Michelin Pilot Sport All Season 4 AC
Ultra-high performance is beautifully blended with all-season reliability and longevity with Michelin’s Pilot Sport All Season 4 AC tire.
This “acoustic” edition gives drivers the noise reduction features that make it even easier to enjoy your next road trip, commute or track day experience!
Michelin Pilot Sport All Season 4 AC
Built upon the already prestigious foundations of the All Season 3 and A/S 3+, the Pilot Sport All Season 4 AC delivers both wet and dry road traction in residential, highway and track conditions.
The PSAS4 AC even offers surprisingly good grip in wintry weather conditions. With its perfect mixture of traction, handling, performance, reduced tire and road noise, tread life expectancy and all-season durability this tire gives more than it takes.
Chevrolet likes its performance so much that they chose it as their OE all-season option for its launch of mid-engine Corvette!
Other exceptional performance features of the Michelin Pilot Sport All Season 4 AC include:
- MichelinⓇ Acoustic Technology significantly reduces interior noise by approximately 20%.
- Helio+ Technology uses advanced rubber compound to maintain flexibility and maximum traction even in frigid temperatures.
- 360 degree variable siping technology adds biting edges to contact patch for augmented wet and light snow traction.
- Sporty asymmetrical tread pattern gives extreme lateral grip and responsive handling in dry conditions.
- Race-inspired silica enhanced tread compound sticks to slick surfaces.
- Biting edges in tread grooves grabs onto loose snow for controlled starting and stopping in harsh winter conditions.

Pilot Sport All Season 4 AC Customer Reviews
Model Y
These were the same tires that came with my Tesla Model Y Performance. The original tires lasted almost 39,000 miles and probably would have gone over 40,000. The tire is long lasting, provides good road and steering feel, is fairly quiet and rides smoothly. Tesla’s rear suspension is the problem, not the tires.
