Pirelli P Zero (PZ4) tires are high-performance summer tires that were developed using Pirelli's expertise from Formula 1 racing. They were originally made for exclusive and high-performing vehicles such as the Audi A3 and S3, Lamborghini Huracan LP 580-2, and Porsche Boxster, Cayman, and 911. These tires are available as replacements for various vehicles, and they are also used as original equipment. It is important to note that Pirelli's warranty does not cover tires that develop compound cracking when used in temperatures below 45° Fahrenheit (7° Celsius). Therefore, the P Zero (PZ4) tires, like other summer tires, should not be used in near-freezing temperatures, snowy conditions, or on icy roads. The P Zero (PZ4) tires are customized for each specific vehicle application. They use a special tread compound made of silica and carbon black, which can be adjusted to meet the specific needs of the vehicle manufacturer. This allows the tires to provide the desired performance in terms of wet and dry grip, handling, comfort, tread life, and fuel economy. The tread design of the P Zero (PZ4) tires is asymmetric and features different outer shoulders depending on whether they are intended for sports cars or luxury vehicles. The outer shoulder of sports car tires focuses on dry handling, grip, and lateral stability, while the outer shoulder of luxury vehicle tires is tuned for comfort, noise reduction, and resistance to lateral hydroplaning. All versions of the P Zero (PZ4) tires have wide grooves that help with water evacuation and resistance to hydroplaning. The internal structure of these tires is reinforced with twin steel belts and a hybrid nylon and Kevlar ZeroDegree cap ply. The tire casing is customized based on the desired performance of the original equipment application, with options for 2-ply polyester or 1- or 2-ply rayon, and symmetric or asymmetric construction. This customization allows the tire designers to match the tire's characteristics with the specific vehicle it is engineered for. Some sizes of the P Zero (PZ4) tires come with additional features. Pirelli's Seal Inside technology is available in certain sizes, which includes an adhesive sealant that is applied around the base of any embedded object or drawn through a puncture hole, effectively sealing the area and allowing the vehicle to continue operating without losing air pressure. These sizes can be identified in the specifications and search results. Furthermore, the Pirelli Noise Cancelling System (PNCS) is available in limited sizes of the P Zero (PZ4) tires. This system involves the manufacturer applying a layer of sound-absorbing foam to the inner liner of the tire, reducing cabin noise in the vehicle. The sizes that include this feature are also indicated in the specifications and search results. In conclusion, Pirelli P Zero (PZ4) tires are summer tires designed for high-performance vehicles. They are tailored to meet the specific needs of different vehicles, with a focus on grip, handling, comfort, and tread life. While they provide excellent performance in suitable conditions, it is important to avoid using them in freezing temperatures, snow, or on icy roads. Additionally, some sizes come with features such as Pirelli's Seal Inside technology and the Noise Cancelling System to enhance functionality and reduce noise in the vehicle.
