Pirelli P Zero (PZ4) tires are high-performance tires that have been developed using Pirelli's experience in Formula 1 racing. These tires are designed for luxury and high-performance vehicles and were initially used as original equipment for a range of cars including the Audi A3 and S3, Lamborghini Huracan LP 580-2, and Porsche Boxster, Cayman, and 911. The P Zero (PZ4) tires are available as both replacement tires and original equipment fitments. It's worth noting that Pirelli's warranty does not cover tires that develop compound cracking when used in temperatures below 45° Fahrenheit (7° Celsius). Therefore, it is recommended not to use these tires in freezing temperatures, snow, or on ice. Each P Zero (PZ4) tire marked as original equipment is customized to suit the specific requirements of the vehicle it will be used on. The tire's tread compound, which is a mixture of silica and carbon black, can be adjusted to provide the desired balance of wet and dry grip, handling, comfort, tread life, and fuel economy as per the vehicle manufacturer's needs. The tire's asymmetric tread design features a different outer shoulder depending on whether it is designed for a sports car or a luxury vehicle. The sports car version focuses on dry handling, grip, and lateral stability, while the luxury vehicle version is tuned for improved comfort, reduced noise, and better hydroplaning resistance. Non-original equipment P Zero (PZ4) tires have the same sports car design, and all versions have wide circumferential grooves to efficiently evacuate water and resist hydroplaning. The internal structure of the P Zero (PZ4) tire consists of twin steel belts reinforced by a blend of nylon and Kevlar. The tire casing can have 2-ply polyester or 1- or 2-ply rayon, depending on the desired performance characteristics for the specific vehicle application. This customization allows the tire designers to further fine-tune the tire to match the characteristics of the vehicle it is designed for. Some sizes of the P Zero (PZ4) tires come with additional technologies. The Seal Inside technology is available in limited sizes and utilizes an adhesive sealant that helps seal punctures and prevent air loss, allowing the vehicle to continue operating without losing tire pressure. The Pirelli Noise Cancelling System (PNCS) is another technology offered in limited sizes. It involves the application of a sound-absorbing foam layer to the inner liner of the tire, which helps reduce cabin noise in the vehicle. In summary, Pirelli P Zero (PZ4) tires are high-performance tires derived from Pirelli's Formula 1 experience. They are suitable for luxury and high-performance vehicles and are available as original equipment fitments and replacement tires. These tires are tailored to specific applications and feature a customized tread compound and asymmetric tread design. The tire's internal structure is reinforced for optimal performance, and additional technologies such as Seal Inside and PNCS are available in limited sizes.
