Surly Dirt Wizard 29+ Tire

Called 29+ 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 29 x 3.0-inch size. There's also a choice between a 60 or 120 threads-per-inch casing, so you can decide whether you're interested in supple or very supple tires. Intended for rims 50mm wide, its aggressive knobbies deliver excellent traction and control in corners and through loose, mixed terrain.
