Pirelli's Winter Sottozero Serie II Run Flat tires are designed for drivers of high performance vehicles who encounter difficult winter road conditions. These tires incorporate Pirelli's Self-Supporting Run Flat Technology, providing temporary extended mobility in the event of a puncture that leads to complete loss of air pressure. They can run flat for up to 50 miles at 50 mph, as long as the vehicle manufacturer does not specify otherwise. The Winter Sottozero Serie II Run Flat tires are engineered to perform in a wide range of unpredictable weather conditions, not just limited to snowy areas. They are suitable for use between November and April, offering traction and handling in dry, wet, cold, and wintry conditions. These tires feature an ecologically friendly tread compound that eliminates aromatic oils. Pirelli's Temperature Dynamic Compound technology enhances traction on wet and icy surfaces in near-freezing temperatures. With the Interactive Brickwork Siping design in the tread blocks, the Winter Sottozero Serie II Run Flat tires ensure both lateral and longitudinal stability. The sipes create a brickwork pattern, increasing snow traction, ride comfort, and reducing noise. The tires' internal structure includes twin steel belts reinforced by spirally wrapped polyamide, enhancing thermal stability and reducing sensitivity to changes in road and air temperatures. Pirelli's MIRS computer-controlled manufacturing system enables the extended mobility capability of these tires. The manufacturing process ensures consistent application of the additional sidewall reinforcements required for the self-supporting run-flat feature. Meeting the industry's severe snow service requirements, the Winter Sottozero Serie II Run Flat tires are branded with the three-peak mountain snowflake (3PMSF) symbol. It is recommended to install these tires in sets of four to achieve optimum handling characteristics and tire performance. Although not officially labeled as run-flat tires, tires marked with MOExtended or MOE on the sidewalls offer similar characteristics by providing limited temporary extended mobility after a puncture. However, they should not be used as substitutes for conventional run-flat tires when those are required. To determine the appropriate tire for your vehicle, consult the Original Equipment tire listing or refer to the vehicle owner's manual.
