The Michelin Pilot Sport 4 SUV (PS4 SUV) in size 275/45R20 110V XL is a premium ultra-high-performance (UHP) summer tyre engineered specifically to bring sports-car handling and absolute safety to heavy, powerful luxury SUVs.

The (VOL) marking is the most critical feature of this specific tyre: it signifies that it is officially Volvo Original Equipment homologated. Michelin co-developed this exact variant directly with Volvo engineers to perfectly match the chassis dynamics, weight distribution, and advanced safety systems of flagship Volvo models, most notably the Volvo XC90 and XC60. The (EU) designation confirms it is manufactured in Michelin's premier European facilities.
