For a tire, winter begins at 7 degrees!
At temperatures below 7 degrees, standard tires progressively lose flexibility, leading to a decrease in traction, handling and vehicle control at lower temperatures. However, the rubber of a winter tire remains supple through temperature decreases and has more sipes - the small cuts in the tread block - which cut through surface water and increase grip on cold, damp, slushy, icy and snowy roads. This promotes improved handling, control and safety on the road during fall and winter. In fact, the braking distance of a winter tire compared with a standard tire, depending on speed and road conditions, can be up to two vehicle lengths shorter.
