Anyone use Toyo proxy R888?
 

Thinking about putting a set of 275/40/17 & 305/35/18 R888 on my z06 stock wheels. Any one run this set up? I have used tripe eights before on my isf but didn't now if there's a better choice for a weekend track Z.

That or NT01 in the same sizes if you want a R comp. More street tire oriented your options are 275/295 NT05 or 255/285 RS3.

That is the combo I'm running. Love it!

^ Same here. Great setup.

Had these sizes ony car when i originally bought it. Great handling daily driving.

Installed a set and ran 2 track days at PIR, they are a super tire. Mine provided better grip at 36 psi than the Toyo recommended 32.

Oooops, guess the file is a tad large, size does matter.

Good to know, I might try bumping it up to 36 psi. :thumbs:

How much of a bigger tire can the stock z06 wheels hold ?

All available Toyo R888's are in stock and ship FREE from PTS!

I don't know what size you're trying to fit, but both the 305/35-18 and 315/30-18 R888 are spec'd to fit on a 10.5" wheel

If you don't want the same diameter tires up front as out back, you'll have to choose your front tires carefully with the 25.5"-tall 315/30 (the 24.7" 245 or 25.1" 255/40-17, for example, should work fine with the TC/AH system)

I was going to replace my tires soon....and I don't know a damn thing about numbers in the rubber. So darn said he had stock z06 rims with 275 front and 305 rear. I didn't know stock z06 could hold that.

Typically you can bump up 1 or 2 sizes on the stock rims. The R888s are a good option for the street and track. The Nitto NTo1s have a bit more grip on track as far as I'm concerned, but have a shallower tread depth.

I'll be running these on my new rims...

running these in 295/30/19 front and 345/30/19 on my new wheel/brake/suspension setup to be completed this week :thumbsup:

If you look up your tire of interest on TireRack.com and go to the "Specs" tab, it will tell you the rim width range for every size

The 275/40-17|305/35-18 combo will fit fine on factory wheels

The 275-305 maintains factory ratio for the most part. What's happens to your speedo with the 315 in the rear?

It would run a hair high since those are a bit shorter than factory (as opposed to it running a couple MPH low as your car sits right now on the slightly taller tires), but you probably wouldn't want to run those with your 275/40 fronts; 255/40 would be a more appropriate height for that rear tire

I have a set on my car and other than being extremely noisy I like the way they drive and handle. Even in the rain they are pretty good

went through two sets last year auto crossing, a great tire!
