Description

Pirelli P-Zero PZ4 (245/40R21 100Y XL * r-f)

The BMW Executive Standard. Run-Flat Security with Track-Bred Precision.

The fourth-generation P Zero (PZ4) is a “custom-fit” product, using specialized tread compounds and structural calibrations that differ depending on whether the tyre is intended for a sports car or a high-performance luxury sedan/SUV.

✨ Key 2026 Technical Features

• 🛡️ Run-Flat (r-f) Mobility:

  Features a self-supporting sidewall system. If you experience a sudden pressure loss on the expressway, you can continue driving for up to 80 km at 80 km/h. This eliminates the need for an immediate roadside change, preserving both safety and convenience.

• 🏎️ BMW (*) Custom Calibration:

  The Star-mark ensures this tyre is “tuned” for BMW. The internal belt stiffness and the tread’s lateral rigidity are calibrated to perfectly match the steering torque and weight distribution of BMW’s 21-inch wheel platforms, providing the brand’s signature direct and communicative steering.

• 🧪 Nano-Composite Tread Compound:

  The PZ4 utilizes a compound derived from Pirelli’s Formula 1 experience. It provides instantaneous grip and thermal stability, ensuring the tyre performs consistently even during high-speed, long-distance cruises in Singapore’s high-heat environment.

• 🔇 Specialized “S-Shaped” Grooves:

  The tread area includes S-shaped grooves designed to optimize the pressure distribution across the footprint. This results in lower cabin noise levels (approx. 70dB), an impressive feat for a large-diameter run-flat tyre.

• 🌧️ High-Silica Wet Performance:

  A customized inner tread design with high silica content ensures superior safety in wet conditions. It offers excellent traction and braking on rain-soaked asphalt, crucial for maintaining control during sudden tropical downpours.
