Replacement Studs in galvanized steel base

Hard wearing carbide stud clad in a galvanized steel base.
This stud is used in our Marathon Winter, Snow Stud and Ice
Spiker tires.

In order to ensure that spikes are permanently fixed, tires
should be run in for about 40km on asphalt, while avoiding
any fast acceleration or heavy braking.
