It’s a tall order to improve the tried-and-true Trail Boss tire, but that’s exactly what we’ve done. The new Trail Boss builds on perfection with a more aggressive tread pattern to match its increased volume. 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 you’re leaning into a corner or grabbing a handful of brake. Most often used as a rear tire, the Trail Boss G2 also provides plentiful traction on hardpack trails when used on the front.

- Considerably increased side knob height to provide unshakable traction even in truly loose, chunky terrain.
- Thick outer knobs eliminate any chance of tire-squirm while cornering.
- Overall knob spacing was increased, meaning we increased the spacing not only outwardly, but also circumferentially.
- Pairs perfectly with the Vigilante 2.5 or 2.6 on the front.

Going tubeless allows you to run lower tire pressures without the added weight of a tube. Lower tire pressure has many benefits, including greater traction, lower rolling resistance over rough surfaces, and decreased risk of a puncture-related flat.

Tubeless-ready rims and tires are parts of a complete system that eliminate the need for tubes by creating an airtight chamber between the rim and tire. Liquid sealant is added to the chamber to fill small punctures and maintain air pressure while you ride.

UST (Universal Standard for Tubeless) is a specific type of tubeless system that dictates the shape of the rim and tire beads. UST rims should be paired with UST-specific tires for best results.
