What are studded tyres?

A studded tyre is a type of winter tyre which has extra metal studs inserted into its tread. The exact number of these studs depends on the tyre size and model but it typically ranges from 60 to 120 studs.

The studs give a much greater grip on roads covered with certain types of precipitation such as snow pellets or grains, ice pellets or crystals, graupel, hail etc. Such winter tyre studs provide extra safety in challenging conditions. They are particularly useful on hills and roads covered with crust or slush but also in wet climates with temperatures around 0 degrees where surfaces get wet and freeze.
