The inner tread area sports additional siping detail to boost the winter weather road gripping ability, especially in snow and on ice. The outer tread area's tread grooves increase the water evacuating ability and with it the tire's resistance to hydroplaning. The winter weather road gripping ability is further enhanced with the Temperature Dynamic Compound that improves the winter weather traction and makes the rubber flexible even in colder winter temperatures. The winter weather safety is ensured this way.
