I just bought a 1999 Chevy Blazer 4X4 and was wanting to know the biggest tire that will fit without too much or no rubbing. I was considering putting a 2" body lift on it but would rather just stick some 31" tires on without a lift. Will they fit or will I have to settle with the 30" tires with no lift?

Hi there, I don't know about the 31" but I was wondering if a stock Blazer S10 1999 can take 30"?????

Thank you.

4x4 S-10 Blazers will fit a 30x9.5x15 tire with no modifications. To fit a 31, you will need to trim or install a body lift. I have 30" tires on Blazer and they have never rubbed nor have I done any trimming.
