Off Road 29 x 2.6" Mountain Bike tyres that are well suited to difficult UK conditions.

The Surly Dirt Wizard is highly focused - one might even say spellbound – on providing traction and control on the kinds of surfaces where neither traction nor control are to be found. Its tread is composed of a dual row of aggressive, trail-gobbling, bevelled knobs in the centre and well-spaced, siped knobs to dig into loose corners.

Designed to work on wider rims, Dirt Wizards are tall and wide, providing next-level traction and cushioning. The casings are flexible and responsive, yet durable and supportive. Minimum rim size for these naughty little wizards is a 35mm outer rim width.

And if those black sidewalls aren't mesmerizing enough, we've made a grey sidewall option you can summon up.
