I would go with 265/35 - 295/30, that's what I'm getting for my new wheels that's 9.5/10.5, fits wheels the best, I think a 305 rear is too wide. You would want to get 11's if you want to run that wide with such a small sidewall.

I would personally go with 265/35 up front & 305/30 in the rear, but with Michelin Pilot Sport 2. This set up would work & look sexy.

I was thinking the 305 might be a little wide, but lots of people run the RE-11 I that width on 10.5" wheels. If I go with the 295, I may drop down to a 255 front to keep the overall diameters close to each other. The 265/305 setup is only .1" different overall front/rear, which is the same as stock. Tough to choose!

I am still leaning towards this size combo. I am pretty dead set on the AD08 R though after my research. It was down to those or the Toyo R888, but I don't think I'm ready for such a soft tire as the R888s. I'm looking for something nice and sticky to put the ~400+TQ to the ground. Have experience with the PS2s?

On a 10.5" wheel 305 is more than fine! Rule of thumb, don't exceed 20% tire to wheel width. 320 tire would be 20%.

305 is more than fine, but I'd go much bigger on the front. Keep the front and rear close to avoid understeer these cars already have.

Thank you :tiphat:

I was originally looking at 275s for the front, but saw the earlier post mentioning the possibility of fender damage with that size and a big bump or potholes. The roads are garbage here in Charlotte, so it concerned me.

I could see it happening with almost no camber, lowered, and a lot of low offset. But you're running the OEM wheel so offset isn't an issue. Not sure if you're lowered or not.

PS the OEM alignment numbers are garbage. Even if you are stock springs/coils I vote you get camber arms and get a bit more aggressive than stock. Even on the street I'd shoot for close to -2.0. You definitely shouldn't rub with that camber and factory wheels, lowered or not.

Makes sense. I'm factory height and have camber arms right now. I'll have to look into the 275 setup with a little more camber. Thanks for the input!

Track guys love a square setup. Everyone seems to be doing it. You could even go 285 in the front if you insist on 305 in the back.
