I will be trading rims with my bro. He has 17x9.5 with 245/40/17 up fronts and 18x9.5 with 275's out back. Will I have any issues as far ar driveibilty, braking etc. with this combo? I have the factory 10 spokes with 275's all around. My car 00 vert. SS bro's 91 Z28.

I take it they are not OEM? OEM's are 18x10.5 at the rear (I run them). As long as the offset is correct, you should have no problems. What is the exact rear tire size? (you may want to make sure overall tire diameters are close, so your ABS doesn't complain)

The front tires are a little too skinny for the wide of a rim. But I've been running 17x9.5" w/275s on all 4s for the last couple years. Haven't had any issues to speak of

Ok thanks so I should run 275 up front. The back will be 285's will that be a problem?

Turo

285 is the widest I would run on a 9.5" wide wheel so it should be fine.

What do u mean by overall tire diameter?

Turo

For example, a 285/40/18 is taller than say a 285/35/18. You want your front and rear tires to be close in height to each other so your ABS doesn't go out of whack. As long as they're close you're ok. My front and rears are about 0.5" apart (i think?) and I have no trouble. Anymore than that may be pushing it.

OK thanks man. We will be swapping Wed. night and i will let u know how it goes.

Swap has been done and it looks good. Thanks to all who helped. I went with 245/45/17 up front and 285/35/18 out back. I will get 275's later as I traded my silver 10 spokes with tires for his chrome c5 zo6's.

Glad I could help. I went through the same thing about a year ago whe I installed OEM Z06's on my car (using 2 different tire sizes).

What psi r u using in both front and back?

Turo

iTrader: (23)

I can't remember off the top of my head, but I want to say it was around 35 or so? Whatever was recommended by the manufacturer. These are daily driver wheels/tires so I don't worry abould lowering the psi for better traction.

Ok because I got them at 32
