The typical studded tire is a winter tire with small metal studs (many winter tires can come studded or studless). These studs are usually made of tungsten carbide (an extremely hard metal) and have
The total number of studs as well as their arrangement varies greatly among winter tires. If the tire is designed right, the studs will be arranged in a pattern so that they hit in 4 for more different spots of contact with the road. This ensures that every stud has a fresh spot on the ground for maximum traction. Some tires have as little as 2 contact points, some as many as 5.
In the Vermont and Northeast environment, studs give improved ice and snow braking as well as improved lateral stability. Also, because of the mechanical connection to the road, studded tires lose traction in a more gradual and predictable way then their studless counterparts. They never totally lose traction no matter what surface you are on or how cold it is. This all adds to a safer more predictable driving experience.
Studs also have a break in period in which the stud “sets”. During this period drive more gingerly and try to avoid spinning on start of sliding to a stop. When the nubs have worn off on the tread of the tire is a good indicator that the studs are set.
