Pirelli P Zero (PZ4) tires are high-performance summer tires that were developed based on Pirelli's experience in Formula 1 racing. These tires are designed specifically for luxurious and high-performing vehicles. They were initially introduced as factory-installed tires on certain Audi, Lamborghini, and Porsche models, but they are also available as replacement tires. It's important to note that the P Zero (PZ4) tires are not suitable for use in temperatures below 45°F (7°C) as they may develop compound cracking. This means that they should not be driven or stored in near-freezing temperatures, and they are not intended for use in snow or on icy roads. The P Zero (PZ4) tires are customized for each Original Equipment (OE) application. The tread compound is made from a special blend of silica and carbon black, which can be adjusted to meet the specific requirements of the vehicle manufacturer. This allows the tires to deliver the desired combination of grip, handling, comfort, tread life, and fuel economy. The tread design of the P Zero (PZ4) tires is asymmetrical, with variations in the outer shoulder depending on whether the tire is intended for sports cars or luxury vehicles. The outer shoulder of sports car tires is focused on dry handling, grip, and lateral stability, while the outer shoulder of luxury vehicle tires is optimized for comfort, noise reduction, and resistance to hydroplaning. The internal structure of the P Zero (PZ4) tires consists of twin steel belts reinforced by a hybrid combination of nylon and Kevlar. The tire casing is customized based on the desired performance characteristics, with options for polyester or rayon and either symmetric or asymmetric construction. This allows the tire designers to further fine-tune the tire to match the characteristics of the specific vehicle it is designed for. Some sizes of the P Zero (PZ4) tires are available with additional technologies. The Seal Inside technology includes an adhesive sealant that can seal punctures, allowing the tire to continue operating without losing air pressure. The Noise Cancelling System (PNCS) involves the application of a sound-absorbing foam to the inner liner of the tire, reducing cabin noise in the vehicle. In summary, Pirelli P Zero (PZ4) tires are high-performance summer tires developed using Pirelli's Formula 1 expertise. They are tailored to the specific needs of each vehicle manufacturer and offer a combination of performance, comfort, and safety. However, they should not be used in freezing temperatures or on snowy or icy roads. Some sizes also include additional technologies such as puncture sealing and noise reduction.
