The Scorpion Ice & Snow Run Flat is Pirelli's Light Truck/SUV Performance Winter / Snow self-supporting run-flat tire developed for the drivers of performance-oriented luxury crossover and sport utility vehicles looking for enhanced wintertime traction. The Scorpion Ice & Snow Run Flat is designed to combine the convenience of temporary extended mobility in the event of complete air pressure loss with enhanced low-temperature wintertime driving capabilities on dry and wet roads, as well as in snow and on ice.Pirelli Run Flat tires enhance safety and convenience by incorporating special sidewall reinforcements that can temporarily support the weight of the vehicle while providing extended mobility even after sustaining air pressure losses that would render conventional tires immobile. Pirelli Run Flat technology will allow tires 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. While internal tire damage after being run flat will make tire replacement necessary, Pirelli Run Flat tires provide drivers the extended mobility necessary to continue through pouring rain, stormy weather and away from dangerous situations. Pirelli Run Flat tires are only recommended for vehicles originally equipped with self-supporting run-flat tires and a tire pressure monitoring system.Scorpion Ice & Snow Run Flat tires feature a tread rubber compound that remains flexible at lower ambient temperatures to enhance grip and handling in typical winter conditions. The tread compound is molded into a subtly asymmetric tread design that features a stable shoulder area to enhance dry road handling, circumferential grooves to provide hydroplaning resistance and help maintain good traction on wet and slush-covered roads while angled independent tread blocks with circumferential and lateral sipes help the tire bite into snow. Sidewalls feature additional reinforcements to provide self-supporting run-flat capabilities. The Scorpion Ice & Snow Run Flat winter radials meet the industry's severe snow service requirements and are branded with the three-peak mountain snowflake (3PMSF) symbol.Install Scorpion Ice & Snow Run Flat tires in sets of four only.Vehicles should always be equipped with equivalent tires at all wheel positions. The Scorpion Ice & Snow Run Flat winter tires, due to their exceptional snow and ice traction provided by their unique tread compounds, must be used in sets of four to help ensure proper vehicle control.
