Designed by WTB Pro cross country and downhill racer Mark Weir, the WeirWolf features a fast-rolling, soil-piercing center tread for low-rolling resistance. Now this is where the fun starts. An extra row of transitional tread between the crown and side knobs gives the WeirWolf a positive feel and consistent traction at any lean angle, from moderate to extreme. And at those extreme angles, the progressive stiffness of the outer knobs lets you carve like never before! Weir will tell you that many races are won or lost in the corners, so win by using WeirWolf tires.
