Pirelli P Zero Nero All Season. FEATURES AND BENEFITS: All weather traction; Enhanced cornering ability; Shorter braking distance; High speed driving durability; Vibration free drive; . OVERVIEW: The Pirelli P Zero Nero All Season is a performance and high performance, all season tire manufactured for passenger vehicles. Pirelli offers a 45,000 mile treadwear warranty with this model.The special silica-based tire compound combined with the asymmetric tread pattern improves the all weather traction. The special siping design grips the road well in dry, wet and even in light winter weather. The wet weather traction and hydroplaning resistance are further increased with the tread design's deep, circumferential and shoulder tread grooves that disperse water and slush from beneath the tire. This ensures a more secure year round road gripping ability.The tread pattern also upgrades the cornering and braking abilities. The asymmetric design's outside shoulder tread block sequence provides additional biting edges for a boosted cornering and maneuvering ability and power. The outer shoulder block design and the siped continuous ribs together enhance the tire footprint's rigidity. This ensures that the tire maintains constant road contact and it shortens the braking distance by creating friction at the moment of braking. It also allows the tire's acceleration to be faster, which overall upgrades the tire's performing capability.The P Zero Nero All Season's internal structure features twin steel belts on top of a polyester cord body. The twin steel belts reinforce the tire's driving durability by maintaining its optimal tire shape. As the tire does not deform under the driving pressure affecting it, it can perform to its utmost capability. The polyester cord body is a vibration absorbent structure which reduces the road vibrations felt in the vehicle's cabin by allowing the tire to closely follow the road structure. This makes the driving experience more comfortable. 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.
