Byway is for days of endless hardpack exploration and gravel grinding while also providing noticeable efficiency on any pavement linking it all together. A swiftly smooth centerline is paired to a textured intermediate section that provides a seamless transition onto small outer knobs for unwavering traction in loose dirt and gravel. Prominent outer knobs also extend down the sidewall to provide an additional level of defense from roadside unpleasantries of all shapes and sizes. Byway 34 is an identical replacement to the previously named Exposure 34 tire. We renamed the tire to create a uniform naming structure where all tires are named according to the tread pattern. SG2 PUNCTURE PROTECTION: Most sizes of this tire are available with our all-new SG2 Puncture Protection, which is a lightweight nylon insert that provides bead-to-bead coverage and ensures every area of the tire is defended against slashes and punctures. As events become progressively rougher and cyclists pedal farther, gravel gets tougher. It only makes sense for gravel tires to become tougher as well. Please refer to the charts below to determine which versions are available with SG2. - Nylon fibers have a flat profile, which reduces the amount of rubber needed to fill the gaps between fibers and minimizes weight. - Protected SG2 gravel tires feature a 120tpi casing, which improves suppleness compared to a traditional 60tpi tire. - SG2 was specifically designed to be a puncture protection layer, but it also improves air retention and eliminates seeping at the sidewall. FEATURES: - Smooth centerline for efficiency with diamond-shaped outer knobs for grip in the dirt. - High volume tire enables a comfortable ride. - Dual Compound rubber means a fast-rolling tire with great corning traction.

Aggressive, premier and unwavering...those were words we used to describe the highly esteemed Vigilante 2.3, and they still ring true for these wider brethren. We simply dreamt of ripping trails on wider versions of our favorite aggressive mountain tire. We wouldn't hand you spineless claims about vast improvements unless they were true. The new Vigilante has received a substantial increase in both the height and surface area of the side knobs. Tall, stout outer knobs not only dig deeper, but also start digging sooner in the initial stages of cornering. Wider, taller, and more aggressive in every way: the new Vigilante. TriTec And Slash Guard: All Vigilante tires feature TriTec Compound, which utilizes three rubber compounds to provide different levels of traction, support, and durability based on their placement within the tread. The entire tread pattern is supported by a base of high-durometer rubber, which also transitions halfway into the height of the knobs and allows for the use of softer knob compounds without the tire folding under cornering forces. The top of the center knobs consist of a medium-durometer compound to provide traction and durability without sacrificing rolling efficiency, while the outer knobs feature the softest compound to deliver maximum grip and slow rebound. All TCS Light versions of the new WTB tires feature Slash Guard technology, which incorporates a protective nylon insert spanning the entire sidewall to provide extra protection without the weight of a dual-ply TCS Tough casing. - Square-lugged knobs deliver unwavering traction, yet benefit from added height to ensure they dig even deeper into loose, unpredictable terrain. - Updated siping arrangement places emphasis on cornering forces, while the larger knobs don't discriminate against shamelessly forceful cornering or reckless braking. - Increased circumferential spacing allows the tread to remain clear in sloppy conditions, while still keeping the casing protected from spiteful rocks. - Vigilante is optimized for use with i29 rims.
