WTB was founded by and is controlled by people who care about riding mountain bikes.  Tire passion runs deep and is a matter that is beyond personal to us, we’re downright particular about our treads.  From our Ground Control tire designed for Specialized in 1985 to our 2013 Nine Line tire co-developed with Cannondale and input from our global race team, there’re a lot of tires in between.

WTB is responsible for the first 29” tire, the NanoRaptor 2.1 in 1999 and this tire is symbolic of the independence, ingenuity, and unadulterated creativity that go into each of our tread patterns today. 29” bicycles were the shameful dunces of a time period where wheel size could not be questioned.  The overwhelming popularity of this wheel size today in the global marketplace only gives credence to WTB’s unflinching spirit of innovation.

WTB’s tire future heads fearlessly forward with aid of 3d modeling, industrial design standards, and direct feedback from racers and customers.  Our wholehearted approach to Enduro racing has resulted in square-edged, open-tread patterns proven in the Alps and Dolomites.  New casings retaining compliance yet yielding impervious protection have resulted in a new understanding of what tires are capable of.  Tuned rebound characteristics and optimized durometer compounds are resulting in tires that allow our athletes and riders to push the sport further.




Our proprietary 60 durometer rubber compound offers the ideal mix of rolling efficiency and traction for XC and trail riding applications. DNA rubber is renowned for being versatile and long lasting.


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.


45a durometer, glue-like conforming rubber covers a supportive 60 durometer base creating uncanny traction with tuned rebound characteristics designed to take harsh hits yet not fumble for footing.


Found in WTB and Freedom’s pavement tires, this compound is specifically formulated to maximize the lifespan of tires. Sick of wearing out tires yet don’t care to ride on a pair of Crayons? Try our Distance Compound for a harmonious pairing of longevity and traction.


Tubeless Compatible System: Standards-driven system designed around tubeless bead shapes and hooks to create repeated sealant-based consistency between tire and rim.


A robust and substantial casing provides the strength needed for our wire bead tires to last. A high ratio of rubber to thread protects against trail threats and urban unpleasantries. Found in all Comp level tires.


A supple, gram-conscious carcass designed to be compliant and conform to trail objects while still providing a happy balance of low rotational weight and rugged reliability.


Take our proven Lightweight Casing found in TCS Light tires and… well… double it. Yep, Enduro Casing is composed of two full layers of casing, leaving no area unprotected on our TCS Tough tires. Developed through real world testing during the Enduro World Series, this casing is designed to take punishment and has been optimized for sealant usage, retention, and consistency.


Folding beads are lighter than conventional steel beads and easier to install. Steel beads are more economical and better suited for aggressive, trail riding applications.


Sipes are small incisions on a tire’s tread. Siping a knob creates more working edges, which boosts traction in virtually any condition. Because WTB’s high-end mountain bike tires feature shallow sipes, the knobs stay firm under heavy loads and hard braking.


WTB recommends that tire pressure be checked before each ride. The acceptable pressure range for tubed mountain bike tires is 35- to 65-psi (2.4- to 4.5-bar). Road tires must be inflated to 100 to 130-psi (7- to 9-bar). TCS tires must be inflated between 30 and 50 psi (2- to 3.5-bar). City/Trekking/Hybrid tires must be inflated between 50- and 80-psi (3.5- to 5.5-bar). Tire pressure outside of these guidelines can result in a loss of control or, at the very least, poor performance.


TPI stands for threads per inch. This number refers to the thread count in a tire’s casing. A lower TPI indicates that thicker threads are woven into the casing, therefore making it more durable; a higher TPI indicates that thinner threads are used, therefore making the casing lighter and more pliable. WTB’s 60 TPI Race and TCS tires offer supple, shock absorption qualities while remaining resistant to cuts and tears.
