Gravdal - 26

Studded 26" Commuter Tire

This is a carousel with manually-rotating slides. Use left and right arrow buttons to navigate, or jump to a slide using the slide dots.


216 studs are carefully positioned across the casing profile to yield a level of confidence and safety never before seen in a commuter tire. Siped tread lugs and oval-shaped stud groupings provide exceptional cornering, braking and acceleration traction. Run the Gravdal at minimum pressure for unmatched traction performance, and maximum pressure for a quieter and faster ride on clean roads. Works great with linear-pull and canti-lever brakes.
