Be a Boss on The Trails

Be the boss of the trail with WTB's Trail Boss 27.5" TCS Mountain Bike Tire. This Tough/Fast Rolling tire provides the ride you've always wanted, crushing the corners while powering through poor conditions. A TriTec compound construction allows for unbelievable durability, allowing you to embrace your next adventure.

It's a tall order to improve the tried-and-true Trail Boss tire, but that's exactly what they'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 deep — 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.

This TCS Tubeless tire makes for a ride you won't soon forget. Weighing in at an ultra-tough 1156 grams, the 27.5" by 2.4" WTB Trail Boss TCS MTB Tire is just what you need for the ultimate bike upgrade. Designed for trail or enduro riding, the Trail Boss is perfect for loose over hard, dirt, loose, or rocky conditions.


  • 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 outward, but also circumferentially
  • Pairs perfectly with a Vigilante 2.5 or 2.6 on the front
