After 22 months & 17k miles: Exceptional high speed handling and control. Extraordinary protection from hydroplaning. Excellent snow and ice performance for a non-snow/ice tire. It takes real work to break traction, even with traction-control disabled during wet weather. Do NOT confuse the Pilot Sport AS4 (High-Performance All-Season M+S rated - 45k warranty) for the Pilot Sport 4S (HP soft compound Summer "only" tire - 30k). Several of the negative reviews on here clearly suffer this confusion over the 4S.

I waited to purchase these All Season 4's because I previously had the All-Season 3+'s on my last vehicle. I wanted to try the newest version. The A/S 4 is incredible. It feels grippier and more progressive as it transitions in a slide. The grip level is incredible for an all-season tire. And they're very quiet - noticeably quieter than the A/S 3+. As an added bonus, the sidewall and tread of this tire is great looking. Little details like placing the tire warning's along the rim protector as opposed to on the sidewall and the "velvet-look" logos. I'd definitely buy these again and have recommended them quite often.

These tires lasted me 57,000 miles on my Tesla Model 3 RWD. Would probably last another 2500 miles but changing before rainy season in california. Tires are very grippy in rain and dry, but the noise and drone of tires is a bit excessive. Overall I love the performance, safety and longevity of the tire so decided to get a second pair.

I purchased 4 Michelin Pilot Sport 4S 255/45ZR20 (105Y) XL I like the tires however the date code on the tires were: 1 tire in 2017 2 tires 2018 1 tire 2019 I’m very disappointed in how old these tires are coming from Tire Rack! I’m happy with the ride. Lee was very helpful when ordering.

I no longer engage in terribly spirited driving (its been 25 years since racing school), but I still appreciate a superior sticky tire. I have also gained a fondness for a quiet , smooth ride, which you normally don't expect with a performance tire. I was therefore pleasantly surprised at how much these tires delivered all these qualities with so few of the usual compromises. For my purposes, this was an excellent choice, with much more grip than the OEM tires, and equal smoothness and very little more road noise. Unless you think you want a super stickey tire ( and are willing to pay the price in dollars and discomfort), I recommend the A/S 4. It looks like the new standard for an all season performance tire.

Got these not too long ago and they're a great daily tire. Quiet and very comfortable for a performance tire, my car is lowered too. I got these to replace my AS/3s since those were so good. The tire has excellent dry grip and very good wet grip. I haven't had a chance to test snow grip yet, but if the AS/3 was anything to go by, I am not worried about it one bit. I just had a chance to take the car to the track and the tires were great there as well. I never felt like the tires were going to let me go off track unless I wanted to, and I was full tilt out there. Managed to pass up a 350Z in my 200hp Acura and didn't get caught by the Focus RS or the Roush Mustang. That was a very twisty course where grip was key, and it never let me down. The tires lost a little grip after some very hard laps on a hot track, but I doubt any other all season would do better being pushed like that. They would have been fine after half a slow lap, and the brakes were cooking worse than the tires by that point.

Went from 17 inch To 18 Inch, huge jump in performance (both wet and dry) from the tires Ford put on my 2015 Mustang eco-boost. People told me the road noise would be an issue but quite the opposite. Black car, wheels, tires. Sorry, can't figure out how to transfer pic. from my phone (LG)

I have purchased two separate sets of All Season 4 Tires for two of my higher performance vehicles. Being Audi's they are AWD and quite heavy, these cars are known for understeer and when pushed hard you can feel the car push. Softer walled tires really feel floaty on the road in aggressive driving. Not only do these tires perform exceptionally well in regards to grip (accelerating and decelerating) their lateral grip is most impressive. These tires allow my cars to handle like they are on rails, regardless of the temperature. Being AA for traction and A for temperature they do exceptionally well when dedicated summer tires become hard and dangerous.

Purchased these AS/4 tires to replace factory Pilot Sport Cup tires at 10,002 miles. These tires are much quiter with improved ride and very good lateral grip. They will go up in smoke with a hard launch or agressive accelration out of a hard turn. However; under normal driving conditions they are great. Highly recommened to anyone daily driving a high performance sports car.

I purchased these tires so that I could drive my Vette so I wouldn't be worried about late season mountain drives. I have just over 2,000 miles on them and couldn't be more satisfied. The ride is great, the handling seems to be better and there's virtualy no road noise.
