WTB's Weirwolf is a Mark Weir's signature tread. It's a high-volume, fast-rolling tire that climbs like an angel and corners like a trail-devouring demon. Its terraced side knobs and evenly spaced center knobs grab onto the trail and never let go. Tame that ferocious rock garden, rip through corners, and make every trail your playground with the Weirwolf's oversize casing and do-it-all attitude. And, WTB's TCS tires deliver the ride benefits of tubeless tires with the reduced weight of a non-UST tire, so you get the best of both worlds.
