I have had 3 sets of mickey thompson baja mtzs on a expedition. 40-60k miles on each set with mainly highway use, and some beating on it off road. Yes im that awesome. Did great in sand in the desert, did well with mud here, and was a great quiet tire for road use. Little more expensive then the ones above but worth the money IMO
There is a mickey thompson Baja STZ tire thats a little less offroad then the mtz that still looks to be a good tire.
