The square-lugged open tread pattern offers stability in loose or wet terrain, while the stiff outside knobs grip at lean angles like nobodyÆs business. All of WTBÆs new mountain tires feature TriTec Compound, which utilizes three rubber compounds to provide different levels of traction, support and durability based on their placement within the tread. Tough - A double layer of light casing, TCS Tough tires are composed of two full layers of casing, bead-to-bead, leaving no area unprotected on our burliest tires. HG - High Grip, 45a durometer, glue-like conforming rubber over a firmer 60a durometer supportive base for uncanny traction.
