WTB Trail Boss Comp Mountain Tyre 29x2.25 (Wired)

The WTB Trail Boss Comp Mountain Tyre is a versatile performer that dominates the trails. Designed for all-around trail riding, this tyre excels on local singletrack, offering a perfect balance of speed and traction. Its aggressive tread pattern rolls faster than expected, while the generous spacing between knobs ensures excellent traction in loose or wet conditions. With its large side knobs, the Trail Boss provides exceptional cornering and braking grip. Whether used as a rear or front tyre, the Trail Boss delivers the performance and reliability you need on hardpack trails.

Aggressive Tread for Trail Domination: The Trail Boss Comp Mountain Tyre features an aggressive tread pattern that excels on a variety of trails. It rolls faster than anticipated, allowing you to maintain speed and efficiency. The generous spacing between the sizable knobs ensures superior traction, even in loose or wet conditions. No matter the terrain, the Trail Boss keeps you confident and in control.

Cornering and Braking Confidence: Equipped with large, supportive side knobs, the Trail Boss offers exceptional grip during cornering and braking maneuvers. Lean into corners with confidence as the side knobs dig deep into the trail, providing maximum traction and stability. When you need to slow down, grab a handful of brake with the assurance that the Trail Boss will keep you in control.

Versatile Performance: The Trail Boss is primarily used as a rear tyre, where its tread pattern and knob spacing deliver excellent traction and speed. However, it also performs admirably as a front tyre on hardpack trails, providing ample grip and control. Its versatility makes it a reliable choice for various trail conditions and riding styles.

Features of WTB Trail Boss Comp Mountain Tyre 29x2.25 (Wired)

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.

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.

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.

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.

Technologies of WTB Trail Boss Comp Mountain Tyre 29x2.25 (Wired)

TCS: TCS (Tubeless Compatible System) is our industry-leading tubeless rim/tire system designed to international ETRTO and ISO standards.

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.

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.

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.

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.
