whats the best size tire for rims that measure 9.5 and 10.5 wide 18 inches in diameter? their z06 rims

i live in pennsylvania and the roads here are very unforgiving and bumpy, and im just trying to find out what size tire would be best suited to handle the rough and bumpy roads around here...thanks

275-35 and if you have the money 315-30. If not do a 295-35

id also like to lower it, but in PA I bottom out everwhere pretty bad so i really cant lower it, plus im tryin to fill in the space of the fender, 35's jus looked too skinny

you can go thicker, it will just throw off your speedo a little. Just be sure the overall tire diameters are not more than about 1" different. It will **** of your ABS (if you have it). If you dont have ABS or TCS, go crazy with tire diameter differences. but again your speedo will just be off.

Stock tire Diameter = 25.66"
275-35-18 = 25.57"
295-35-18 = 26.13"
315-35-18 = 26.68"
If you went larger, say for instance a 40 series:
275-40-18 = 26.66"
295-40-18 = 27.29"
315-40-18 = 27.92" (way too damn tall)
