45N Gravdal Rouunded Stud Tyre

45N Gravdal Rouunded Stud Tyre

Welcome to the world of high-performance commuter tires. 252 studs are carefully positioned across the 700c x 38mm 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. Available in 120tpi studded, 27tpi studded and 120tpi stud-less versions.

This stud features a carbide tip with a concave shape on the crown.

The concave crown creates a very sharp attack angle to the surface, resulting in an unparalleled amount of traction. Any wear that occurs to the carbide crown creates an even sharper edge – continuously augmenting acceleration, braking and cornering performance as it ages.

Using the same two-piece construction method as the Concave Aluminum Carbide product, the steel-carbide stud features a dome-shaped carbide tip with a steel base, making it a more economical stud for 45North’s 27tpi tire collection, while still providing excellent performance and longevity.

Tiny grooves on large tread lugs create more edges for grip. These grooves also give the tire more flexibility to move over surface undulations, providing enhanced acceleration, braking and cornering traction while also creating a more comfortable ride quality. Siping has been used in the automobile industry for years to augment the performance of tires in winter driving conditions.
