The Surly Dirt Wizard tire is tall and wide to bring cushion, traction and control to the kinds of surface where neither traction nor control are to be found—and cushion is always appreciated.


  • Dual-row center tread is composed of aggressive beveled knobs; well-spaced siped knobs dig into loose corners
  • Casing is flexible and responsive, yet durable and supportive
  • Features tread and sidewall flat protection
  • Minimum outer rim width is 35 mm
  • Surly recommends checking with your rim manufacturer to verify rim and tire compatibility before assembly or use
  • Note: Tire images shown may not reflect size/color/material options available on this page
