P Zero tires are Max Performance Summer tires derived from 100 years of Pirelli motorsport experience and developed for the drivers of powerful sports cars, sports coupes and high performance luxury sedans. Initially introduced as Original Equipment on the Aston Martin DB9, Audi R8, Ferrari 599 GTB Fiorano, Lamborghini Murcielago, Maserati Quattroporte Sport GT and Mercedes-Benz AMG vehicles, the P Zero lineup also includes select replacement tire sizes. 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, like all summer tires, is not intended to be driven in near-freezing temperatures, through snow or on ice.P Zero tires feature a special silica and carbon black tread compound that proves competent during the first few miles of driving when the tire is still cold, as well as consistent performance throughout the tire's life. The tread compound is molded into Pirelli's S-treme asymmetric design in which the location and width of the circumferential and lateral grooves minimize deformation to blend responsive handling, hydroplaning resistance and wet traction with dry road performance, even wear and acoustic comfort. Special nano-composites in the compound beneath the tread protect the casing from deterioration and merge sport handling with ride comfort. The tire's internal structure includes twin steel belts reinforced by polyamide cord plies and an integration of nylon and aramid cord that controls tire profile deformation and stabilizes the tread area to enhance high-speed capability and handling. Limited sizes of the P Zero are available with Pirelli Noise Cancelling System, 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.
