Dirt Wizard – First Contact

surly 29x3 dirt wizard tire rolled tread

Our pair of test Dirt Wizards arrived at the Fat-Bike.com – Colonel Steve Austin Memorial Test Bunker and Proving Grounds late this afternoon and all plans for launching the fat-bike.com mobile command center got put on hold…..because this is the tire that we’ve all been waiting for! You know the first thing that we do, when we receive a new pair of sneakers, is throw them onto our Park Tool Digital Scale. Our pair of DW’s weighed in at 1007 and 1000 grams.

The dirt Wizard is slightly smaller that the Knard 29 x 3. When laid flat, the bead to bead width measured 170 mm and the outer tread to tread was 80 mm. I mounted the DW to our set of Surly Rabbit Hole rims and right after mounting the Dirt Wizards measure 73 mm wide at the outer most tread shoulder and the casing inflated to 69 mm at it’s widest point at 32 psi.

The knobs are 3mm tall in the center and a healthy 5 mm tall at the shoulder of the tread. The sidewall reads – “Two wrongs don’t make a right, but three lefts do” (circular logic). I threw them on my Krampus, Silver, and I’ll be taking them on a tour for the next ten days, to give them some trail time. These tires look like they can handle just about anything, so stay tuned for our live action report coming up soon!

    I love bike tire proverbs! Dirt Wizards are looking like one of the best 29+ tires, hands down. Nothing else is as pure dirt tire, period! Now where is the 26×3.0 version?

      It’s already out there, but I believe the sidewall is not as burly.

    How wide is the Knard on those rims? I’m hoping for a tire that is just a hair smaller than the Knards or the Chupacabra, so I can fit them in the carbon rigid fork I already have. The Chupacabras fit, but the natural variation in the freshly mounted tire made some of the side knobs rub the fork.

      The width of the Knard is 80mm

    We just built up some 29″ DW’s on Scraper rims for our tandem, first time out we ran them hard on a steep flow trail. The DW’s are a much better ride than the Vee Rubber Trax Fatty 3.25, the volume is more appopriate for all around riding, they have very little bounce, and the traction is excellent on dry surfaces.

    Suprisingly, at 20psi they felt stiffer than the Trax Fatty at 20psi, which is deceiving when you compare the lighterweight DW sidewall to the much burlier and “thick” sidewall of the Trax Fatty.
