Pretty much anything in a 31x10.5x16 (265r/75/16)will work. If you crank the front t-bars just a bit (take out the downward rake of the front end) the trimming will be kept to a very minimum. The BFG TA's, Mud Terrains and most others will be easy to find in that size. Plus if you ever decide to lift they still look good!
