The Trail Boss SG1 builds on perfection with an aggressive tread pattern to match its width. Generous spacing between sizable knobs provides better traction in loose or wet conditions while staying true to its fleet-footed heritage. Large supportive side knobs dig deeeeeeep whether youre leaning into a corner or grabbing a handful of brake. Most often used as a rear tire the Trail Boss 2.4 also provides plentiful traction as a front tire on hardpack trails.SG1 puncture protection runs under the tread cap and has extended bead protection.
Designed to be the middle-ground trail tire featuring tight groupings of center knobs that reduce rolling resistance without hesitating to dig in while braking. Tall outer knobs quickly provide traction in the earliest phases of cornering
Center and intermediate knobs are siped in a direction that improves accelerating and braking traction by increasing the amount of working edges that bite into the trail when you crank on the pedals or slam on the brakes. Outer knobs feature sipes that run parallel to the tire to provide the surface of the knobs with more cornering traction
Rear-focused design with toothy knobs to maximize braking traction while their relatively tight spacing improves improve braking forces. Substantial side knobs overhang the sidewall of the tire to protect it from slashes while you’re steering with the rear. WTB suggests pairing the Trail Boss 2.4 with a Vigilante 2.5/2.6 on the front
TCS (Tubeless Compatible System) is WTB’s standardized tubeless system which nearly eliminates flats and allows lower tire pressures to improve traction and comfort over a traditional tube-type tire
SG1 puncture protection runs beneath the entire tread cap making the tire more resilient against sharp objects lurking in the dirt combined with Inner Peace + technology tripling the height of its apex bead protection for SG1. This enhancement not only shields the tire bead from damage but also significantly bolsters the sidewall structure
An updated High Grip compound not only increases tread longevity but also improves grip at the same time especially in wet conditions
TriTec blends three distinct rubber compounds to provide different levels of traction support and durability based on their placement within the tread. High durometer rubber provides a foundation for the entire tread pattern and even extends slightly into the base of each knob to provide additional support below the softer compounds used in the remainder of each knob. Center knobs feature a medium durometer compound to provide traction and durability without sacrificing rolling efficiency while outer knobs feature the softest compound for maximum grip and slow rebound characteristics
TCS Tough Casing features two full layers of casing span bead-to-bead to ensure every surface of the tire is more resistance to punctures provides additional sidewall support while cornering and increased traction by running lower pressures than would be possible with thinner single-ply casings. TCS Tough tires are the sure bet for aggressive trail enduro gravity and e-bike riders who want ultimate peace of mind out on the trail
