The Baja Pro X (SxS) from Mickey Thompson is a competition-proven extreme-terrain tire that's designed for mud bogging, rock crawling, and other rough off-road applications. The Baja Pro X (SxS) is designed with a damage-resistant extra-sticky tread formulation for traction on hard, irregular surfaces, and utilizes Mickey Thompson's Pro-Tech construction package for extra durability. Its innovative extreme-terrain tread features serrated tread elements, a symmetric directional tread with a high void ratio for good self-cleaning, and a system of mud scoops, massive SideBiters, and angled shoulder scallops for excellent grip, with dual decoupling grooves for flexibility while doing aired-down rock crawling. NOTE: the Baja Pro X (SxS) is not DOT-approved for highway use.
