The Cinturato P7 is Pirelli’s High Performance Summer tire developed in racing competition and adopted for road use on the Porsche 911 Carrera Turbo and Lamborghini Urraco and Countach. The Cinturato P7 was designed for drivers who want modern tire technology combined with vintage good looks and driving feel. The Cinturato P7, like all summer tires, is not intended to be serviced, stored nor driven in near- and below-freezing temperatures, through snow or on ice.
The vintage tread pattern of the Cinturato P7 is molded from a compound designed to retain performance characteristics that match vintage sports cars while also conforming to the latest environmental standards. The pattern features a solid center rib for acceleration and braking traction in addition to confident on-center feel. The circumferential grooves and diagonal notches help resist hydroplaning.
Internal construction of the Cinturato P7 features modern materials and methods, with a single-ply, rayon body casing (345/35VR15 sizes utilize a two-ply, polyester casing) and two wide, high-strength steel belts. Two polyamide reinforcement plies help stabilize the tread and provide durability and high-speed capability.
Note: Tires exposed to temperatures of 20 degrees F (-7 degrees C) or lower must be permitted to gradually return to temperatures of at least 40 degrees F (5 degrees C) for at least 24 hours before they are flexed in any manner, such as by adjusting inflation pressures, mounting them on wheels, or using them to support, roll or drive a vehicle.
Flexing of the specialized rubber compounds used in High Performance Summer tires during cold-weather use can result in irreversible compound cracking. Pirelli’s warranty does not cover tires that develop compound cracking due to use in ambient temperatures below 45° Fahrenheit (7° Celsius) because it occurs as a result of improper use or storage.
