12- to 24-Inch

Tough enough for the meanest streets - Durable enough for urban assault, park riding, commuting, cargo bikes, etc. - Grooved slick tread design - Wrap-around tread pattern As the original urban assault tire, we designed the Hookworm to take the abuses of the most aggressive street riders. Bead-to-bead tread provides durability and traction whether you're dropping staircases, grinding rails, or riding in your local skate park.

Tightly spaced knobs for dirt use - Bidirectional - Engineered for BMX tracks, trail riding, and dirt jumping - Front or rear - Full Square-knob design Staggered, tightly spaced center lugs provide control at speed. The knob spacing increases near the shoulder lugs to produce two channels that hook up on both hardpack berms and loose dirt on the trails.
