With generous width and an aggressive tread to match, the WTB Trail Boss 29er mountain bike tire boasts plentiful traction in loose or wet conditions, while still offering fleet-footed performance.

  • Features

    • Overall knob spacing is increased—not only outward, but also circumferentially—improving traction in loose or wet conditions
    • Large, supportive side knobs dig deep, whether you're leaning into a corner or grabbing a handful of brake
    • Tall side knob height provides unshakable traction even in truly loose, chunky terrain, while thick outer knobs eliminate tire-squirm while cornering
    • Most often used as a rear tire—pairs perfectly with the Vigilante tire on the front (not included)—this tire also works great up front on hardpack trails
    • TCS (Tubeless Compatible System) Light/Fast Rolling + Slash Guard casing incorporates a nylon insert spanning the entire sidewall for extra protection without excessive weight
    • TriTec Compound uses 3 rubber compounds to provide different levels of traction across the tread
