Pirelli P Zero All Season 245/55R18 103W BSW

Pirelli P Zero All Season Product Description

This listing is for new Pirelli P Zero All Season 245/55R18 103W BSW Tires. Manufacturer part number: 3952100.

The Pirelli P Zero All Season brings the legendary P Zero name—Pirelli's flagship performance family—into an ultra-high-performance tire you can run year-round. Backed by a 50,000-mile limited treadwear warranty and a UTQG rating of 500 A A, it is engineered for performance sedans, coupes, and sport crossovers whose owners demand genuine cornering grip without swapping to winter tires twice a year.

The core of its capability lies in an advanced asymmetric tread design. Large, rigid outer shoulder blocks carry heavy lateral cornering loads without rolling over, providing crisp turn-in and high-speed stability. Mechanically, circumferential phase-shifted tread blocks cancel road hum, while specialized lateral siping and deep longitudinal grooves rapidly flush standing water to prevent hydroplaning. The silica-rich tread compound retains flexibility in cold weather, avoiding the severe grip drop-off that summer compounds experience below 45°F (7°C). Select sizes feature Pirelli Noise Cancelling System™ (PNCS) acoustic foam technology or Run-Flat emergency mobility options.

Pirelli produces many sizes of this line as Original Equipment (OE) for specific manufacturers (marked on the sidewall with codes such as AO for Audi, MO for Mercedes, or Star for BMW). These OE variants are specifically tuned to match a chassis's suspension kinematics and are worth matching when replacing factory sets.

Set expectations honestly on winter conditions. It is a performance all-season, not 3PMSF severe snow certified, so while it handles cold rain, slush, and light snow, it is not a substitute for a winter tire on ice. Rotate every five thousand miles where fitments permit, and check wheel alignment upon installation to prevent inner-shoulder wear on aggressive camber setups.

Best-suited for: BMW 3 Series and 5 Series, Audi A4 and Q5, Mercedes-Benz C-Class and E-Class, Tesla Model 3 and Model Y, Porsche Macan, Genesis G70, Ford Mustang.
