Pirelli P Zero (PZ4) tires are Max Performance Summer tires derived from Pirelli’s Formula 1 experience and developed for some of the most exclusive and highest-performing vehicles available. Initially introduced as Original Equipment on the Audi A3 and S3, Lamborghini Huracan LP 580-2 and the Porsche Boxster, Cayman and 911, the P Zero (PZ4) includes replacement tire sizes as well as original equipment fitments. Pirelli’s warranty does not cover tires that develop compound cracking due to use in ambient temperatures below 45° Fahrenheit (7° Celsius), so the P Zero (PZ4), like all summer tires, is not intended to be serviced, stored nor driven in near-freezing temperatures, through snow or on ice.
Each Original Equipment marked P Zero (PZ4) tire is tailored to the specific application. A special silica and carbon black tread compound can be adjusted according to the vehicle manufacturer’s needs to deliver the desired combination of wet or dry grip and handling, comfort, tread life and fuel economy. The tread compound is molded into an asymmetric tread design featuring an outer shoulder that differs based on whether the tire is intended for original equipment use on a sports car or a luxury vehicle, with the sports car’s outer shoulder focused on dry handling, grip and lateral stability, while the outer shoulder of a luxury vehicle tire is tuned for improved comfort, noise and lateral hydroplaning resistance. Non-original equipment P Zero (PZ4) tires feature the sports car outer shoulder design, and all versions utilize wide, circumferential grooves for efficient water evacuation and hydroplaning resistance.
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 2-ply polyester or 1- or 2-ply rayon, with either symmetric or asymmetric construction. This customization allows the tire designers to further fine-tune the tire to match the personality of the automobile for which it is engineered.
The specific tread pattern for each size P Zero (PZ4) is identified on the Specs tab, and will be listed as a clarifier when you look at Search Results.
Limited sizes of the Pirelli P Zero (PZ4) are available with Pirelli Noise Cancelling System (PNCS), which involves the manufacturer adhering a layer of sound-absorbing foam to the inner liner of the tire to reduce cabin noise in the vehicle. These sizes are identified on the Specs page and in the search results.
