The P Zero All Season Plus is the ultra-high-performance all-season member of Pirelli's P Zero family of tires. Designed for driving enthusiasts behind the wheels of powerful sports cars, coupes, and sedans seeking Pirelli prestige and year-round performance, the P Zero All Season Plus is meant to be driven in all seasons, even in light snow.
Pirelli P Zero All Season Plus tires feature Pirelli's advanced tread compound that combines special silica and polymers. The tread compound is molded into an all-new advanced asymmetric tread pattern with variable-sized tread elements to minimize in-vehicle noise while five distinctly designed ribs enhance performance in all weather conditions. Stable outer shoulder blocks feature a lateral siping to maximize cornering while a rigid center rib increases steering control, dry grip, and overall handling. Circumferential grooves evacuate water to resist hydroplaning, while large grooves between the blocks expel water and capture more snow. Winter siping technology in the inner blocks enhances tread stability while increasing the number of biting edges to improve snow traction.
Starting in 2016, Pirelli updated the P Zero All Season Plus compound to improve traction in wet and snowy conditions. While the benefits of the revised compound are best realized when installing a full set of four tires on a vehicle, Pirelli has indicated that tires with the new compound are mixable in any quantity with tires with the original compound.
The tire's internal structure features two steel belts reinforced by a variable-tension, spirally-wrapped nylon cap ply to optimize the footprint shape, resulting in high ride comfort, steering control, and tread wear.
