If you use special studded tires to drive on ice or snow, what is the maximum distance the studs are allowed to protrude?

Question

DentroTest · Accepted Answer

Spanish regulations state that studded tires, permitted only when there are layers of snow or ice on the road, must meet specific characteristics to avoid damaging the pavement. The studs must have rounded edges and cannot protrude more than 2 millimeters from the tire's surface. Therefore, any measurement exceeding this (such as 3 mm or 4 mm) is prohibited as it would cause excessive deterioration to the public road.
