Features and Benefits: Summer weather traction; Comfortable performance; High speed controllability; Pirelli P Zero (PZ4) TiresThe Pirelli P Zero (PZ4) is a performance and high performance, summer tire made for luxury and performance vehicles. This model is the original equipment tire for Audi, Lamborghini, and Porsche vehicles. Summer weather traction is promoted with this tire model. The tread design and the summer compound work together to greatly improve the overall dry and wet weather traction. This combination enables the tire's exceptional heat build-up resistance, while the better road-to-rubber ratio manages to greatly improve the surface grip. Wider circumferential grooves prevent hydroplaning in wet conditions, resulting in the tire's exceptional wet weather performance. This model offers excellent road contact levels for luxury-oriented vehicles. The outer shoulder design maintains the surface contact at all times, and prevents airwaves from entering the footprint. This greatly decreases the road vibrations and noise reaching the vehicle's cabin, preventing road disturbances from ruining the passengers' driving enjoyment. As a result, the tire offers exceptional road comfort levels. The Pirelli P Zero (PZ4) boosts its high speed controllability as well. The stronger structure with the twin steel belt inner structure and the tread design's optimized surface contact increases the model's high speed performance. Additionally, the summer compound helps to avoid heat build-up at all times. The tread design's surface contact and optimal tread elements help to upgrade the steering responsiveness and driving stability. This guarantees the driver's better control over the vehicle throughout its high speed application. This tire model was manufactured as the original equipment tire of select Mercedes-Benz Sport vehicles. 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.
