The P Zero Nero All Season Run Flat is Pirelli's Ultra High Performance All-Season run-flat tire developed for sports coupes and sedans. P Zero Nero All Season Run Flat tires feature Pirelli Self-Supporting Run Flat Technology that enhances safety and convenience by providing temporary extended mobility in the event a puncture allows complete loss of air pressure. Pirelli Self-Supporting Run Flat Technology allows tires to literally "run flat" for up to 50 miles at 50 mph (80 km at 80 km/h) unless otherwise specified by the vehicle manufacturer for Original Equipment tires. The P Zero Nero All Season Run Flat is designed to deliver all-season traction and handling for drivers who operate their vehicles in America's various weather conditions, including in light snow.
This line originated as the P Zero Nero M+S Pinna line identifying Pirelli's use of a tread design that features additional sipes to enhance snow traction compared to P Zero Nero M+S tires. The sidewalls of all existing O.E. conventional and run-flat P Zero Nero M+S Pinna tires will be rebranded to add the All Season identification and will eventually be available under the P Zero Nero All Season name as the line moves forward. P Zero Nero All Season tires are fully compatible with the P Zero Nero M+S Pinna tires and may be used to replace them individually, in pairs or sets.
The P Zero Nero All Season Run Flat features a silica-enhanced tread compound blended to provide traction during high temperatures in the dry and low temperatures in the wet or snow. This compound is molded into an asymmetric tread design that features stable outside shoulder blocks combined with siped, continuous intermediate and center ribs that increase footprint rigidity to enhance dry 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. Pirelli's extended mobility solution is made possible by their MIRS computer-controlled robotized manufacturing system, a production process that assures consistency in the application of the additional sidewall reinforcements that provide the self-supporting run-flat capability.
Most run-flat tires are summer tires developed for O.E. use on global vehicle makes/models. But several manufacturers have responded to the needs of North American drivers with run-flat tires that promise year-round traction.
We tested favorites from the High Performance All-Season and Ultra High Performance All-Season categories to see if they deliver on their promise.
