Trail Boss calls the shots out on the trail. A true all-around-er, this tire feels at home on your local singletrack. With an aggressive tread pattern, Trail Boss rolls faster than you’d expect. 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 also provides plentiful traction as a front tire on hardpack trails.

Usage: Cross-Country • Trail • Enduro
Conditions: Loose Over Hard • Dirt • Loose • Rocky


1. No-Compromise Tread: Some tires are semi-slick and fast while others are chunky and bite. Trail Boss is designed to be the middle-ground trail tire. Tight groupings of center knobs cut down on rolling resistance without hesitating to dig in while braking. Tall outer knobs quickly provide traction in the earliest phases of cornering.
2. Strategically Directional Siping: Center and intermediate knobs are siped in a direction that improves accelerating and braking traction by increasing the number 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 in order to provide the surface of the knobs with more cornering traction.
3. Rear-Focused Design: Trail Boss 2.25 features toothy knobs that maximize braking traction while their relatively tight spacing improves to improve the longevity of the rear tire by increasing the total surface area and counteracting heavy braking forces. Substantial side knobs overhang the sidewall of the tire to protect it from slashes while you're steering with the rear. We suggest pairing the Trail Boss 2.25 with a Vigilante 2.3 on the front.
4. Tubeless Compatible: Most Trail Boss 2.25 tires feature a TCS tubeless casing. TCS (Tubeless Compatible System) is WTB's standardized tubeless system. These tires feature a TCS tubeless casing, which nearly eliminates flats and allows lower tire pressures to improve traction and comfort over a traditional tube-type tire.

*WTB's tire pressure recommendations have changed over time due to further developments in technology. Riders may always reference the markings on their tires for allowed pressure ranges, but may also consult wtb.com for the most up-to-date tire pressure recommendations from WTB. We calculate pressure recommendations based on average rider weight of 160-180 lbs and suggest increasing our minimum recommended pressure on WTB.com by 2-3psi for every additional 10 lbs of rider weight. Never exceed the maximum tire pressure marked on a tire.

  • TCS: TCS (Tubeless Compatible System) is our industry-leading tubeless rim/tire system designed to international ETRTO and ISO standards.
  • Light Casing: One layer of supple, gram-conscious casing conforms to the terrain to provide maximum performance, exceptional reliability and low rotational weight.
  • Fast Rolling Compound: Specifically formulated to prioritize rolling efficiency while also providing dependable traction and lasting durability. 
  • Tritec Compound: Three compounds provide optimal levels of traction, support and durability. Different durometers of base rubber, center knobs and soft knobs allow us to fine-tune performance and increase rider confidence.
  • SG2 Protection: Available with SG2, which defends all surfaces of a tire by providing an uninterrupted layer of nylon puncture protection spanning from one bead to the other.
  • Dual DNA Compound: Dual DNA is the perfect mix of efficiency, traction, and durability. The centerline tread features a firmer rubber compound that boasts faster rolling and increased durability, while the side knobs are composed of softer, slower-rebounding rubber that improves control and grip. In other words...speed where you want it and traction where you need it.
  • TCS Light Or TCS Tough?: TCS Light tires feature a single-ply casing whereas TCS Tough tires are dual-ply. XC and trail riders often choose TCS Light tires for their minimal weights while enduro, gravity and e-bike riders prefer TCS Tough for the additional durability and cornering support. Some riders opt for TCS Light on the front where weight is more noticeable and TCS Tough on the rear where a burlier tire is beneficial. Most of our TCS Light mountain tires feature Slash Guard technology, which provides a protective nylon insert spanning the entire sidewall to provide extra puncture protection without the weight of a dual ply casing.
  • SG2 Puncture Protection: TCS Light single-ply mountain tires are available with SG2 puncture protection. SG2 is a lightweight nylon layer that protects all areas of the tire with an additional level of defense against punctures and pinch flats. Bead-to-bead SG2 also improves sidewall stability and overall tire support without the additional weight of a Tough (dual-ply) casing.

Flat nylon fibers within SG2 reduce the amount of rubber needed to fill the gaps between fibers compared to traditional protection layers with round fibers. The increased fiber-to-rubber ratio boosts puncture resistance while reducing weight and improving suppleness compared to our Tough casings. Third-party lab testing showed bead-to-bead SG2 provides 80% more sidewall protection than traditional single-ply tires without SG2.
