Concave Aluminum Carbide Studs
The 45N 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 increased traction. Any wear that occurs to the carbide crown creates an even sharper edge.
The Studless version TR4528 can accept 45Nrth studs using the Stud Insertion Tool.
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.
