The Dirt Wizard 27.5+ tyre uses the same aggressive tread the other plus sized Dirt Wizard tyres use with tread block sizes optimised for the specific 27.5+ casing. If you're not familiar, it's a tyre focused - much like a laser - on providing traction and control on the kinds of surfaces where traction and control are nary to be found. While the tread is the same reliable tread we're all used to, the 27.5+ Wizard conjured up a new rubber compound that performs better in every way. It's a compound that yields higher durability and the grip and feel of a much softer tyre. We've also added sidewall protection for yet more durability as well as a tubeless ready, folding bead. The 3" casing inflates to roughly 29" overall diameter which gives some benefits of a larger tyre like ground approach angle and increased footprint, plus some extra cush.Bead Seat Diameter: 584mmRim width: 35mm minimumCasing: 60tpi w/Nylon sidewall protection
