I did 22's w/ 255/35 rubber and the rim was 10" wide with 0 offset and I had to roll the fenders front and back. As long as you have something smaller then a 10" wide rim you should be ok with a standard +13 offset. The 24's I have for it now are actually only 1" bigger then the 22's I mocked it up for. I'm going to be running a 255/30/24 once I get my money back from that dickhead Russell from the Flawless Rim Shop on this site. He boned me big time and didn't send any tire with the rims. Now I'm fighting for my money so I can buy the tires. You can check out my build pics here:
