I'm picking up some 17x9.5 for my 91 Z28 and just wanted to make sure to get the right tire size. I think you guys have suggested 245/45ZR17 on all for corners, just wanted to make sure. The car is all stock just wanting to make it look a little better and handle better but not rub the tires on turns.

 

4th gens have 275/40-17 on 9.5" rims that is what i would get in the rear. I would also get something like a 255/40-17 or 265/40-17 in the front. A 245 wide tire on a 9.5" rim is a little small, the tire will really be streched to fit.

 

i have 17x9.5 with yokohamas avs db series tires 275/40/zr 17 and i love these tires. Very good in rain and dry roads.
