Michelin Pilot Sport All Season 4

The Pilot Sport AS4 includes a W- and Y-speed rated Ultra High Performance All-Season tire member of Michelin’s Pilot family of low profile, high-speed tires developed for the drivers of high-end sports cars, sporty coupes and sedans looking for total performance. The Pilot Sport AS4 tire is designed to provide Michelin’s highest level of ultra-high all-season performance, emphasizing dry road handling and wet road grip with balanced all-season traction for occasional light snow.

Compared to the Michelin Pilot Sport A/S 3+ it replaces, the new Pilot Sport AS4 shares the same performance-oriented tread pattern, featuring a new, advanced Helio+ tread compound for increased light-snow traction.

Pilot Sport AS4 tires feature Michelin’s Helio+ Technology, which utilizes sunflower oil and Extreme Silica Technology in the tread compound to increase traction at low temperatures and on wet roads. Molded into an aggressive asymmetric tread pattern inspired by the Michelin Pilot Super Sport, its 4-, 5- or 6-rib designs* are tuned to complement tire width and feature more rubber and rigid blocks on their outboard shoulders to provide high levels of lateral grip that offer as much dry cornering capability as some competitive summer performance tires. Wide circumferential grooves help resist hydroplaning, enhancing wet traction and grip in standing water.
