Outfit your performance vehicle with the Michelin Pilot Sport All Season 4 245/40R20 99Y XL BSW, an ultra-high-performance all-season tire built for drivers who want sharp steering, strong wet and dry grip, winter confidence, and daily usability from one performance tire. This 245/40R20 Pilot Sport All Season 4 is a popular responsive fitment for select Ford Mustang Mach-E, Kia EV6 GT, Tesla Model 3 Performance, Tesla Model S, Polestar 2, BMW i4 models, plus similar performance vehicles using 20-inch wheels.
Why choose the Michelin Pilot Sport All Season 4 in 245/40R20?
Built for sport sedans, performance coupes, hot hatchbacks, and EV performance trims: The 99Y XL rating adds extra load capacity for heavier trims, performance packages, EVs, cargo, passengers, and staggered setups.
Ultra-high-performance all-season grip: The Pilot Sport All Season 4 is designed for confident performance on wet, dry, and snowy roads without moving to a dedicated summer tire.
Dynamic Response Technology: Michelin engineers the tire to distribute forces and temperatures evenly, supporting responsive handling and longer wear life.
Asymmetric performance tread: A performance-focused tread pattern with strong outer-shoulder support helps deliver lateral grip, steering precision, and planted cornering.
All-season traction details: Full-depth and interlocking sipes, biting edges, and Michelin tread-compound technology help maintain grip in rain, cold conditions, and light snow.

Customer Reviews
At times the front end and steering wheel vibrates (shakes) when I put on brakes lightly. This started happening after tire change, please advise
Better road feel, traction and comfort than OEM tires on my BMW M240i and in rain they are much better.
Actually best tires I’ve ever had
