Pirelli P Zero Rosso Asimmetrico (N4). FEATURES AND BENEFITS: All weather traction; Enhanced controllability; High speed durability; Reduced road noise levels; . OVERVIEW: The Pirelli P Zero Rosso Asimmetrico (N4) is a high performance summer tire manufactured for passenger and sport utility vehicles. This model is the fifth approved original equipment tire of select Porsche vehicles.The tire offers first-rate summer weather traction. The special silica-enhanced tire compound and the asymmetric tread pattern work together to increase the dry and wet weather traction. The tire is not safe to use in winter weather. Its use in colder temperatures is not recommended as the tire compound does not maintain its optimal flexibility. The wide circumferential grooves, aided by the curved grooves, effectively prevent hydroplaning when driving through deeper water. The grooves disperse water from the tire's footprint and ensure a safer summer weather driving experience.The model also promotes exceptional controllability. The asymmetric tread design with the special compact external area and the semi-slick center rib maintains a firm grip on the road surface, upgrading the steering responsiveness and the driving stability. The tire's structure is stabilized against the driving pressure affecting it, while the steering is quick and precise in its responsiveness to the driver's commands. The shoulder tread design and the circumferential grooves enhance the cornering and maneuvering capability. They promote additional biting edges that firmly grip the road surface and boost the model's performing safety.The tire has first-rate high speed performance. The tire's tread design maintains constant road contact, while its internal structure keeps the tire from deforming under the driving pressure. The internal structure features a PenTech cord that reinforces the twin steel belts. This lowers the tire's overall weight and allows the tire to perform to its best capability. The optimized tire shape and the excellent road gripping ability upgrade the high speed performance.The P Zero Rosso Asimmetrico (N4) guarantees a quiet driving experience. The special curved grooves of the tread design channel the airwaves through the tire's footprint without letting them come into contact with the tread elements. In this manner, the road noise is not generated while the tires are in motion, which ensures an enjoyable 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.
