Winter Sottozero 3 Run Flat tires are the third iteration of Pirelli's Sottozero tires designed for high-performance vehicles that encounter challenging winter road conditions. These tires utilize Pirelli's Self-Supporting Run Flat Technology, which allows for temporary extended mobility in case of a puncture and loss of air pressure. They are capable of running flat for up to 50 miles at 50 mph, as specified by the vehicle manufacturer. The philosophy behind the development of the Winter Sottozero 3 Run Flat tires is to provide excellent performance in various winter conditions. They are not only suitable for snowy conditions but also perform well in cool, cold, dry, wet, and wintry conditions. The unique compound used in these tires improves mechanical, thermal, and dynamic properties of the tread rubber, while the directional pattern with enlarged contact patches and specialized shoulders expels water and slush. The high-density 3D sipes enhance braking performance and snow-to-snow traction. The internal structure of these tires consists of twin steel belts and spirally wrapped polyamide for increased thermal stability and reduced sensitivity to temperature changes. Pirelli's manufacturing process ensures consistent application of additional sidewall reinforcements, which enable the self-supporting run-flat capability. The Winter Sottozero 3 Run Flat tires meet the industry's severe snow service requirements and are marked with the three-peak mountain snowflake (3PMSF) symbol. It is recommended to install Pirelli Winter Sottozero 3 Run Flat tires in sets of four to fully utilize their traction capabilities and optimize handling characteristics. While not classified as run-flat tires, tires with the MOExtended or MOE label on their sidewalls offer similar characteristics by providing limited temporary extended mobility after a puncture. However, they should not be used as a substitute for conventional run-flat tires when necessary. To determine the appropriate tire type for your vehicle, consult the Original Equipment tire listing or refer to your vehicle owner's manual.
