Pirelli 265/35 R20 99Y P Zero PZ4 MO1 2024

Pirelli P Zero PZ4 265/35 R20 99Y XL MO1 2024 is an ultra-high-performance summer tyre developed specifically for compatible premium vehicles using the Mercedes-Benz MO1 original-equipment specification. With a 265 mm section width, 35-series profile and 20-inch rim diameter, this tyre combines precise steering response with strong dry and wet-road performance. The 99Y service description provides a maximum load index of 775 kg per tyre and a Y speed rating up to 300 km/h under applicable conditions.

Tread Design and Steering Response

The P Zero PZ4 features an asymmetric tread design developed to provide precise steering and stable road contact. Its 265 mm footprint and low 35-series profile support responsive turn-in, accurate directional control and confident cornering during performance-oriented driving.

Dry-Road Handling and Cornering

Pirelli developed the P Zero PZ4 as a UHP tyre for premium performance vehicles, with a tread compound and construction focused on dry-road grip, braking and handling. The low-profile sidewall helps deliver a direct steering feel and stable behaviour through corners.

Wet-Road Performance

The tread incorporates a high-silica compound and dedicated internal tread design to support wet-road traction and braking. Pirelli lists this exact MO1 configuration with an A wet-grip classification, providing strong wet-weather performance when the tyre is correctly inflated and maintained.

High-Speed Stability and Comfort

The P Zero PZ4 is engineered for high-speed driving, combining its reinforced XL construction with a Y speed rating and performance-focused tread design. Pirelli also specifies an external rolling-noise rating of 69 dB for this configuration, supporting comparatively controlled exterior noise levels.

Mercedes-Benz MO1 Original-Equipment Specification

The MO1 marking identifies this tyre as a Mercedes-Benz original-equipment specification developed for vehicle-specific requirements. The MO1 version should therefore be selected when it matches the vehicle manufacturer's approved fitment, rather than being treated as interchangeable with every other 265/35 R20 P Zero PZ4 variant.

Load Capacity and Speed Rating

The 99 load index corresponds to a maximum load of 775 kg per tyre. The Y speed rating corresponds to a maximum rated speed of 300 km/h under the applicable load and inflation conditions. XL construction identifies the reinforced load version of this tyre.

Who Should Consider This Tyre?

Pirelli P Zero PZ4 265/35 R20 99Y XL MO1 is intended for compatible premium and performance vehicles requiring the Mercedes-Benz MO1 specification. It is well suited to drivers seeking precise steering, strong dry and wet grip, high-speed stability and responsive handling from a 20-inch summer performance tyre.
