Michelin Pilot Sport 4 SUV ZP (*) – 275/40 R21 107Y XL TL is a high-performance summer SUV tyre engineered to meet BMW original-equipment requirements while delivering precise steering response, excellent high-speed stability, and dependable wet-road safety. The advanced asymmetric tread pattern provides strong dry grip and controlled handling on paved roads, while wide circumferential grooves ensure rapid water evacuation to reduce aquaplaning risk. Reinforced outer shoulder blocks enhance cornering stability for higher-centre-of-gravity vehicles. Michelin’s Zero Pressure (ZP) run-flat technology allows continued driving for a limited distance after air-pressure loss, and the XL reinforced casing supports increased vehicle weight. The FRV rim protection helps reduce the risk of wheel damage during kerb contact. The BMW star marking confirms full compatibility with BMW chassis tuning and electronic stability systems.
