What is the difference between winter tires and summer tires?
The winter tire is designed to deliver its best performance at temperatures below + 7 ° C. It differs from the summer tire with the flexibility of its rubber and the density of the notches of its profile. The properties of the rubber constituting the tire tread depend primarily on the air temperature. The summer tire is optimized for driving at temperatures above + 7 ° C. Below this threshold, the tread rubber hardens and its performance gets worse. In winter tires, the elasticity of rubber is shifted towards lower temperatures. This ensures better grip when driving in winter conditions.
