Pirelli Cinturato P7 - old passenger high-speed tire with an asymmetrical tread pattern class «High Performance», novelty, 2009. Tire wear-resistant and environmentally friendly. Provides a safe and comfortable ride at high speeds - the speed index H, V, W and Y - up to 300 km / h. Through the use of nanotechnology and hybrid materials in rubber compounds achieved a reduction in rolling resistance by 20%. Also increased by 6% divergence tires due to uniform pressure distribution in the contact patch. In wet weather, wide longitudinal grooves and winding slats in the central part effectively channel water away from the contact patch, reducing the braking distance on wet roads by 2% and 5% dry. Trajectory in turns helps to keep a continuous edge of the tire. Have a reduced level of traffic noise. Pirelli Cinturato P7 is used for OE-known car brands: Alfa Romeo (159, 147), MB (E-Class), Audi (A4, A4 allroad, A5), BMW (X1, Series 1 and 3), Volvo (C30, V40, V50, V70, V80 and S60).
Run Flat tire technology
Tires Runflat (ranflet) - a tire with reinforced sidewalls and special support elements. This technology provides the so-called protivospuskovaya additional emergency run. In case of damage, including a complete loss of air pressure, such a bus can be driven even up to 100 km (or more, depending on the vehicle) at a speed between 80 km / h. When the tire pressure loss is also prevented from jumping off the bus drive. Runflat tires all have a common symbol RSC (Runflat system component) on the sidewall. Runflat tires do not require special drives, but they are allowed to be installed only in vehicles equipped with the current system of monitoring tire pressure.
