I just had 275-40-17s mounted on an 8.5 inch rim that I thought was larger, mistaken reading earlier in life... Well my question is that on Tirerack.com it says that this tire has a rim width range from 9"-11", Since I am .5 inches too small what will the Ill affects be? Is my tire going to pop off the rim at high speeds? Please, I need help before I roll to Seven stock with this setup...
Thanks In Advance,

the tire or wheel width is half an inch too short... i'm not an expert, but i don't think that it would matter either way, that's only a quarter inch on each side (yeah, i can multiply too!!!)

anyways i'm sure rishie (ard t2) or sleepR1 will have a better answer

 

It will be fine. You're not making the best use of all 275-mm but...you will not pop the tire off of the rim...

 

the tire may not wear evenly ,try to keep the wear even by raise or lower the air presure as you see wear patterns start.

 

Okay, thanks alot guys, this eases my head... I think I would be stressing the whole way to SS5 without you guys.
Much Thanks!
