Description
The Pirelli P Zero (PZ4) Run-Flat (RFT) with the BMW star marking (*) is an ultra-high performance summer tire that serves as original equipment for many BMW models. It is designed for luxury saloons and sports cars, focusing on high performance, safety, and a quiet, comfortable ride.
Key Features & Technology
- Run-Flat Technology (RFT): The tire features reinforced sidewalls that allow it to be driven for approximately 50 miles (80 km) at a maximum speed of 50 mph (80 km/h) after a puncture, providing temporary mobility and eliminating the immediate need for a spare tire.
- BMW Original Equipment Marking (*): The star symbol indicates that the tire has been specifically engineered in collaboration with BMW to meet their exact performance requirements, ensuring optimal integration with the vehicle’s dynamics and systems.
- Asymmetric Tread Design: The tread is split into an inner and outer section with different designs.
- The inner tread has a high silica content for enhanced safety in wet conditions and resistance to aquaplaning.
- The outer tread is designed to provide responsive handling and maximum dry grip during high-speed cornering.
- Pirelli Noise Cancelling System (PNCS): This technology often includes sound-absorbing materials (like a special polyurethane foam layer) inside the tire to significantly reduce road noise and vibrations, contributing to a quieter cabin experience.
- UTQG Rating: The tire typically has a Uniform Tire Quality Grade (UTQG) of 280 AA A.
- 280 Treadwear: Indicates expected tread life (relative to a reference standard).
- AA Traction: The highest rating for wet braking performance.
- A Temperature: The highest rating for heat resistance.
