Description

Pirelli P-Zero PZ4 (285/45R21 113Y * RFT)

The BMW X7 Specialist. Run-Flat Security with Track-Inspired Precision.

The fourth-generation P-Zero (PZ4) is split into “Luxury Saloon” and “Sport” variants. This 21-inch SUV version combines the heavy-duty load capacity needed for a 2.5-ton vehicle with the surgical cornering grip of a sports car.

✨ Key 2026 Technical Features

• 🏃 Run-Flat Technology (RFT):

  Engineered with a self-supporting sidewall system. In the event of a puncture on a busy Singapore expressway, you can safely drive to a workshop without having to stop at the roadside to change a tyre—a critical safety feature for heavy family SUVs.

• 📐 BMW Star-Marked (*) Calibration:

  Unlike generic tyres, the (*) version has been “tailor-made” for BMW’s xDrive system and suspension geometry. It ensures the all-wheel-drive system operates perfectly without mechanical strain and provides the signature “connected” steering feel.

• 🏎️ Formula 1 Derived Compound:

  The tread utilizes a high-silica “Luxury Saloon” compound that provides exceptional wet-weather braking. The asymmetric design features wide longitudinal grooves that act as high-velocity pumps to eliminate hydroplaning during heavy rain.

• 🔇 S-Shape Tread Design:

  The unique s-shaped sipes are designed to optimize pressure distribution. This not only improves safety under hard braking but also minimizes rolling noise, ensuring a hushed and refined cabin environment even with a wide 285mm footprint.

• 🛡️ Reinforced XL SUV Casing:

  The Extra Load (XL) structure is built with twin steel belts reinforced by a hybrid nylon and Kevlar cap. This protects your 21-inch alloy rims against impact damage and prevents the “wallowing” feel common in large SUVs.

📊 Performance Summary
