heard over and over is that the 71R/Rival-S are both pretty pressure agnostic... meaning that, outside of rollover/wear, you'll often get the same or at least similar performance out of them across a 3-4psi spread. The upside to this is that there's not a huge issue with running them a little over or under the sweet spot.

<--- runs around 30psi for the fronts on the autocross STi.



Post Title: Re: (Xian)
Posted by: RTW DC2R at 8:31 AM 4/28/2016



Is it better to have the tire rollover some? I'll have to take a look at the tread and see how far the tire was rolling but I dont think it was very much. If a little rollover is good or OK then I can certainly try some lower pressures but maybe keep the suspension full hard this time around. That would be the opposite of what I had the first time out so I can give it a shot.

For me right now, just stock bars with a rear upper strut bar. Camber around -2.5f and -1.5r. Total toe out 1/8th in the front, 0 rear.



Post Title: Re: (RTW DC2R)
Posted by: Xian at 9:31 AM 4/28/2016



Yup, some rollover just means that the tire is working the contact patch and your pressures aren't "too high". Here's what mine look like and roughly what I'm aiming for:

You can see in the pics above where the tire transitions from the grippy tread compound to the sidewall compound. I try to run right at/barely over that transition.



Post Title:
Posted by: RTW DC2R at 10:03 AM 4/28/2016



Thanks for the info as always. Yeah I definitely have room to come down then. I dont think mine were anywhere near that transition to sidewall. I do like a firmer feel but if I can get more from the tire with a lower pressure I will play around with it.



Post Title: Re: (RTW DC2R)
Posted by: Xian at 10:38 AM 4/28/2016

Anytime.

Yeah, try a little less pressure to start with but run the shocks a little higher where you like them. Worst case scenario, you bump pressures back up.

Not super useful to anyone at the moment (no ITR sizes currently) but he new Nexen is supposed to be the sister-tire to the next gen RS3. Early reports is that it's about 0.75 seconds slower than the 71R on a 69 second course. Supposed to have really good wear though so it may end up being a great track day tire. It's cheap as hell too...

I'm probably going to be buying my tires in two weeks or so. I'm going 225 as I'd like like the extra traction with the power I'm putting down. So pretty much my options are limited. Rival or venus rs3 v2. The v720s are the cheapest option but have been on back order of a while. I'm guessing my best bet from what I've read through here would be the rivals?

#1- if you're doing a 225 then the Rival-S will be the fastest tire at the expense of a higher wear rate. The RS3 will give up some speed in exchange for longer life. There's also the Maxxis VR1 in a 245 if you've got a 9 or 10" wheel... it's almost as fast as the Rival-S (according to the latest GRM) but lasts quite a bit longer.

#2- No clue on 16" fitment for the R. Seems to me like you could probably get it to work for a street car but it would be a handicap for track/comp use.

#3- Yup, more and more stuff coming out it seems. There's the new Federal 595-RSRR (I think) that's being released... it's 140TW so I think it'll have pretty limited appeal and limited data/reviews. There's also the confirmed news that BFG changed their carcass/belt design slightly for the 265 and smaller widths in an effort to bring some steering sharpness/accuracy back into the game. This may mean that the new, new Rival-S works better without having to do a crazy stretch on it (i.e. 15x8 fitment won't struggle as much).

WOW, so after I posted up about my experience with Kumho Tire's poor customer service and equally poor product, Kumho commented for me to call them and said that "Our quality assurance team wants to help you," and gave me a number to call. I called earlier this morning and was told that yes, they've had issues with the tire doing exactly what mine did, and that they wanted to come back and provide proper customer service and help to correct the situation. A bit later, I received a call back from the same person I spoke with last week, whose customer service I felt was initially lacking. Surprise surprise, this gentleman proceeded to provide about the same level of "I'm right, you're wrong" service as before, and even went so far as to tell me they had changed their advertising because THE KUMHO V720 IS NOT A PERFORMANCE TIRE, AND SHOULD NOT BE USED AS SUCH.
So, in order to make sure that everyone is aware, Kumho themselves admit that their marketing was MISLEADING and INCORRECT, and the V720 is NOT a "performance" tire WHATSOEVER. Be warned, don't buy into the hype, and DON'T SUPPORT THIS GARBAGE COMPANY AND THEIR GARBAGE PRODUCTS! The proof is in the pudding - have a listen for yourself! I will NOT be purchasing another product from Kumho, be it for one of my vehicles street or race OR for any of my customers' street and/or race vehicles, and I would recommend against anyone else using them. I cannot believe that they would act this way and consider it 'customer service.'
I NEVER asked them for anything unreasonable (only for more info on how to achieve the best results out of a tire they promoted as "bred for performance"), and I didn't ask for any sort of refund or ANYTHING - I simply posted a photo of how their product performed along with a gripe about their product quality matching that of their customer service, and Kumho Tire reached out to ME and "pretended like they wanted to make it right". Absolutely flabbergasted at how Kumho is handling what is OBVIOUSLY a misrepresentation on their part. Shame on you, Kumho Tire! SHAME!

