All-season tires are designed to function well in a wide range of temperatures and conditions. Still, when it starts to get cold outside, the stiff rubber that makes for a smooth and quiet ride under normal conditions, can get cold and lose traction and performance. The softer rubber that winter tires are made of will stay supple and continue to grip the road in snow and ice throughout winter.
Winter tires are also made with a deeper and more aggressive tread that sheds water and snow more easily. Replacing your winter tires with all-season ones is important in the spring because winter tires will wear more quickly when driven on hot pavement.
