Randomly worn in a section of the tire between the centre and outside edge of the tire. Only had them on my X5 for 25,000 km Always been a fan of Michelin but this is the last set I buy. I don’t even want to attempt a warranty claim because they still aren’t worth it.

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.

First replacement set of Pilot Sport AS 4 tires for my 2018 Mercedes GLS 550 lasted just over 37K miles in a little over 3 years and had hoped they would have lasted the entire 45K warranty mileage. I didn't make a warranty claim as the interior of the treads wore more than the exterior by more than the allowed difference in tread depth. We did rotate the tires as recommended by Mercedes which was every 5,000-8,000 miles. I really hope these new set of replacements will last the entire 45K mileage or more. Thanks, Clyde Toms

I bought the tires early March so far so good. I've had 2 days with light snow, 1 week of rain and a few mild days. No complains. Just bought a second set for another car + Pros: Grip, Stability, Braking, Cornering, Tread Design, Quiet, Steering Response, Visually Appealing, Comfortable,

I've had a few good tires in my life, but nothing like the wow factor of this new design. The wet traction is outstanding. This tire inspires a lot of confidence. So much technology with the tread design and the compound. I'm not looking forward to the snow, but with this tire I feel that it will not be a problem. This might be the perfect tire for the Pacific Northwest. I live in Vancouver BC and we get lots of rain. My old set of P Zeros feel like crap in comparison to the Michelin AS4. My Mustang loves these tires !!! :)

Michelin finally started making my size again for 04 SVT Cobra Mustang. They quit making an A/S for my car back in 2015 and I have to put on a BF Goodrich which bounced like rubber balls on my car, I was highly disappointed. I kept asking Michelin for my tire back again. Finally they started making these in Jul 2020. Had them put on a month again and my Mustang rides and drives like new again. It handles good and rides smooth, very little road noise. Thanks Michelin, I worked at Michelin for 36 years so I know a lot about tires and These are GREAT!!!!

I switched from PS 4 to PS All Season 4 for my 2015 Mustang (not staggered). Great tires? Yes. Very comfortable, with good performance. Before buying I had read that the AS version gives up little in dry performance - of that had been very true I would give a 5/5 testing. The compromise in all out traction is greater than I expected. But great tires that I would recommend? Definitely and I have no regret stepping down from hard core performance (the PS4 is amazing!) for more comfort and safety in lower temperatures and even light snow. Lower noise. Either tire is a great choice.

I put a set of these Michelin Pilot 4 season tires on my 2007 Corvette to replace 10 year old Pilot Super Sport Tires. There is no comparison in ride quality and road noise compared to the Pilot SS tires they replaced that tended to be harsh riding and noisy.

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 bought these tires to replace the Pirelli's on my Ford Explorer ST and they make the drive to Montana (over 1,000 miles one way) very pleasant! We drive multiple times from California to Montana a few times a year and absolutely love these tires. I'll definitely buy these again when they need to be replaced.
