I have a 79 Malibu. I have had 15" Corvette Rally wheels on it since I bought it six years ago. I am wondering if anybody knows what the biggest size of 15" tire I can go to is without rubbing in the front. Right now I have 205/75/15's.

225/60 r15's would probably fit.
A decent tire shop would probably allow you to fit one on a rim and test-fit before buying them.

Thanks for the help.
