I know for a fact I can safely run a 275 on a 9" wheel, but I think that's about as much as it'll handle. Rim selection within my budget has been a bit of a deciding factor. I know my car will accept a 10.5 rim in the back and 315's with a 5.5 backspacing. I've had trouble finding rims that I like (tasteful, not ghetto king, drug dealer stuff) that are available in both 9" and 10.5" widths in a 17" diameter with the right bolt circle, back spacing, etc. Oh well, if I run 275's all around I can rotate them and extend tread life and my engine's not so hardcore as to require anything bigger than a 275 out back. Thanks guys.

Are the 275's you plan on running using the 40 aspect ratio? Has your suspension been lowered at all?
