Pirelli Winter 210 SnowSport Performance Winter tires were developed to combine good snow and ice traction with European high-speed winter driving performance. Available in low profile, high-speed sizes, Pirelli Winter 210 SnowSport tires are for the drivers of high performance sport cars, sport coupes and sport sedans who require winter driving traction on dry, wet and snow-covered roads. Pirelli Winter 210 SnowSport studless winter tires feature an asymmetric tread design with broad, rounded outer shoulder blocks to enhance dry road handling performance. These are combined with independent, intermediate tread blocks separated by wide circumferential grooves to enhance wet road traction and hydroplaning resistance. The tread blocks also feature variable geometry (slightly different sizes and shapes) and transverse sipes to provide the multiple biting edges necessary to help grip snow and ice to enhance winter traction without resorting to traditional metal studs. A pure silica tread compound is used to combine winter traction with high speed durability. Pirelli Winter 210 SnowSport studless winter tires meet the industry’s severe snow service requirements and are branded with the snowflake-on-the-mountain symbol. Install Pirelli Winter 210 SnowSport tires in sets of four only. Due to the traction capabilities of the Pirelli Winter 210 SnowSport, Pirelli recommends using Pirelli Winter 210 SnowSport tires only in sets of four to provide the best handling characteristics and tire performance.