Christian, your thoughts?

I noticed the sidewall on the 71R has a few little arrows, Im guessing thats indicating the contact patch limit? In the below pic, the red line is about where my wear shows up on the fronts on my R (forgot to take a pic). Does it look like I have some room to spare and maybe I can bring pressures down a bit to maximize contact patch? Next track day is tomorrow so I plan to mess around with settings.





Post Title:
Posted by: Xian at 5:05 AM 5/10/2016



The little arrows are actually to show where the wear bars are located across the face of the tire. That being said, on this tire they tend to line up with where I've been letting the tire roll over to... basically in line with where the lateral siping thins down at the sidewall transition.

Based on your red line, it appears you could go a little lower in hot pressure and potentially improve mechanical grip.

Hey Christian, how does this sidewall contact patch look to you? This is with 3 HPDEs (one dry and cool, one super wet, and one warm and dry). This last day was warm (low 80s), and pressures in the front were getting to 42* or so and I was getting some push if I went all out or by the end of the session. Rears were getting to around 38. I think Id like a little more rotation as well. Suggestions?

The car was also starting to feel like it had some decent body roll which was a bit unnerving over some of the transition bumps to the infield sections. Definitely will be getting high spring rates.





Post Title: Re: (RTW DC2R)
Posted by: Xian at 4:58 AM 6/20/2016



Wear and sidewall rollover looks good... appears there's a little room to probably lower the fronts. Maybe try dropping hot pressures to 38-39 and see how it drives/looks? For the rotation thing, you can start bumping rear pressures (cheap and easy). Try a 4-5psi increase and see how the car drives. If it gets better then keep bumping by 2-3psi until you get it how you want. Be careful though as the higher rear pressure will also make the car break loose more quickly when/if it finally comes out on you.

Thanks d00d. Would bringing rear camber from -1.5* to closer to -1* have a similar effect in the rear? I'll probably start playing with pressures in the rear first but just curious.

Anytime

Yup, changing the rear camber to [Not Ideal] will throw away rear grip also. You can get there either with low camber (1*) or with really, really high camber (3+*).

Im also on stock sway bars so might have to look into a rear bar. Though the only real issue with rotation I seem to have is later in sessions so Im thinking Im getting more grip in the rear as tires heat up.

Next event is Wednesday so hopefully get to toy around with settings then.

Yup, if it starts out balanced and then gets pushy, it's likely a case where either the fronts are overheating and getting greasy or the rears are coming to temp and getting grippier. More rear bar should (in a perfect world) create more slip angle back there earlier on entry and let you modulate throttle to keep it in the "happy place" through the turn. FWIW and all that but I loved the ASR 0.120 wall bar on my car with stock springs.



Post Title: Re: (Xian)
Posted by: aw614 at 2:41 PM 6/21/2016



interesting, and you were using the asr rear sway bar on the bfg rivals? it never felt it was overkill in the rear? Did you make any rear tire pressure changes with the asr bar?

Honestly I've been wondering about going slightly bigger in the rear just to try it out...I just hate trying to match the rear holes when installing the sway bar



Post Title: Re: (aw614)
Posted by: Xian at 4:19 PM 6/21/2016



Yup, I ran the 26mm Mugen bar with a completely DS setup (Z1 Star Spec) and then later ran the ASR with stock springs and 15x8's (205 Rival). Neither setup was overly loose though both required you to be on top of the wheel and throttle.

This was the last event I did in the car ^^^. IIRC, it was the ASR bar, revalved and shortened Bilsteins, bumpstops from RESupension.com, and stock springs. Basically DS legal except the wider wheels. If I were doing a DS prep again, I'd do basically the same thing but with 71R's. How big is your current bar?



Post Title: Re: (Xian)
Posted by: aw614 at 7:55 PM 6/21/2016



stock rear 22mm bar, I've gotten used to being on the throttle on my current setup after initially not being used to it. I take it with the larger rear bar it will point and shoot a lot more? I just want to try something different with the rear, while still keeping the stockish suspension for now, I think it could rotate a tad more than what it currently does.

I've pondered getting the godspeed 25mm solid sway bar on ebay b/c its cheap just to try it out, but Im not sure on the measurements and how much stiffer it would be over the stock 22mm. I know Stephen from Team Integra is using it on his GSR.




