The P Zero Nero All Season RFT is
Pirelli's Ultra High Performance All-Season run-flat tire developed
for sports coupes and sedans. P Zero Nero All Season RFT 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 RFT 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 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.
