Pirelli P Zero (PZ4) tires are high-performance tires that have been developed based on Pirelli's experience in Formula 1 racing. They are designed for use on exclusive and high-performing vehicles. These tires were originally used as Original Equipment on certain Audi, Lamborghini, and Porsche models, but they also have replacement tire sizes available. It's important to note that Pirelli's warranty does not cover tires that develop compound cracking when used in temperatures below 45° Fahrenheit (7° Celsius), so it is not recommended to use these tires in near-freezing temperatures, snow, or icy conditions. Each P Zero (PZ4) tire is specifically tailored to the particular vehicle it is used on. The tread compound of the tire is made of a special silica and carbon black mixture, which can be adjusted to meet the specific needs of the vehicle manufacturer. This allows the tire to deliver the desired combination of wet or dry grip, handling, comfort, tread life, and fuel economy. The tread design of the tire is asymmetric, with the outer shoulder varying depending on whether the tire is intended for use on a sports car or a luxury vehicle. The outer shoulder of a sports car tire focuses on improving dry handling, grip, and lateral stability, while the outer shoulder of a luxury vehicle tire is optimized for comfort, noise reduction, and resistance to hydroplaning. The internal structure of the P Zero (PZ4) tire consists of twin steel belts that are reinforced by a hybrid nylon and Kevlar ZeroDegree cap ply. The tire casing is customized based on the desired performance characteristics of the original equipment application. It can be made of 2-ply polyester or 1- or 2-ply rayon, and can have either symmetric or asymmetric construction. This customization allows the tire designers to further fine-tune the tire to match the characteristics of the specific vehicle it is designed for. In terms of additional features, some sizes of the P Zero (PZ4) tire come with Pirelli's Seal Inside technology. This technology involves an adhesive sealant that coats around the base of any embedded object or is drawn through the resulting hole, sealing the punctured area and preventing air pressure loss. These specific sizes are identified on the tire specifications page and in search results. Additionally, certain sizes of the Pirelli P Zero (PZ4) tire come with the Pirelli Noise Cancelling System (PNCS), which includes a layer of sound-absorbing foam attached to the inner liner of the tire. This helps to reduce cabin noise in the vehicle. These sizes are also indicated on the specifications page and in search results. Related Information: There are various technologies available to reduce tire noise, such as the Pirelli Noise Cancelling System (PNCS) used in the P Zero (PZ4) tire. These technologies are designed to enhance the comfort of the vehicle by minimizing the noise levels experienced by passengers.