Post Title: Re: (aw614)
Posted by: Xian at 4:38 AM 6/22/2016



It's not that it'll "point and shoot" so much as you can be on the throttle (to varying degrees) on corner entry vs. trail braking in. I think I started a thread a couple years ago where I ended up working out the relative stiffness of the different bars. IIRC, the 26mm solid is about the same rate as the smallest ASR (0.95 wall) in it's middle setting. The next size up with ASR (0.120) is slightly stiffer when adjusted to full soft than the 26mm solid bar. From that point up, the rates get pretty nutty. I think the 25mm solid (I ran a Cusco one on my 01 for a bit) was a little softer than the softest setting on the smallest ASR bar.

All the above options are quite a bit (double?) the stiffness of the 22mm bar. Don't get me wrong, I'm not knocking the 22mm bar... it's a great street bar but I preferred a larger one. The counterpoint to this is that Ed (Zygspeed), who sold me the 26mm Mugen, said that he damn near spun his car doing less than 50mph when he tried to run it. The point being that different setups are different, different applications are different, and different driver preferences are different. A big rear bar is worth trying but may necessitate other changes to the car/driver in order to get it to work for you.

I would definitely check out the Eibach RSB. It is ~22mm but with stronger steel and has three settings for stiffness. Oh and it is super affordable.

Might look into that bar

Got some more data on the 71R yesterday

Overall a great day. On the sunny and hot side though (mid 80s) so I was curious how hot and slippery these would get. I found in the 3rd session Reviewing logs and uploading vids as I speak.

Started cold pressures out at 32F, 34R before first session. Didnt push the car too hard but tires felt pretty good. Temps at the end of the session were up to where they normally get, around 40F and 38R.

For the start of the 2nd session, pressures were still high from the first session, so I lowered them back down to 32/34 again. Car still felt really good and had a nice battle with a Carrera S (I won ). Then VTEC started cutting in and out so I had to back way off the rest of the session. Pressures at the end of the session were around 37 all around.

3rd session, pressures were still high from previous session, so I lowered them again to 30F and 33R. Also added more oil and had no more VTEC hiccups. The car was very planted and set my fastest lap time of the day during this session. Then I got a little aggressive through one of the more slippery turns, pushed hard to the outside, dropped two tires and caught the edge of the track and it spun me out. Kept my foot in the gas hoping the tires would catch (you could hear them trying) but it didnt happen. Probably more of me over driving the turn than the tires losing grip. Went through pit lane to check the car over, all good, and back out I went.

Overall the car felt very similar to previous days but with maybe a little more grip up front to where I could feel the tires working a little more. Rotation felt about the same though so not sure what my next move will be. Maybe try more pressure in the rear, or pick up a RSB and play with that, or both. Regardless of my rotation tweaking, these tires are brilliant, and so is the car. Ive never had a Porshe driver come over to me and say hey, Im the guy in the Porsche you passed. Gotta like that. I havent totaled up the mileage on these tires yet (mostly track, with a couple hundred street when I was lazy and didnt feel like changing back at the end of the day) but so far they seem to be holding up well.

But for now the first thing I need are seats. These stock seats are KILLING ME lol. Re-adjusting my body and seat belt after every turn is getting old.



Post Title: Re: (RTW DC2R)
Posted by: Xian at 4:04 AM 6/24/2016



Sounds like another good time out.

On the seat thing, are you locking the seatbelt tight across you before you go on track? I used to have a routine... slide the seat back part way, tighten the belt across my lap, push my torso back in the seat, reach up with my hand and give the belt a sharp tug to lock it, lean into the locked belt, and then pull myself forward with my feet (under the pedals). Seemed to do a solid job of locking me in place and is cheap.

The black bars JHP sells are extremely old and do not work with ITR LCAs. The red ones that you've most likely have seen will work with the ITR LCAs but isn't a perfect fit on the ITR.

The spacing between the swaybar bushings is slightly different from ITR to non-ITR and EG chassis. We have a pressed on ring bushing stop that will be almost an inch from the bushing on ITR.

The bar can also be bolted right up to the subframe on the ITR. The black spacers we include are for non-ITR chassis that require a bit of spacing to clear the bushing stop ring.

Not super useful to anyone at the moment (no ITR sizes currently) but he new Nexen is supposed to be the sister-tire to the next gen RS3. Early reports is that it's about 0.75 seconds slower than the 71R on a 69 second course. Supposed to have really good wear though so it may end up being a great track day tire. It's cheap as hell too...

http://www.tirerack.com/tires/...Sizes

Sooooooo... bringing this back up. I drove the new Nexen Sunday at a Dixie event (grippy concrete site). I've gotta say that I'm impressed with the tire. My thoughts of their 255/40 17 compared to the 265/35 18 RE71R I've been running this season:

Turn in doesn't feel as sharp and the tire generally feels less "racey".
A fair bit more tire noise.
Seemed to take heat just fine... At least comparable to the RE71.
Appears to run wide. The 255 is wider than the 265 RE71R and equally as wide as the 275 Bridgestone (all on 9.5" wide wheels).
Initial wear appears good.

