225/35/18??? is this right
 

this guy said i need 225/35/18 on my new 18' 9.5 z06 rims for front) this dosent sound right souldnt it be more like 275/35/18 on the front?

225 is WAY to narrow. 275 is perfect for a 9.5 wheel

wherever it was that the guy said that, never go back again. he is a moron. 275 on a 9.5 is right like zack said

Not only is a 225/35-18 too narrow for a 9.5" rim, it is also too small in diameter..... about 1-1/2" smaller than the stock tire diameter. Your speedo will read almost 4MPH faster than actual speed at a true 60MPH. The car will lose .75" of ground clearance, and the already huge gap between the top of the tire and the fender opening will increase by another .75"

Looking at the specs on Tire Rack, I didn't see any manufacturer that would recommend that tire for a 9.5" wide wheel. Most use it on a 7.7-9.0" wide wheel. You need to look at a 245/40, 265/35 (8.0-9.5" width) or a 275/35 (9.0-11.0" width) to get the right diameter.

i knew it!
 

thanks guys for your answers, i knew something wasnt right. i think ima go with 275/35/18 for the front and 295/35/in the rear.

thanks
