The outside part of the stud is a cylindrical metal jacket or body that is held in the tire tread rubber by a flange at the base. Tires already driven on cannot be studded nor re-studded.

How fast can you go with studded tires?

Because it takes some time for the lubricant to evaporate and the tread rubber to compress around the stud, studded tires require a special break-in period.

How are studded tires made?

These studs are usually made of tungsten carbide (an extremely hard metal), weigh 1.7 – 1.9 grams each and protrude about 1.2 – 1.5 mm from the tire surface. Studs are made by embedding a small metal “jacket” into the tire then inserting a tungsten carbide pin into the jacket (see Figure 2).