I'll go out on a limb and say ithat, for this size comparison, there's maybe a couple tenths between the two. I ran the Nexen for 3 runs in the am and the Bridgestone for 3 runs in the pm. I didn't get a chance to do a "real" ire test where I went back and bracketed my afternoon runs with the Nexen. As a result, I don't know if my afternoon runs were faster because I figured out one section was faster than I thought, the track rubbered in, or the Nexens are genuinely off the pace of the Bridgestone. The timed difference between the 2 was almost exactly 1 second on a 52-53 second course BUT that entire second was made up in the last 1/3rd of the course where, when I compared data and video, I simply drove a better line and then carried more speed through a big sweeper and fast offsets section. Before that point the 2 times were on top of each other. My fast time on the Bridgestones was good enough for 2nd in Pro (0.25 out of 1st) and 4th in PAX (0.4 out of 1st) and sandwiched in with the faster guys.

I'll keep running these for a bit locally and see how they do but, so far, in pretty impressed by the product. Given that they've got a 225/45 15 out now that appears to be a solid 1" wider than the RE71R, these may be worth checking out.

Video of the 2 runs:

Thanks for the feedback Christian

Actually noticed the Nexens yesterday when I was browsing around Tirerack. Im tempted to try out the 225/45 on my 15x7 wheel. I know most people say it will feel like shit but Im wondering how much of that is personal preference. Couldnt I just run a bit more air pressure if it feels too sloppy?

The Treadwidth difference between the 205/50 71R and Nexen 225/45 is 1.1". The tire weight is identical, but the Nexen has .1 less diameter (more acceleration! lol).

FYI the 71R is in stock on Tirerack and there is a $70 prepaid card offer valid through 8/21/16





Post Title: Re: (RTW DC2R)

Just my $0.02 but I wouldn't run a 225 on a 7" wide wheel unless I was doing it to deal with heat management issues and accepted going into things that wear and feel is gonna suck. The deal with pinching a tire is that, as you say, more pressure sorta fixes the issue BUT you end up compromising the contact patch with the extra pressure as well as still having a setup that feels about as satisfying as a loose a$$hole.

I tried a 205 Rival on a 15x6 and it was simply awful. If I ran enough pressure to keep the tire from rolling over, I ended up with wheelspin problems (hooray over-inflation!). Running the same 205 on a 15x7 fixed things up. That same 205 did even better on a 15x8. A 225 did fine on a 15x8 but was better on a 15x9. I'm sure you could get a 225 onto a 15x7 but I wouldn't do it on a front wheel drive, front heavy application.

They seem like a decent tire and should probably be able to run pretty close to the Bridgestone (because 225 vs 205) but you'll want to run them on 15x8's.

Nice! Their road hazard is pretty dang good. Had to make a claim earlier this year for a 265/35 18 that got a screw in it after less than 20 runs. Easy and fast claim process.

Christian - Slightly off topic, but whats you thoughts on 225 vs 205 RR's for HondaChallenge? 15x7. 2250 vs. 2500lb car.

I've got zero first hand experience with the RR... That being said, with an R-comp the answer is typically as much tire as you can fit (even when wheel width limited). I'd look to run a 225/205 stagger in an effort to help the front/rear come up to temp at the same rate.

Interesting read regarding pressures. Based on this info I am probably still running too much pressure in my 71Rs. My hot pressures were 35-36 after my last session at my last event so gonna go lower next time out.

Skimming that article, seems to me like you're in the right range for a street tire on a DC. Or are you running a really light EF?

DC2R. After looking at their little chart and looking at my tires it looks like I can still come down a psi or two. We'll see how it plays out.

Was at the track yesterday and didnt have time to put my track wheels on so I went out on Azenis and stock wheels. They performed surprisingly well and are a little more forgiving than the 71Rs. I actually kind of liked how the Azenis felt but it was my first time on that track and I would have loved to do back to back session comparison. Just didnt have the time.

Back to the tire size discussion, how much different do you think 225s would feel on a 15x7 wheel compared to running 205 Azenis on the stock 15x6 wheel?

I wouldn't use their numbers for much aside from a comparison of relative pressures... a Hoosier is substantially different from a street tire and how they behave at a given pressure. With their super stiff sidewall, you can run quite a bit less pressure and still have a happy tire. Another thing that I've heard is that back to back testing has shown that there's a decent middle ground of pressure where performance and grip doesn't change but wear and wear patterns does. Point being, going to the super low end of things may not improve performance but could negatively impact wear.

As to the 225 street tire on a 15x7, for the billionth time... I wouldn't do it. I don't like the feel of a loose butthole. If this was a Hoosier, I'd do it without a second thought.

