An aggressive tread focused on traction and control in loose and varied terrain, with beveled leading edge dual row knobs in the center and well-spaced, siped edge knobs to dig into loose corners.
Designed to be run on 50mm rims, the 2.75" casing inflates to about 27.5" overall diameter (that's pert near 650b, folks), meaning you get some benefits of a larger diameter tire like ground approach angle and more footprint, with easier maneuverability of a smaller diameter tire, plus some extra pneumatic cushioning.
Minimum rim size for these bad boys is 35mm.

asked by: a guest What is the minimum tire pressure recommended.
anwered by: canteau There are a lot of factors when determining minimum tire pressure such as rim width, rider weight, terrain, tube type or no tubes at all.... Generally you're probably going to find that the Surly Dirt Wizard Tire works best somewhere between 12-20psi.
