Winter tire studs are designed to be installed on studdable winter tires, and work to supplement traction in select winter conditions. Studdable winter tires are sold without studs. They must be acquired and installed separately.

Winter tire studs have a large diameter cylindrical end that roots down into the tire tread, and a small tungsten carbide pin that extends from the “active” end of the stud. Hard rubber studs are also available.
 

Once installed, the top pin of the stud extends beyond the surface of the tire tread by about 1/32", and works to penetrate frozen roadways to provide extra grip. Think of studs as hammering and clawing into frozen precipitation under wheel rotation.