I agree with Christian about running 225's on a 15x7 wheel. While 225 tire will absorb heat better and potentially have a large operating window, it's not worth the mushy feeling you'll experience. A 205 on a 15x7 is much crisper, is easy to toss around and in my experience seems to promote a better driving line and technique. That being said, a 15x7.5 or 15x8 is a different matter, and especially if you're talking real tires "slicks".

Oh yeah and a 205 on a 15x8 is a different story as well. Possibly OK for very VERY short stints and average driving, but anything aggressive or longer in duration will be no bueno.

15x6 = 195 or 205 regular*, R comp* or slick*
15x6.5 = 205 regular, R comp or slick
15x7 = 205 regular, R comp or slick**
15x7.5 = 205-225 regular***, R comp*** or slick***
15x8 = 225 regular, R comp or slick
*expect slightly less feel and nimbleness with a 205 but will have a slightly larger operating window and more effective grip
**if using a slick, a 205 or 225 size is ok, however, 225 is preferred
***if using a regular or R comp either a 205 or 225 will work, although expect slightly less feel with a 225 but will have a slightly larger operating window. If using a slick, a 225 is preferred.

Sooooooo... bringing this back up. I drove the new Nexen Sunday at a Dixie event (grippy concrete site). I've gotta say that I'm impressed with the tire. My thoughts of their 255/40 17 compared to the 265/35 18 RE71R I've been running this season:

Turn in doesn't feel as sharp and the tire generally feels less "racey".
A fair bit more tire noise.
Seemed to take heat just fine... At least comparable to the RE71.
Appears to run wide. The 255 is wider than the 265 RE71R and equally as wide as the 275 Bridgestone (all on 9.5" wide wheels).
Initial wear appears good.

I'll go out on a limb and say ithat, for this size comparison, there's maybe a couple tenths between the two. I ran the Nexen for 3 runs in the am and the Bridgestone for 3 runs in the pm. I didn't get a chance to do a "real" ire test where I went back and bracketed my afternoon runs with the Nexen. As a result, I don't know if my afternoon runs were faster because I figured out one section was faster than I thought, the track rubbered in, or the Nexens are genuinely off the pace of the Bridgestone. The timed difference between the 2 was almost exactly 1 second on a 52-53 second course BUT that entire second was made up in the last 1/3rd of the course where, when I compared data and video, I simply drove a better line and then carried more speed through a big sweeper and fast offsets section. Before that point the 2 times were on top of each other. My fast time on the Bridgestones was good enough for 2nd in Pro (0.25 out of 1st) and 4th in PAX (0.4 out of 1st) and sandwiched in with the faster guys.

I'll keep running these for a bit locally and see how they do but, so far, in pretty impressed by the product. Given that they've got a 225/45 15 out now that appears to be a solid 1" wider than the RE71R, these may be worth checking out.

Video of the 2 runs:

https://youtu.be/uSNJf14UGoE

Circling back with a more thorough review... made some minor setup tweaks from the last event (above) and took 0.7-0.8* of camber out of the rear as well as ~0.2* out of the front (adjustments based on tire wear/rollover as well as balance).

The result was getting the car back into the sweet spot handling-wise where it was "too loose" on the first run. A couple clicks softer in low-speed compression coupled with a 3# tire pressure drop fixed things up. With the setup changes, the new tires are really damn good. The initial softer turn-in and noise appears to have gone away. This could be setup or it could be getting a heat cycle into the tires as well as wearing down some of the "ghost tread". Wear and heat tolerance still appears very good. The tire is good at multi-tasking, braking, and puts down power well... turn-in is still a little softer than the 71R but it doesn't slow you down.

My co-driver and I ended up 1 & 2 in Pro, overall PAX, and overall Raw time and were still figuring out how much farther the tire could be pushed on each run. My $0.02 at this point is that tire is pretty damn close to the Rival-S and RE71R. Given the 225 sizing, I wouldn't hesitate to give them a try if you're looking for track rubber. I don't know how well they'll do pinched but I'd say they're closer to the 71R than the Rival-S when it comes to sidewall construction. Only sucky thing is that their 225/45 15 isn't particularly cheap so you're not going to save a ton of cash running these unless it's due to better wear.

PS
We were seeing just shy of 1.2g peak steady state lateral and up to 1.5g combined lateral and longitudinal (older, asphalt runway). I'd expect concrete #'s to be a little higher.

I can probably google this but figure Ill ask here since were talking about tires.

For directional tires like the 71R, can I run them backwards assuming a dry track? Noticed today the outside of my left side tires are wearing more than the right and Id like to try to even them out. Probably due to clockwise tracks and mostly right hand turns. I dont see why not unless its raining.



Post Title: Re: (RTW DC2R)
Posted by: coolhandluke at 3:06 PM 8/21/2016



Negative, a directional tire will wear irregularly when run backwards. You could extend the life by having the tires swapped from side to side but there is a cost there unless you have a tire shop hookup.

