I had the MTZ's in 31x10.5 and didnt like them. They rode loud on the highway, and I didnt like them in the rain either. Additionally I somehow managed to have one deflate on me. I never ran them aggresively offroad. Something managed to puncture the tire all the way through, I'm not sure what. So my final say is don't get the tire. I didnt have a good experience with it, but that's just me. I currently have Dick Cepek Crushers 35x12.5 and I love them so far. I have about 15K on them and I'm just beginning to hear the typical mudder whine on the highway. If you spend most of your time on the road try checking out the Dick Cepek FC II's, they are an aggressive all terrain that wears good and still gets good mud traction, I had a set on my F-250.
