The Urban-Assault tire!
This unique smooth urban-assault tire has large air volume for handling bumps in the road. It works great for city riding with its puncture resistant compound and extra volume for curbs and stairs.
The Hookworm features a hard 70a black compound. The high performance qualities of the grooved tread pattern allow straight-line performance and cornering control. The Hookworm is high pressure rated at 110 PSI, which rolls fast and reduces the risk of pinch flats.
For 20″ wheels check out the 20″ Maxxis Hookworm.
