Tires -- narrow RE11 OR wide Pilot Super Sport?
 

I have been running RE-11's to all autox events this year. I also have new set of Michelin Pilot Super Sport's which I'm considering running but I wanted to get some opinions before the Match Tour this weekend.

I know the RE11s are supposed to have more grip, but with the size difference, will I even notice much?

Current autox rims: (from base model 370z, rim narrower than stock)

RE-11 (200 treadwear, running low on tread)
FR: 18x8 - 245/40R18
RR: 18x9 - 275/35R18

VS

My stock rims: (from sport package 370z)

Michelin Pilot Super Sport (300 treadwear, new 0 miles)
FR: 19x9 - 255/40R19
RR: 19x10 - 285/35R19

What do you guys think? Maybe I just need to switch em and test it.

I am under the impression the RE-11 runs a little wide and they definitely have stiffer sidewalls. You might have to run so much pressure in the PSS to keep them from rolling over on the sidewalls, that they have much less grip than the RE-11.

Honestly I'm interested to see what kind of feedback you get from people on this, because I think the PSS is nice and light and grippy as a road tire and will probably last more miles but the RE-11 is a bad-*** grip machine, although an older design.

Or yeah... Test it... Go on... :D

I don't think 10mm of extra rubber will even come close to compensating for the RE-11's superior grip.

Thanks. I'll throw them on tomorrow and see how it goes.

In for results. :)

I just noticed that the RE-11'S are low on tread. The tread depth isn't an issue on dry pavement, but if the compound has heat cycled out, they may no longer have superior grip.

I have picked up almost two seconds on a 60 second course when going from old heat-cycled tires to a fresh set of identical ones.

So the size difference shouldn't be enough to put the PSS in front, but heat cycles may put the RE-11's back.

I know someone that rolled PSS sidewall on the Dragon. They're not meant for track abuse. RE-11s on the other hand are designed to be a trackable street tire.

Now if you're comparing used RE-11s to brand new PSS, then the comparison might be closer. But I'm still going to say that the RE-11s will give you a much better track experience than PSS.

are you referencing me? lol because yea that def happened.

I then switched to 265/305 RE-11s on my OEM sport wheels and love them. so much grip. just now with tread just barely above the wear bar the RE-11s slip when leaving a stopped position hard.

actually ordering my next set today for zdayz and dragon runs.

;)

sadly either tirrack's website isn't working properly or my internet is messed up. either way i'm having issues trying to buy tires right now lol

My experience is that RE-11s run narrow. I ran them for half an autox season 3 years ago. They are by far the best wearing tires in comparison to the Rivals, R-S3s, and RE-71Rs I've destroyed. However, the others have them beat in terms of grip.

That pic.....are any of those sets mounted on wheels?

I'd run the PSS, but mostly because the inch wider wheels. If you want to be legal in Street/Stock you have to run stock width wheels.

Both options are way way back from the new Bridgestone RE71R and BFG Rival-S tires.

from what I've seen the RE-71's just want to tear themselves apart after a few runs though.

The wear is fine in my experience (SD Tour and ET Pro 2015 « J-Rho's '67 Camaro Z28 STX build ). If his car is stock camber in front, he'll probably want to flip them on the rims at some point to normalize wear on the outside front shoulder.

They would disqualify me for a narrower wheel?

This is a competitor policed sport - there is no technical inspection you have to "pass". So the answer is probably not, especially at a local event, or anywhere where you aren't keeping someone from a trophy. But it's not technically legal.

I'm going to the Match Tour at the national corvette museum this weekend, but I know at least one of the competitors and he'll be hard to beat. He's running ZII and others will probably have RE71 and such. Having said that, I'm in it to win it if I can.

Straight from the 2015 Solo rulebook. But as it's already been said, most people don't care unless you're actually competitive.

I got these Advan Racing GT 18" (white) (9" all-around) wheels coming in June (early June they said), I'm going with 275/35/18, but not 100% sold on which tires to go with (I might track the car 70/80% chance I will this year) and want to be confident in the most important component of the car, the tires.

Should I go with the Rival-S or the Re-11 ? Price is close so that doesn't really matter.

What you guys recommend wear/grip wise?

Feedback much appreciated.

PS: I don't mean to hi-jack the thread just thought it is a good place to ask.

I'm planning to get wheels/tires solely for autox soon. I'm leaning towards the RE-71R. But if you're going to daily drive with them, then you might want something different -- I've heard they wear more.

This brings up another question on TIRE SIZE. On stock width wheels (to stay in B Street class), what size is generally recommended for Autox? The car could use some extra grip in the front for sure, but I don't want to change the feel (e.g getting mushy) and I don't want the tires to bulge over the rim much because that doesn't look good. So A, B or C?

RE71
A -- Square
275/35R18 x 4

B -- Staggered #1
265/35R18
275/35R18

C -- Staggered #2
255/40R18
275/35R18

275 square is what I'd recommend amongst those choices.

If you were considering the BFG the 275 front 315 rear would be a choice but the car would probably push like crazy...

Just a warning, I ran the rival 285 all around at 39 psi. In about 25 runs the front corners where shredded. I'm waiting on tirerack who just picked the tires up for inspection to see what they say but I don't think our cars stock have enough camber for that tire

No, just chillin in a stack.

I'm on 275 RE-71R square right now. Looking forward to how they react at the Match Tour this weekend. I've run 285 square twice with RE-11s and R-S3s. 285s are pretty happy on the front 9in, and the rear 10in is obviously no problem. In between those two tire options, I ran 295 square Rivals. 295 up front was pretty fat, and with no camber, killed the shoulders after just one Match Tour at Wilmington. I'm interested to see how the Rival-S fairs for others.

Yes, absolutely at a National event. You must run stock width, so with Sport Pkg that's 9in front, 10in rear. Base model wheels do not qualify. Your only option is to run the Sport 19's, or use the +/-1in diameter rule and get some 18x9s and 18x10s. Otherwise you're going straight to ASP and better find some Hoosiers real quick.

Sorry...or STR with your base model wheels and 255 max wide tires.

Rival or Rival-S?

Tires -- narrow RE11 OR wide Pilot Super Sport?
 

I put my stock wheels back on with the pilot super sports and tested it tonight. They felt pretty grippy compared to what I was expecting. I think they actually would out corner the re11 since the PSS's are new. The re11s have some highway miles--not sure if that could affect anything. So for this weekend I'll be running the PSS's. I guess I'll see you there. Are you running in street?

Handling-wise, is there benefit to running a smaller sidewall only in the front so the car points downward some?

I'll find you in the morning in BS. We run in the 1st heat (street sweepers...uugh). There's no real advantage to smaller sidewalls....just have to play with pressures and make it happy.

Rival.. I have not used the rival S yet and not sure if I will with how the standard rival wore out
