Mud Tire Shootout Third Place: Mickey Thompson Baja MTZ

Manufactured in the U.S., the MTZ is Mickey Thompson's flagship mud-terrain. Situated between the more aggressive Baja Claw and its milder all-terrain sister, the ATZ, this tread combines elements of a hardcore mud-terrain and a street-friendly all-terrain. Comprised of four distinctive tread block elements, the pattern features gobs of lug overlap to provide smooth and quiet performance around town. The shoulder lugs feature deep, widely spaced voids to improve mud traction, while long central sipes interrupt every lug for improved performance on wet pavement. The tread compound returned an average Shore A durometer reading of 65, which helps contribute to the MTZ's awesome carcass flexibility and supple ride quality. We fell in love with this tread during our 100-mile test loop. The pattern is very stable in corners, and when asked to stop, it does so with little or no drama. However like most of the tires we tested, the MTZ did experience a cease in forward progress on the rutted S-turn trail at Hollister Hills. A quick back-up and shift to Second gear resulted in ample wheel speed to make the tread clean out and pull us to the top. Construction-wise, the MTZ's tread features one ply of nylon, two of steel and three of polyester. The sidewalls are also comprised of polyester, though one of the three plies is positioned at a slightly different angle from the others to improve high-speed stability within the design.
