Called 26+ by those in the know, Surly's Dirt Wizard tire provides float, cushion, and traction like a fat bike tire, but keeps the handling fast and responsive with its 26 x 2.75 size. Those big dimensions also just happen to be close to a 650b/27.5 inch wheel and mountain bike tire for increased roll over and footprint. Intended for rims 50mm wide, its aggressive knobbies deliver excellent traction and control in corners and through loose, mixed terrain.