Posted by: Xian at 4:35 AM 8/22/2016

Sooooo... take this with a grain of salt because it's not apples to apples. I know some folks will run tires "backwards" for autox to even out the wear patterns. The statement about rain is 100% spot on but I haven't heard of irregular wear being an issue (though intellectually it makes sense that the tread blocks wouldn't respond to loads in the same way if they were leading with the "tip" vs. a broader surface). It may be a case that the duration of use for autox (3-6 runs) is enough to balance wear without accelerating it when the tire is run backwards? I dunno... personally, by the time they got worn enough that I would be considering something like this, they were worn enough that I'd flip them on the wheel (and pay $80 for dismount/mount service).



Post Title: Re: (Xian)

Thanks for the extra info. I might just try it anyway and see how it feels and/or looks after a session on track. The main track I have run this year is extremely hard on left side tires (NJMP Thunderbolt). The only left hand turn on this track is slow without much load on the tires so it makes sense the wear I am seeing. The outside section adjacent to the sidewall is almost worn through the tread blocks. The ride side isnt even close to that bad. Pocono this week which isnt as hard on the left side so I can probably leave them alone. But might swap before next NJMP event. If nothing else I will flip the tires.

Would more air pressure help save the outer edge of the tire to help keep the tire from rolling over so much towards the sidewall?

We usually run the outside loop(without the turn 2 and 3 inner sections)

More pressure won't hurt but it still may not be enough to fix the shoulder wear. If you do try them flipped (either on the car or on the wheel), expect it to take a little bit for the tread peaks to wear down from being leaned on the opposite direction.

I also took the time to measure their tread depth... appears that the center ribs are 3/32nds deeper than the shoulders. Should mean that this tire is gonna get pretty fast toward the end of it's life if it doesn't cycle out first.

Finally going to pull the trigger on some new tires for my stock R but a little undecided.

Seems to me saving the $100 buts makes a little more sense, especially for a stock caR. Any thoughts? Not ruling out an eventual track session.

Heads up, both the BFG G-Force Sport Comp 2's & Firestone Indy 500 are in a different tire category, Ultra High Performance Summer. I would compare the two to each other, but not to tires in this thread. If you don't plan to track I wouldn't bother spending coin on tires in the Extreme Performance Summer category. If you pursue tires in the Extreme Performance Summer category check out the reviews here. Many like Xian have posted excellent reviews and feedback. The 615k's would be towards the bottom of the list- they are old technology these days.

Gotcha --- I figured you guys would help me out with advice even though the 2 candidates aren't in the title category. I would still like to eventually get some track time in since I am about 45mins from NJMP. I will read back through some of the pages and hopefully make my mind up! Thanks again.

Forgive my tone, I get on a soap box when comparing tires from different categories. I'm happy to help.

You can track on both tire categories, but the EPS will offer max dry grip. Are you on stock wheels or aftermarket? If aftermarket, what size?

No worries dude! I'm on stock wheels right now with no near term plans to upgrade to anything different. I think I should just stick with the Comp 2's but jumping up a category to something like the Re71r is really tempting.... and would probably give me more motivation to get out to some track events etc.

FYI I ran the 71R flipped yesterday. Took it easy the first session to feel them out. I expected them to feel like crap but by the end of the day they felt pretty close to normal. If anything it almost felt like my car wanted to rotate a little easier which I liked until it bit me in the ass late in the day. It was a little cooler temps outside so maybe they werent getting quite as sticky as usual.

Good info thanks ^ ! What tire pressures were you running when hot?

I ran 16x6.5 with 205/45/16 RE71R for the first time today at autoX. I ended up hot 36F and 33R. All stock suspension.

The fronts were rolling over about half way down the shoulder to the start of the sidewall but rears didn't. I wasn't sure about lowering the pressure more in the rear as the car felt balanced despite not using the entire tread.

Xian: Big thanks for the seat belt trick posted a few pages back! I had no problems with sliding around in the seat after locking the shoulder belt.

Im sure autox doesnt build as much heat as a 20 min track session so keep that in mind. But I seem to like the fronts to be around 36-37 hot (30 cold), that seems to be about the range most of the contact patch is used before it feels sloppy and mushy. I run slightly higher cold psi in the rear though (33) since temps dont come up quite as much as the fronts and it seems to help me with rotation. Hot rears are usually around 38-39 for me. Depends on track/weather of course.

Im on PIC R3 with 10/12k springs, stock bars, and about -3* front and -1.5* rear camber.



Post Title:
Posted by: touringteg at 6:17 AM 9/19/2016



Very true. It was a mild day at about 65F as well so temps stayed pretty low. I checked my cold pressures and it is 32F and 28R. (36F and 33R hot).

When I dropped the rears for my last two runs from 35R to 33R hot to see if I could get more roll over things got sloppy and I was unable to match my best run of the day (run 6 of 9).

