iz vikipēdijas:

"Winter tires are designed to remain pliable in subzero temperatures. They often have fine grooves and siping in the tread patterns that are designed to bite into the ice and snow on the road. Winter tires are usually removed for storage in the spring, because the rubber compound becomes too soft in warm weather resulting in a reduced tire life.
Many winter tires are designed to be studded for additional traction on icy roads."

Varētu būt "studded winter tire" vai arī "studded snow tire".
