With a more aggressive tread pattern to match its increased width, the WTB Trail Boss tire is most often used as a rear tire—yet it provides plentiful traction as a front tire on hard-packed trails.

  • Features

    • Rear-focused design with toothy knobs maximizes braking traction while tighter spacing improves longevity by increasing the total surface area counteracting heavy braking
    • Generous spacing between sizable knobs provides better traction in loose or wet conditions while staying true to its fleet-footed heritage
    • Tightly grouped center knobs cut down on rolling resistance without hesitating to dig in while braking
    • Large, supportive side knobs dig deep whether you're leaning into a corner or grabbing a handful of brake
    • Tall outer knobs quickly provide traction in the earliest phases of cornering
    • Directional siping on the center and intermediate knobs improves traction whether accelerating or braking by increasing the amount of working edges that bite into the trail
    • Siping on the outer knobs runs parallel to the tire to provide the surface of the knobs with more cornering traction
    • Standardized Tubeless Compatible System (TCS) nearly eliminates flats and allows lower tire pressures to improve traction and comfort over a traditional tubular tire
    • TCS Light tubeless casing features 1 layer of casing to minimize rotational weight while increasing the overall liveliness of the tire
    • SG2 puncture protection technology provides bead-to-bead coverage to ensure both the tread and sidewall are protected from slashes and punctures
    • TriTec technology blends 3 rubber compounds for different levels of traction, support and durability based on placement in the tread
    • Pairs well with the WTB Vigilante 2.5 or 2.6 in. tire on the front (not included)
    • Ideal for dirt, loose over hard, and hard-packed terrain