I'll up my rear pressure because it seem to provide better response and a faster time.

Thanks for the info

As a side note I checked what other tires people were running and at least half of the field (small turn out of 23 racers) was running RE71R. Very popular tire for autoX in Canada. Hankook RS3, Rivals, Kumho V710 all have to be ordered from the US where as we can get RE71R or RE11 from Costco with ease.

In new, news the Maxxis VR-1 is supposed to be available in a 225/45 late this year or early next year. That'll give them a 205, 225, and 245 15" option. Really cool to see the support for the smaller tire diameters! Also some news that Conti is reworking their DW and renaming it "Sport". Good news here is that dry weather performance is supposed to match the Michelin PSS and they'll be offering a 205/50 15. This should be a pretty awesome tire choice for folks who need a little better street or wet manners than they can get from the Extreme Performance category offerings.

Post Title: Re: (aw614)

Some anecdotal evidence that the Nexen doesn't do well pinched or without enough camber. Folks with Minis and FoRS are managing to burn off the outside shoulder of the tire. Granted those cars are especially tough on tires but it's still kinda crappy.

Rumor mill- word on the street is that BFG is considering whether or not to build a Rival-S in 245/35 15 like Maxxis is offering. *IF* they did this, it'd be a pretty badass offering if you can get it under the front fenders.



Post Title: Re: (Xian)
Posted by: RTW DC2R at 8:42 AM 11/28/2016



Speaking of shoulder wear, I pretty much burned through my 71Rs on the outside shoulders as well. Still plenty of meat in the middle but the shoulders are worn smooth. I noticed it a few events ago. And by day 2 at Expo I was slipping and sliding all over the place. Im guessing its from running low-ish tire pressures. You can see it pretty good below on the right side tires. They have about 550-600 track miles on them after Expo 16 and less than 200 street miles.





Post Title: Re: (RTW DC2R)
Posted by: Xian at 10:47 AM 11/28/2016



Yup, based on the pic, I'd say you need more camber and/or wider wheels. Higher pressure could work also but that stands a good chance of making the front of the car sorta pushy (so you'd need to bump rear pressures/spring/bar to compensate).

FWIW, the tire itself, is good to the cords. You may have been pushing the tire harder toward the end of Day 2 or ambient temp could have been enough to make it start to go off. You can certainly overheat that tire if you lean hard enough on it.

This tire was still sticky/good...

Nice. If $$$ allows I may switch to R comps for next season. But if I can get a few more miles out of these I might run them as far as they will go before switching. Any idea how many miles are on the tires in your pic? Mine seem to be wearing better than I expected except for the shoulder area.

I am definitely going to be making changes to suspension in the off season, including full bushing refresh, higher rates, maybe a rear bar upgrade, and maybe a little more camber. Also might want a fugen wing or similar for a little more stability/grip during high speed cornering.

Refreshing the old/worn bushings are the car with new OEM rubber/similar will definitely tighten up the car. I would definitely run the main pieces before switching to rcomps.

Those were on a buddy's chumpcar and had ~24 hours on them. Just pointing out that you can run them until they cord without a performance drop off (assuming they don't heat cycle out beforehand and assuming wet performance isn't a big deal).

I don't remember the specifics of your setup but some more front rate and some more rear bar is often a good combination. Flattens the car out but helps keep a similar balance. Agreed with your (and Ryan's) thought about looking at bushings. IIRC, Ryan did a write-up on using a blend of OE and spherical. Sounds like a good combination that worked well. Also, if you're getting Kingpin stuff (and I suggest that you do), do it *NOW*... it appears Chris may be winding down his business very soon.

[quote=Xian]Yup, based on the pic, I'd say you need more camber and/or wider wheels. Higher pressure could work also but that stands a good chance of making the front of the car sorta pushy (so you'd need to bump rear pressures/spring/bar to compensate).

Xian, I get how inncreased pressure/more camber could help even wear but I don't understand why a wider rim would. I would thing a smaller rim would "round out" the tire similar to over inflating I have a very similar was pattern with my re-11s. Outside is smooth but inside block has good tread. (205 re11 on 6.5 inch wheels) I don't have enough camber though.

Wear like this?

This was on my old RE-11A on the stock 15x6 wheels and on stock UCA, I was running 40 psi front and 45 psi rear. Strangely enough they were still grippy and lasted a few more events with my friend and his e30. Though I think his e30 needed much more camber...

Im on RE71r now with -2 degrees of camber, but still on 15x6 wheels. But I don't think it's going to wear as uneven as that. They are wearing a lot more even now with probably 80 or so runs on them.

40 and 45psi are pretty high, no? My hot temps with the 71R are nowhere near that. Might be partially why I have the shoulder wear though and likely need more camber all around.



