OK, I had a sidewall give out yesterday, so Wifey is giving me permission to get new tires.....I have a 91, so I am stuck with the 15" rims, and cant afford to upgrade to a larger wheel at this point. No lift at this point, but hopefully there is somewhere in my future.....I have searched, but cannot find the largest tire that I can get on this rim. Can I still put at least 33's on it? That is what I am trying to find now, but cannot see this size anywhere...Help.
