The P Zero Nero (ne' ro – Italian for black) M+S Ultra High Performance All Season tire was designed specifically for the North American market to provide year-round traction and handling for cars with sporty dispositions. The P Zero Nero M+S is built using the MIRS technology manufacturing process, Pirelli's most advanced tire design and production system. The P Zero Nero M+S is Pirelli's Ultra High Performance choice for drivers who want to drive their car through America's various weather conditions, including occasional light snow. The P Zero Nero M+S features a silica-enhanced tread compound blended to provide traction during high temperatures in the dry and low temperatures in the wet or light snow. This compound is molded into an asymmetric tread design that features stable outside shoulder blocks combined with notched, continuous center ribs that increase footprint rigidity to enhance grip during acceleration and braking. Shoulder grooves and circumferential channels allow water to flow through the tread design to resist hydroplaning and enhance wet traction. The tire's internal structure includes twin steel belts to provide strength and durability on top of a polyester cord body.
