About Pirelli P ZERO™ (PZ4)

Tyre Size and Fitment

The 265/35 R21 size features a 265 mm section width, a 35% aspect ratio and a 21-inch wheel diameter. Its low-profile design is intended for compatible high-performance vehicles using wide 21-inch wheels, with a focus on steering response, stability and precise road contact.

Load and Speed Rating

The 101 load index corresponds to a maximum load of 825 kg per tyre. The Y speed rating is designed for speeds up to 300 km/h under the applicable conditions. The XL construction provides increased load capacity for compatible high-performance vehicle applications.

Wet-Road Performance

The P ZERO (PZ4) uses a high-silica inner tread compound designed to support wet-road safety, traction and braking performance. This specific MO-S PNCS specification carries an EU wet-grip rating of A, indicating a high level of wet braking performance within the European tyre-label classification.

Dry and Wet Grip

Pirelli developed the P ZERO (PZ4) through its experience in motorsport and close collaboration with vehicle manufacturers. Its customised tread design and compound are engineered to provide stable handling, braking and traction during high-speed driving on both dry and wet roads.

Summer Performance

This is a summer Ultra-High-Performance tyre intended for warm-weather road use. Pirelli specifies that this version is not intended for severe ice and snow conditions and does not carry a 3PMSF winter marking.

Mercedes-Benz MO-S Homologation

The MO-S marking identifies a Mercedes-Benz homologated tyre specification. This marking is intended for compatible Mercedes-Benz applications where the vehicle manufacturer specifies the corresponding MO-S tyre version.

PNCS Noise-Cancelling Technology

The Pirelli Noise Cancelling System (PNCS) uses a sound-absorbing device applied to the inside of the tyre to reduce noise transmitted into the vehicle cabin. Pirelli states that PNCS technology can reduce interior tyre noise significantly compared with an equivalent tyre without the system.

Comfort and Noise

Alongside PNCS technology, the P ZERO (PZ4) uses a customised inner tread design and optimised pitch sequence to balance traction, ride comfort and acoustic performance. The EU external rolling-noise value for this specification is 70 dB with a Class A noise rating.

Production Year

This product listing is specified as 2024. The exact manufacturing date of an individual tyre should be confirmed from its DOT or production-date marking on the tyre sidewall.

Who Should Consider This Tyre?

The Pirelli P ZERO (PZ4) 265/35 R21 101Y XL MO-S PNCS is suited to drivers of compatible Mercedes-Benz and other approved high-performance applications who require a 21-inch summer tyre with XL load construction, a 300 km/h Y speed rating, Mercedes-Benz homologation and enhanced cabin-noise control through PNCS technology.
