Pirelli created the P Zero Nero as one of its ultra-high performance run-flat tires built for all-season driving for sport vehicles and sedans. The impressive run-flat technology adds a new element of enhanced safety and gives an extra 50 miles at 50 mph driving ability should the tires happen to get a flat. This allows the driver the necessary time needed to get to a better location. The P Zero Nero uses a silica-enhanced compound tread and unique design with additional sipes that will increase traction during high or low temperatures and in wet or even snow covered driving conditions. The asymmetrical tread design also increases grip during quick acceleration and allows for unparalleled fast braking ability when needed.
