Pirelli Winter 240 Sottozero RFT Tire Reviews

Product Details

Winter 240 Sottozero RFT tires are Pirelli's "dual-season" Performance Winter / Snow run-flat tires 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 240 Sottozero RFT tires feature Pirelli 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 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 240 Sottozero RFT tires are designed to be effective as temperatures approach freezing and below from mid-autumn until early spring by offering hot performance compared to summer tires when driven on dry, wet or icy cold surfaces.

The Winter 240 Sottozero RFT tread compound utilizes cap and base 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 inner and outer elements to blend traction in snow and on ice with drivability on dry and wet roads. The tire's internal structure includes 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.
