The P Zero Run Flat tire is a high-performance tire designed for sports cars, sports coupes, and luxury sedans. It is developed by Pirelli, a company with a century of motorsport experience. This tire is specifically designed to provide temporary extended mobility in case of a complete loss of air pressure. It is used as Original Equipment on certain vehicle models, such as the Mini Cooper S and BMW 7 Series. It is important to note that Pirelli's warranty does not cover tires that develop compound cracking when used in temperatures below 45°F (7°C). Therefore, the P Zero Run Flat tire, like other summer tires, should not be driven in near-freezing temperatures, snow, or on ice. The P Zero Run Flat tire features a special tread compound made from silica and carbon black. This compound performs well when the tire is cold and provides consistent performance throughout its lifespan. The tire's tread design, called S-treme asymmetric, minimizes deformation and offers responsive handling, resistance against hydroplaning, and good traction on wet and dry roads. It also ensures even wear and a comfortable driving experience. The compound beneath the tread contains nano-composites that protect the tire casing from deterioration while maintaining sport handling and ride comfort. The internal structure of the P Zero Run Flat tire includes twin steel belts reinforced by polyamide cord plies. It also incorporates a combination of nylon and aramid cord to control tire profile deformation and stabilize the tread area. This enhances the tire's high-speed capability and handling. The sidewalls of the P Zero Run Flat tire have additional reinforcements that enable it to function as a self-supporting run-flat tire. It can travel at a speed of 50 mph for a distance of 50 miles (or 80 km/h for 80 km) even after a loss of air pressure. However, to take advantage of this feature, the vehicle must be equipped with a tire pressure monitoring system (TPMS) that can detect and signal changes in tire pressure. While tires labeled with MOExtended or MOE on their sidewalls do not qualify as run-flat tires, they offer similar characteristics by providing limited temporary extended mobility after a puncture results in a complete loss of air pressure. However, it is important to note that MOExtended or MOE tires do not have the same endurance in terms of speed and distance as conventional run-flat tires. Therefore, they should not be used as substitutes in situations where a traditional run-flat tire is required. To determine the appropriate tire for your vehicle, you can check the Original Equipment tire listing for your specific year, make, and model or consult your vehicle owner's manual.
