Pirelli Winter 240 Sottozero Serie II (N0). FEATURES AND BENEFITS: N0 Porsche tire; Winter traction; Enhanced handling; Shorter braking distance; Boosted cornering ability; Reduced road noise levels; . OVERVIEW: The Pirelli Winter 240 Sottozero Serie II (N0) is a high performance winter weather tire manufactured for performance vehicles.The tire was manufactured for select Porsche vehicles. The tire brings out their best performing capabilities by providing driving safety, high speed performance and great fuel efficiency. The tire is the first approved size for these vehicles. It had to pass numerous rigorous tests to receive the N0' rating, which ensures excellent quality for Porsche vehicles.The tire has superb winter weather traction and thanks to the Temperature Dynamic Compound and the Interactive Brickwall Siping design it grips the road well. The siping design promotes biting edges on ice and snow-covered road surfaces and it ensures a safer driving experience with the enhanced traction. The special circumferential and lateral grooves boost the water evacuating ability by dispersing water and slush from below the tire footprint. This upgrades the wet and winter weather traction and effectively prevents hydroplaning situations.The Temperature Dynamic Compound and the special siping design maintain road contact at all times. This ensures a safer driving experience as it improves the steering responsiveness and driving stability. The better road contact increases the driving stability as it prevents the external driving pressure from affecting the tire during the drive. The steering responsiveness and accuracy are also promoted with the constant road contact. The steering is quicker and more precise in its response to the driver's commands. The combination of the two ensure a safer driving experience by making the tire easier to control in all weather.The tire's maneuverability is ensured by the shorter braking distance and better cornering ability. The special Interactive Brickwall Siping design enhances the braking ability by providing excellent road grip in all winter weather conditions. This creates friction at the moment of braking, which shortens the braking distance. The outer shoulder tread block sequence boosts the cornering ability and power by offering additional biting edges. They firmly grip onto the road, which enhances the driving safety.The Winter 240 Sottozero Serie II (N0) offers a quiet and comfortable driving experience. The inclined grooves of the asymmetric tread design ensure reduced road noise levels heard in the vehicle's cabin while the tires are in motion. They channel the airwaves through the tire footprint, not letting them come into contact with the tread elements, which prevents road pattern noise from forming, making the drive more enjoyable. Manufacturers recommend changing tires every 10 years. As long as tires are properly stored before they are sold, the year of their manufacture will not shorten their service life.
