About Pirelli P ZERO 255/40 R20 101W XL MO

Tyre Size and Fitment

The 255/40 R20 specification features a 255 mm section width, a 40% aspect ratio and a 20-inch rim diameter. The low-profile construction is designed for compatible premium passenger vehicles where precise steering response and high-speed stability are important.

Load and Speed Rating

The 101 load index corresponds to a maximum load capacity of 825 kg per tyre. The W speed rating permits speeds of up to 270 km/h under the specified load and inflation conditions.

Wet-Road Performance

The P ZERO uses three wide longitudinal grooves to efficiently evacuate water from the tread area. This design helps maintain control on wet roads and supports resistance to straight-line aquaplaning.

Dry and Wet Grip

The asymmetric tread design combines large rigid outer shoulder blocks with three solid central ribs. This construction supports precise steering response, braking and traction at higher speeds while maintaining controlled handling on both dry and wet surfaces.

Summer Performance

The P ZERO is an ultra-high-performance summer tyre developed for premium vehicles. Its tread and compound are designed to provide responsive handling, high-speed stability and strong braking performance in warm-weather driving conditions.

Comfort and Road Noise

The S-shaped tread design helps distribute pressure across the contact patch while also contributing to reduced tread noise and more even tread wear. The official European specification lists an external rolling-noise level of 72 dB, classified as B.

Mercedes-Benz MO Homologation

The MO marking identifies this tyre as a Mercedes-Benz original-equipment homologated version. This means the tyre has been developed and approved for specific Mercedes-Benz applications and should be matched to a vehicle according to the manufacturer's recommended tyre specification.
