Pirelli P Zero Run Flat (PZ4) tires are derived from Pirelli's Formula 1 experience and developed for use as Original Equipment on the BMW 7 Series, Mercedes-Benz E-Class and MINI Clubman, with select replacement tire sizes also included in the lineup. P Zero Run Flat (PZ4) tires are designed to provide the convenience of temporary extended mobility in the event of complete air pressure loss. Like all summer tires, they are not intended to be driven in near-freezing temperatures, through snow or on ice. The P Zero Run Flat (PZ4) utilizes a special high silica content summer-only rubber compound that is molded into an asymmetric tread design focused on comfort, low rolling resistance, low noise and lateral hydroplaning resistance. Wide, circumferential grooves and lateral notches are utilized for efficient water evacuation at speed or while braking to improve resistance to longitudinal hydroplaning. The tire's internal structure includes twin steel belts reinforced by a hybrid nylon and Kevlar ZeroDegree cap ply. Based on the desired performance characteristics of the Original Equipment application, the tire casing will be two-ply polyester or one- or two-ply rayon, with either symmetric or asymmetric construction. With many combinations of material and orientation available during development, tire designers have the ability to fine-tune the tire's internal construction to further match the personality of the automobile for which it is engineered. The sidewalls of the P Zero Run Flat (PZ4) feature additional reinforcement to provide self-supporting run-flat capabilities of up to 50 mph for up to 50 miles (80 km/h for 80 km). Due to these restrictions, it is imperative drivers be notified when a loss in tire pressure occurs and requires the vehicle be equipped with a tire pressure monitoring system (TPMS) to detect and signal tire pressure changes.
