4 Pirelli P ZERO 275/35ZR21 103Y Ultra High Performance Summer Tire PZERO UHP P2353700 / 275/35/21 / 2753521

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. 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 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.