Post Title: Re: (RTW DC2R)
Posted by: aw614 at 9:28 AM 11/30/2016

looking back I believe so, that was first foray into 200 tw tires. Now I typically run 35 psi up front and 35-40 in the rear...

A wider wheel keeps the tire from rolling over onto the outside shoulder as much. Pinching a tire lets it roll/shift on the wheel more and concentrates the load/wear onto the outer shoulders of the tire.

Running a really high pressure reduces rollover and helps even out wear at the expense (usually) of lower grip.

Oh, and additional rumor mill stuff:

The new Falken 615K may share the same or a similar compound to what was used on the Z2 SS. Apparently Dunlop and Falken have some corporate level ownership ties that may have let them leverage the Z2 technology. Take this one with a grain of salt.

A known fast guy/tire tester tried out the new Federal RSRR and seems to think it's "in the neighborhood" of the RE71R and Rival-S. This is a single data point but a pretty good one. Not sure what their sizing, availability, and pricing looks like.



Post Title: Re: (Xian)
Posted by: aw614 at 6:22 AM 12/1/2016



From the sizes it looks like the federal come in a honda friendly 205/50/15 so that's a good thing for most.

When I had the Z2 SS, i noticed they were made in Japan, I take it those were probably related to summitomo dunlops rather than goodyear so it would make sense it was related to the rt615k. It does seem like the falkens use the same name, but unless you keep up on tire news, you would never know it was a different compound revision or not...



Post Title: Re: (aw614)

FWIW, looks like I missed the correct nomenclature... it's the 615K+



Post Title: Re: (Xian)
Posted by: coolhandluke at 6:15 PM 12/4/2016

The Falken 615K+ and Federal bits are intriguing. Good tire options are always a good thing. I suspect I should update the OP with new tire/size options over break.



Post Title: Re: (coolhandluke)

Not my pics, not my info but saw this elsewhere... new Hankook RS4 coming with some very friendly sizes:

Any word on release date?



Post Title: Re: (coolhandluke)
Posted by: Xian at 11:49 AM 12/12/2016

Nope, I haven't seen or heard anything on it... I'd expect early 2017 so they can meet the SCCA tire eligibility restrictions.

Edit:
The revised BFG should be out around the same time *and* their 245 15 has shown up on their sizing list...

And a new ZIII is on the way... Feb 2017 but not sure what that means for the US.

I'm pretty excited about the 245/40/15 from BFG, I think you could fit it under stock fenders with 3-3.5* of camber. I've seen a 255/40/17 under a stock JDM front with that kind of camber, on a 17x9.

I'm also excited about the 615K+, can't wait to see more. I really like the 615K that are currently on my R over the Kuhmo's it had on it prior. I'd like to see more options in the 225/45/16 size, I've got a set of 16x7.5 +42 TE37's that need a set of tires for this summer.

And the RS4 is now listed on TireRack... I'd expect it to be out soonish.



Post Title: Re: (Xian)
Posted by: RTW DC2R at 5:26 AM 12/30/2016

Any idea how these might compare to the 71R? They have a stock wheel tire size but dont know if that would work on my 15x7 track wheels? 71R are also cheaper in a 205/50.

$127/per. Delivery date is soon. These will likely be my next set of tires.



Post Title: Re: (coolhandluke)

Zero data on how the RS4 will perform. I did see a post from a guy who works at TR that they're expecting their first shipment of them in March. Should be ~20 sizes available at initial release. My suggestion would be to buy them now and get your tires reserved if these are what you want. I wouldn't be super surprised to see the popular sizes sold out before the first shipment arrives...



Post Title: Re: (Xian)
Posted by: coolhandluke at 9:37 AM 12/31/2016

True, I dont need the tires yet but at some point I may want to stop staring at my wall art and drive them.



Post Title: Re: (coolhandluke)
Posted by: Xian at 3:22 AM 1/1/2017

Lol!

Looks like TR took them back down from the website... I've gotta think that they were getting plenty of timing related questions so it was easier to pull them than it was to keep answering inquiries.



Post Title: Re: (Xian)
Posted by: coolhandluke at 12:53 PM 1/1/2017



Yup, they are already pulled. It helps (temporarily) save me $500 anyway.



Post Title: Re: (coolhandluke)
Posted by: Xian at 5:46 AM 1/4/2017

FWIW, TireRack is accepting phoned in orders for both the RS4 and new Rival-S... including the 245/40 15 sizes.

Was just reading that Nexen has a new, new tire coming in potentially the next couple months. They used a couple autocross hot shoes in part of the design/testing so I'm hopeful the new tire is a decent improvement over an already good option.

The new, new Nexen is on their site. Should start hitting retailers pretty soon I suspect:

Looks like tire rack has the new conti tire up at 91 dollars a tire for 205/5015. Its tempting to get those for regular street driving and have RE71rs on my other wheels.

I need to update the original post with these new tire options.
