The Pirelli P Zero (PZ4) tires are high-performance summer tires that were developed using Pirelli's experience in Formula 1 racing. They are designed for exclusive and high-performance vehicles. Originally, they were used as original equipment on certain Audi, Lamborghini, and Porsche models, but now they are available as replacement tires as well. It's important to note that Pirelli's warranty does not cover tires that develop compound cracking in temperatures below 45°F (7°C), so these tires should not be used in near-freezing temperatures, snow, or on icy roads. Each P Zero (PZ4) tire that is marked as original equipment is specifically tailored for a particular vehicle application. The tread compound of the tire can be adjusted according to the needs of the vehicle manufacturer, balancing wet and dry grip, handling, comfort, tread life, and fuel economy. The tread design is also asymmetrical, with the outer shoulder of the tread varying depending on whether the tire is intended for a sports car or a luxury vehicle. The sports car design focuses on dry handling and grip, while the luxury vehicle design prioritizes comfort, noise reduction, and hydroplaning resistance. Non-original equipment P Zero (PZ4) tires have the sports car design. All versions of the tire have wide grooves to efficiently evacuate water and resist hydroplaning. The internal structure of the P Zero (PZ4) tires includes twin steel belts reinforced by a combination of nylon and Kevlar. The tire's casing can be customized with different materials and construction techniques, such as polyester or rayon, and either symmetric or asymmetric construction. This customization allows the tire designers to fine-tune the tire to match the characteristics of the specific vehicle it is designed for. It's important to note that certain sizes of the P Zero (PZ4) tires come with additional technologies. Pirelli's Seal Inside technology is available in limited sizes, which involves an adhesive sealant that seals punctures and allows the vehicle to continue operating without losing air pressure. The Pirelli Noise Cancelling System (PNCS) is also available in limited sizes, where a layer of sound-absorbing foam is added to the inner liner of the tire to reduce cabin noise in the vehicle. In summary, the Pirelli P Zero (PZ4) tires are high-performance summer tires that were developed using Pirelli's expertise in Formula 1 racing. They are designed for exclusive and high-performance vehicles and come in both original equipment and replacement tire sizes. The tires are tailored for specific vehicle applications, with a focus on grip, handling, comfort, and tread life. The internal structure of the tires is reinforced for durability, and there are additional technologies available in some sizes to enhance puncture resistance and reduce cabin noise. However, it's important to follow the manufacturer's guidelines regarding temperature usage and not to drive the tires in near-freezing temperatures, snow, or on icy roads.
