Can I put 235/40 on the 17X7.0 rims? Like the rims but the tires are too thin. Thanks
Ummm he maybe right, but we're going up in size not down right? So it should affect it as much. But also I just remembered that my rims have a special lip that locks the bead of the tire so the previous information may only apply to Mcoupe/Mroadsters.Originally posted by OPENWIDE:
NO,NO,NO!. Go to any of the tire manufacturers web pages and look up the size tires you want; there will be a table listing the recommended wheel width for each tire size. Don't go beyond (smaller) than the minimun width or else
1. You'll void the tire warrantee
2. The tire may come off the rim during a sharp turn and you can get hurt.
To use a 40 aspect ratio you will need to go to an 8" wide wheel.
Believe me, I do open track racing in my 97 Cobra.
Can't wait to mod my white IS.
Best, Steve

Typically, a tire canbe mounted on a wheel NO more than 2 inches narrower, i.e. upto a 225/ 40 or a 225/ 45 tire for a 17x7 wheel. Nevertheless, the "225" designation of the tire is measured at the bulging part and NOT directly related to the width of the contact patch to the ground, which is mainly determined by the width of the wheel instead. A "225" (8.8 in) tire would give essentially the same contact patch as a "215" (8.4 in) tire on a 17x7 wheel, but the "225" tire is heavier and it may look better. Either way, a 235/ 40 tire would need at least a 17x7.5 wheel.Originally posted by dreamwonder:
