The P Zero Nero GT (nero Italian for black) is Pirelli's Max Performance Summer tire developed for the drivers of sports cars, sporty coupes and medium-large sedans. As the evolution of Pirelli's earlier P Zero Nero, the P Zero Nero GT introduces their latest technological developments to enhance product performance and tread life. 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 GT, like all summer tires, is not intended to be driven in near-freezing temperatures, through snow or on ice
