Michelin Pilot Sport A/S 4 245/40ZR20 99Y XL

The Michelin Pilot Sport All Season 4 is an ultra-high-performance all-season tire for sports cars, luxury sedans and high-output electric vehicles. Michelin describes dry handling, short wet braking and reliable cold-weather traction, with forces spread evenly across the footprint to keep contact steady in aggressive maneuvers.

360-degree variable sipes with full-depth interlocking cuts create biting edges for wet and snowy conditions, Helio+ technology keeps the rubber flexible and gripping below freezing, and a Premium Touch sidewall finish gives a dark velvet texture.
