Pirelli Winter Sottozero 3 225/40R18 Studless Winter Tire for BMW

Pirelli's 3D sipe technology is the core of what makes this tire exceptional in cold conditions. Unlike conventional siping, the interlocking 3D geometry keeps each sipe rigid under cornering loads while still flexing to bite into packed snow and ice — delivering the kind of confident turn-in and mid-corner stability BMW drivers demand. The directional double arrow tread pattern puts maximum rubber on the road surface, while high sipe density across the entire contact patch ensures grip is consistent from center to shoulder.

Wet and slushy roads are handled by two wide circumferential grooves designed specifically to force water out from beneath the tread at speed. This aggressive water evacuation significantly reduces the risk of hydroplaning during winter rain and slush — conditions that catch many performance tires off guard. The result is a tire that performs predictably across the full spectrum of cold-weather surfaces, not just dry snow.

The 225/40R18 size is a direct fitment for a wide range of BMW models including the E82, F22, F30, G20, F32, G22, E89, and G29 platforms. For owners with specific requirements, select sizes are also available with Pirelli's RunFlat construction, Noise Cancelling System (PNCS) foam lining, and SealInside puncture protection — ensuring you can spec the exact configuration your BMW calls for without sacrificing winter performance.
