i have 22's on mine with 265.35.22, and am planning to go with 305.45.22's. With those i think that there will be slight rubbing on hard turns. But i have seen a friend of mine with 24's but he can hardly turn, and theres not much tire at all. so basically if you want rims you either want 20's or 22's but i know for a fact that with those 305's that will be the largest you want to go.
