The Winter Sottozero Run Flat is Pirelli's "dual-season" Performance Winter / Snow run-flat tire developed for the drivers of high performance sport cars, coupes and sedans who don't let their enthusiasm for driving cool off in winter. Winter Sottozero Run Flat tires feature Pirelli’s Self-Supporting Run Flat Technology that enhances safety and convenience by providing temporary extended mobility in the event a puncture allows complete loss of air pressure. Pirelli’s Self-Supporting Run Flat Technology allows tires to literally "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. Winter Sottozero Run Flat tires are designed to be effective as ambient temperatures approach freezing and below from mid-autumn until early spring by offering hot performance compared to summer tires when driven on cold, dry, wet, snow-covered or icy surfaces.
Winter Sottozero Run Flat winter / snow tires utilize a cap and base tread compound technology that combines two different compounds. The upper strata (cap) that comes into contact with the road surface uses Pirelli's latest generation silanes to bind the silica and polymer to provide greater stability during hard driving in both wet and dry conditions. The sub-strata in contact with the casing (base) uses nano-composites (aluminum silicates) dispersed throughout the polymer to provide the stiffness that enhances stability and driving precision. The tread compound is molded into an asymmetric tread pattern divided into distinct outboard and inboard elements to blend drivability on dry and wet roads with traction in wintry conditions. High-density siping provides more biting edges to increase snow traction. The tire’s internal structure features Pirelli’s ultra high performance tire constructions to offer levels of performance not normally associated with winter / snow tires.
Pirelli's extended mobility solution is made possible by their MIRS computer-controlled robotized manufacturing system, a production process that assures consistency in the application of the additional sidewall reinforcements that provide the self-supporting run-flat capability.
Winter Sottozero Run Flat winter / snow tires meet the industry's severe snow service requirements and are branded with the mountain/snowflake symbol.
Install Pirelli Winter Sottozero Run Flat tires in sets of four only.
Due to the traction capabilities of the Winter Sottozero Run Flat tires, Pirelli recommends using them only in sets of four to provide the best handling characteristics and tire performance.
