Winter Sottozero 3 Run Flat tires are Pirelli's third generation of these Performance Winter/Snow run-flat tires developed for the drivers of premium, high performance vehicles facing challenging wintertime road conditions. They feature Pirelli's Self-Supporting Run Flat Technology that enhances safety and convenience by providing temporary extended mobility in the event a puncture causes complete loss of air pressure, allowing to "run flat" for up to 50 miles at 50 mph (80 km at 80 km/h) unless otherwise specified by the vehicle manufacturer for Original Equipment tires.
Designed to provide traction and handling in cool, cold, dry, wet and wintry conditions, Winter Sottozero 3 Run Flat tires are designed not just as snow tires, but as seasonal tires suitable for the cold weather and freezing road conditions. These tires use an innovative compound with specialized polymers that improve the tread rubber compound's mechanical, thermal and dynamic properties. The compound is molded into a directional pattern that features an enlarged contact patch comprised of arrow-shaped center blocks and more rounded shoulders to expel water and slush. High-density 3D sipe technology improves braking performance and snow-to-snow traction.
