I vote for 33x12.50x15s, unless you regear, then get 35s. Also if you mud alot it may be a good idea to get wider rears and skinnier fronts. like 10.50s/12.50s or 12.50s/14.00. It helps cut a patch. My TSLs up front cut through and direct me while my fat rear boggers push and push and push. But you will be dissapointed with that much lift and 32s. Stock CJS will fit skinny 33s in most cases. But with your axle ratio and 6 cylinder anything bigger would bog you down too much.
