Pirelli P Zero All Season. FEATURES AND BENEFITS: All weather traction; Fuel efficient drive; Longer lasting tread life; Lowered road noise levels; Enhanced cornering ability; . OVERVIEW: The Pirelli P Zero All Season is a performance and high performance, all season tire manufactured for passenger vehicles and SUVs.The tire's tread compound was made with silica to ensure safe all weather traction. The tread design grips the road well in dry, wet and winter weather and it maintains constant road grip. The special tread design features four circumferential grooves, numerous lateral grooves and a detailed siping design. These evacuate water away from the tire footprint and actively prevent hydroplaning situations. This improves the all weather driving safety greatly.The silica-enhanced tire compound also makes the tire more fuel efficient. It lowers the tire's overall weight and, by doing so, it reduces the rolling resistance. The rolling resistance is the force that determines how much energy the vehicle needs to maintain motion and this decreased resistance lessens the vehicle's fuel and energy consumption and CO2 emissions.The decreased rolling resistance also slows down the tread wear rate as the silica in the compound maintains excellent road gripping ability. Furthermore, the tread design spreads the driving pressure out across the tread surface evenly, which prevent irregular wear patterns from forming. The better fuel economy and longer lasting tread wear offer a cost-efficient and environmentally friendly drive.The tread pattern sports a variable pitch sequence that improves the comfort levels. The pitch design negates the road noise generated while the tires are in motion by creating a sound frequency that cancels them out the moment they are produced. This lowers the road noise heard by the passengers in the vehicle's cabin. The reduced road noise levels provide a quiet and comfortable driving experience in all weather.The P Zero All Season is easy to control even at high speeds. The shoulder tread block design ensures constant road contact by providing additional biting edges. These work especially well during cornering and maneuvering situations as they do not allow the tire to lose its road contact. The better road contact and cornering ability provides extra security to the all weather drive. 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.
