What is "snow tire"

n. an automobile pneumatic tire with deep tread to give traction in snow

Snow tires—often also called winter tires—are tires designed for use in colder weather, snow and ice. Snow chains can be a slower-speed, temporary alternative in snowy conditions. Snow tires have more sipes than summer tires, increasing traction on snow and ice. Tires designed for winter conditions are optimized to drive at temperatures below .

Studded tires with metal pins that protrude from the tire can greatly reduce skidding and accidents on snow or ice-covered roads. However, the metal studs make contact with the road pavement and eventually cut into the pavement, allowing water to get in. The water can cause road damage and create hydroplaning hazard.
