Pirelli pushes the performance envelope with the P6000. A totally innovative, freshly patented "new wave" tread design which incorporates an almost continuous, and therefore exceptionally stable, tread block running from the center to the shoulder of the tire, separated by elliptical water clearing channels running across the tread area. Born in CAD/CAM experiments, this unique tread design combines tread block stability with wet weather safety while minimizing noise generation. Pirelli's warranty does not cover tires that develop compound cracking due to use in ambient temperatures below 45° Fahrenheit (7° Celsius), so the P6000, like all summer tires, is not intended to be driven in near-freezing temperatures, through snow or on ice.With the latest generation of silica based compounds, Pirelli technologists have solved the problem of mixing silica and black fillers with synthetic polymers to provide exceptional low rolling resistance and high wet grip.The "unseen invention" of Pirelli, the P6000 casing has been specifically designed to reduce weight and to amplify the attributes of the new tread pattern and compound combination. Reduced unsprung masses, reduced rolling resistance, enhanced comfort and up to 186 mph (300 km/hr) performance in one technological package.
