I had Kenda Bearclaws and Maxxis Bighorns on mine. Both worked well. You will need to put wheel spacers on the front if you are going bigger than 8" wide on the front with the OEM wheels. Room enough for anything on the rears with no problem. Bighorns were by far the better tire of the two. Rockers are great as well, but they will cost you some serious $$$!
