As the original urban assault tire, Maxxis 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. The Hookworm is available in an array of sizes for a variety of applications.

The most important part of a tire is arguably the rubber compound used within the tread and with Maxxis's Single Compound you get one compound throughout the tread for longevity and performance. 


  • Extreme durability for urban assault, park riding, commuting, etc. 
  • Grooved slick tread design
  • Wrap around tread pattern for great cornering grip on pavement

Maxxis Hookworm Urban Assault Tire (Black) (20") (1.95") (406 ISO)
I absolutely love these Maxxis tires. I put 29 miles on them the day I got them and had the best ride ever and I didn’t get a flat. I’ll definitely buy these again, I love the 1.75 size and the 85-110 PSI rating. These tires ride very nice, I will definitely buy them again.
