The Winter Sottozero Serie II is Pirelli's second generation of Sottozero Performance Winter / Snow tires developed for the drivers of premium, high performance vehicles facing challenging wintertime road conditions. The Winter Sottozero Serie II was developed with the philosophy that winter / snow tires must perform in a variety of unpredictable weather conditions and aren't just for use in the snowbelt states. Winter Sottozero Serie II tires are designed not just as winter / snow tires, but as seasonal tires suitable for the weather and road conditions typically experienced in parts of the U.S. between November and April by providing traction and handling in cold, dry, wet and wintry conditions
