The P Zero Nero (nero Italian for black) is Pirelli's Max Performance Summer tire developed for the drivers of sports cars, sporty coupes and medium-large sedans. The P Zero Nero was developed to work harder so the driver could play harder exploiting the sporting character of their high performance car. Pirelli's warranty does not cover tires that develop compound cracking due to use in ambient temperatures below 45° Fahrenheit (7° Celsius), so the P Zero Nero, like all summer tires, is not intended to be driven in near-freezing temperatures, through snow or on ice.P Zero Nero tires feature a silica and carbon black enhanced tread compound molded into a subtle asymmetric, wide rib tread design to increase the rigidity of the tread to resist deformation and enhance grip and steering response on a variety of road surfaces while enhancing resistance to irregular wear and generating low noise levels. Circumferential grooves are optimized in their position and width to maximize dry road performance while enhancing hydroplaning resistance.The tire's internal structure features twin steel belts reinforced by zero degree nylon to complement a lightweight aramid internal structure that resists deformation at high speeds.
