Pirelli P Zero (PZ4) tires are high-performance tires that were developed using Pirelli's experience in Formula 1 racing. They were originally designed for select luxury and sports vehicles such as the Audi A3 and S3, Lamborghini Huracan LP 580-2, and Porsche models like the Boxster, Cayman, and 911. However, P Zero (PZ4) tires are also available as replacement options for other vehicles. It's important to note that Pirelli's warranty does not cover tires that develop compound cracking due to use in temperatures below 45° Fahrenheit (7° Celsius). As a result, these tires are not intended to be used or stored in near-freezing temperatures, snow, or icy conditions. The P Zero (PZ4) tires are specifically designed for each vehicle they are fitted on. The tread compound, which consists of silica and carbon black, can be adjusted to meet the specific needs of the vehicle manufacturer. This allows the tires to provide excellent grip, handling, comfort, tread life, and fuel economy, based on the vehicle's requirements. The tread design of the P Zero (PZ4) tires is asymmetric, with the outer shoulder designed differently depending on whether the tire is intended for a sports car or a luxury vehicle. For sports cars, the outer shoulder is optimized for dry handling, grip, and lateral stability. On the other hand, luxury vehicle tires have an outer shoulder that prioritizes comfort, noise reduction, and resistance to hydroplaning. The internal structure of the P Zero (PZ4) tires includes twin steel belts reinforced by a hybrid nylon and Kevlar ZeroDegree cap ply. The construction of the tire casing varies depending on the desired performance characteristics of the original equipment application. This allows the tire designers to customize the tire to match the characteristics of the specific vehicle it is designed for. In addition, some sizes of the P Zero (PZ4) tires are available with Pirelli's Seal Inside technology. This technology uses an adhesive sealant that can seal punctures, allowing the vehicle to continue operating without losing air pressure. There are also limited sizes of the P Zero (PZ4) tires that come with the Pirelli Noise Cancelling System (PNCS), which reduces cabin noise by incorporating a layer of sound-absorbing foam in the tire's inner liner. Overall, the Pirelli P Zero (PZ4) tires are high-performance tires that are tailored to the specific needs of luxury and sports vehicles. They offer excellent grip, handling, and comfort, while also providing options for puncture sealing and noise reduction.
