Pirelli's extended mobility solution is made possible by their MIRS computer-controlled robotized manufacturing system, a production process that assures consistency in the application of the additional sidewall reinforcements that provide the self-supporting run-flat capability. The tire's internal structure includes twin steel belts reinforced by nylon cap plies to provide high speed-durability. A robust shoulder and continuous ribs on the outboard portion of the tire enhance lateral grip on dry roads while four circumferential channels provide efficient expulsion of water from the contact patch to enhance hydroplaning resistance and wet traction. This compound is molded into an asymmetric tread design that promotes even wear, improves ride comfort and reduces noise levels. The Cinturato P7 Run Flat uses a low rolling resistance tread compound that features technologically advanced polymers to increase grip on wet and dry roads while it reduces vehicle fuel consumption and CO2 emissions. The Pirelli Ecoimpact icons on the sidewalls of Cinturato P7 Run Flat tires highlight their contribution to the environment with regards to energy efficiency, clean air, low noise and long wear. The Cinturato P7 Run Flat's unique combination of qualities have been made possible by Pirelli's Green Performance approach to developing products offering a synergy of driving pleasure, performance, safety and respect of the environment.

Pirelli's warranty does not cover tires that develop compound cracking due to use in ambient temperatures below 45° Fahrenheit (7° Celsius), so the Cinturato P7 Run Flat tires, like all summer tires, are not intended to be driven in near-freezing temperatures, through snow or on ice. Pirelli's Self-Supporting Run Flat Technology allows tires to literally 'run flat' for up to 50 miles at 50 mph (80 km at 80 km/h) unless otherwise specified by the vehicle manufacturer for Original Equipment tires. Cinturato P7 Run Flat tires feature Pirelli's Self-Supporting Run Flat Technology that enhances safety and convenience by providing temporary extended mobility in the event a puncture allows complete loss of air pressure. The Cinturato P7 Run Flat tires are Pirelli's Ultra High Performance Summer run-flat tire developed for the drivers of sport coupes, sedans and crossover vehicles.
