No. The claims that the RE01R has a soft sidewall are way overblown. All of these come from people who race and are comparing them to tires with very, very stiff sidewalls. The RE01R is still stiffer than just about any other street tire you're likely to find.

It's it stiffer than the stock a046? Probably not. It definitely rides better, but doesn't give much away on track.

EDIT: Just as a point of reference, I've been through three sets this summer racing. They sticker better than the stocker, come in larger sizes, and even last longer.

 

well,
i'm on snow tires right now, so my perception of how they handle as compared to a-046 will be out of whack. they'll feel stiffer than the dunlop sp m3 blah blah blahs. i'm ready to rally the crap out of some new bridgestones!

 

initial verdict:
they are dope.

very heavy at 28 lbs.
in case anyone wants to know: stock mr bbs weigh roughly 16 lbs. on a bathroom scale with me on it to increase accuracy
the combo weighs in at 44 lbs.
thats about 3 lbs heavier than the stock combo which is the same difference listed on tire rack!
i've got partial buyers remorse already, but they do stick like crazy.
guess i'll need to burn off some of that 5/16" tread!

 

3 lbs... bah... just wait til they were down a bit, take a little weight off the gut, ditch the wiper fluid, couple gallons less gas, it's all the same

 

3 lbs. of unsprung and rotating mass. they stick real nice though .

 

While the REO1r's are a bit heavy, they stick pretty damn well.


What sold me was the massive impact it had on road noise. With as many noises as my Evo makes, the last added thing that I needed was road noise.

 

I ran the **** out of these at the Nurburgring and I have no complaints. After they were heat cycled on the first pass, they got super sticky the second and third run.

Gooey, stiff and great response. I have no complaints, and my lap times got faster each run. (That could be due to me finding the lines a bit better as well)

I love mine, and I'll buy another set when these are done. They arent full race sticky, but they are great once they get heated a bit.

 

Ok, i've done a lot of research and I've finally decided on these Re-01r's. My question is how big can I go on the stock 17" MR rims? This will be on a stock height MR without any suspension mods. This car will be my daily summer driver with autocross duty (an 8 event season).

The 255/40's fit on the stock tire without clearance or wheel well issues right? is this the biggest (widest) tire i can run? Also, what about the height (40 vs. 45)? Will a higher height give more roll over? Anything else I need to take into consideration?

I'm basically looking to get the best street tires for autocross. Thanks for the help!

 

245 40 17 or 245 40 17
to run a 255 u need wider wheel

 

well, 255 45 17 are generally considered the limit as far as i have gathered. the sidewall profile takes on a bubble shape rather than a trapezoidal (preferable) shape. i don't race and have very little experience with performance tires in general. 245 45 are taller than stock IIRC, 245 40 are smaller, and 255 40 are also a bit smaller but larger than the 245 40.

i run 255 40 without interference on bumps and turns with 3/4" drop and no spacers on stock rims. and these are generally considered the max size that i have read about realistically running on stock rims.

so your choices to my knowledge are:
taller than stock?
shorter than stock?
similar height to stock?
is wider better?
does unsprung weight matter to you?
what will look cooler?

i'm starting to think that the stock size would rock with a sticky compound tire like this (a little lighter) or a 245 40 (if you don't mind running higher rpms).
i do really like my 255s for the rpm and machismo factor.

i am no expert


i suppose if you want to autocross, rpms, trapezoidal shape and low unsprung weight are your friends and you will want 245 40 like previously suggested above.

 

I don't see any reason using 255 series RE01Rs. STU does not allow it and the rest of the class you will need R-compound to be just even with other cars. 245 is the maximum width for STU.

If you decided to run STU, there is really no measurable difference between aspect ratio of 40 or 45 in terms of sidewall stiffness. If you run on big courses with longer straights, run 45s; if you are on smaller course where you never hit 2nd gear rev-limiter, use 40s.

If you enter AS class 245 series tires is probably the biggest you want on those rims.

If you want to be very competitive in STU, shave your RE01R's to 4/32th and use it for autox only. Daily driving and autox on the same set will probably not last the whole season. If you are doing autox for fun, then RE01s are fine and no shaving is necessary. You can even run your Stock Neova's and get decent results.

If you are running AS, get some V710 Kuhmos or Hoosier A6s. You will get killed running RE01Rs in AS vs the R-compounds. JMHO.

BTW, my co-driver and I burned through 3 sets of RE01Rs last season and we are still not convinced that RE01Rs are the best tires for STU. They are cheaper the Yoko Neovas and we think they are better than Azenis. But I believe all highly placed STU cars in this years' Nationals all ran Yokohamas. It seems RE01Rs perform really well in lighter cars, but I think the verdict is still out on STU.

When you get a chance, really read through the STU/A Stock/SM/BSP prep thread in the forum. You will find most of the tire setup questions answered in those threads. Some of those guys are the fastest autox guys in the country and their opinions are well respected. Hope this helps.

 

Fixed that for you. You'll win some local events if you don't have any national-level drivers, but if you run into a well driven Z0K, S2000, or C4, you'll get smoked. STU ($), BSP ($$$$$), or SM ($$$$$$$$$$$$$$$$) are the classes the Evo shines in.

 

Thanks for the help!

And yeah, i completely forgot that the maximum allowed tire width for the STU class is 245. And even though i autocross the whole season, I don't have the time or commitment to become extremely competitive. So any R-compound classes or AS classes are out of the question. I have a lot more learning to do anyways.

So I think I'll just stick with the 245/40's without shaving them since they will serve double duty as a daily driver.

 

im lookin to pick up these tires soon do any of you guys know what would be the best size to go with for a stock bbs wheel for dd and occasional auto-x between the 245/40/17 or the 255/40/17

 

245/45 is a good option also. I think it's a little cheaper and you get a little more top speed in second gear. Plus it fills the tire well a little more and I personally think it looks better. Good luck!
