What a difference in the performance from my OEM tires. I put these on my Audi SQ5 replacing the "performance" tires that I had on there that only got about 10,000 miles. I had these new tires for about two months now and the performance of these tires blows away my other tires. It was very difficult to find a 21" all season performance tire at a affordable price. Today My wife drove the car on the freeway in a down pour and she felt very comfortable driving as it proved to be a tire that made the car very stable and responsive. It made this purchase worth every penny. So if you have a vehicle with a performance 21" tire I highly recommend the Michelin Pilot. Thank you Michelin for an awesome tire.

I've never written a tire review in my life. I can't help but write something about these tires. I previously had another all-season tire from a certain company with a blimp and the difference between these Pilot AS4s and those are shocking. Smooth as silk ride, whisper-quiet, and traction that is amazing on my heavily tuned Audi 4.0T car!

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.

Tire has amazing qualities in which i love. Tread will not keep up the 45,000 miles in which is stated. 255/40/ZR21 & 265/40/ZR21 Are the tire sizes i own. I can not purchase Hazard Insurance due to size of tire, thankfully i have not had an instance which requires it but its good to have. Please create a tire for winter for these sizes. Much appreciated!

I bought these tires 5 days ago and they flat spot overnight. I’ve never had a tire do this to me in my life. I had high expectations for these as i have always wanted Michelins. The issue goes away when the tires warm up but the colder it gets the issue doesn’t seem to go away once it warms up.

Why dont they make this in a 225/50/18 I just got a 2017 subaru legacy 3.6R Limited and they made the pilot sport a/s 3's in that size in a W speed rating, I'm looking for new tires to improve the ride and handling and everything about my car, but why should I go with a michelin if I have to settle for the old technology in the a/s 3? The a/s 4 is the newer successor with more and better technology, I got a subaru with all wheel drive so I can run a sportier tire all year long with my geographic area with occasional snow, I might just have to settle for an all season tire without a sport focus, which I dont want to do, I want an all season with a sport focus, but why should I go with an a/s 3 when there is a newer tire in the a/s 4? The answer to that is because unfortunately the a/s 4 is not available in my size, and I don't want to go with a nonfactory size either, troubling matter for a loyal michelin fan like myself, just wondering if their are plans at all to bring the a/s 4 to the market in more sizes at all? If so, i'd be interested in possibly getting some, have not actually bought the product, my ratings are just based off of my experience with michelin products in general, which have been pretty good, really honestly interested in either the cross climate 2 in the 225/50/18 in a v speed rating or higher or the a/s 4 in a w speed rating or higher, I have no use for the cross climate suv tire in my size which is designed with too high of a load rating for my sedan which would ultimately only result in an unnecessarily harsh ride since my vehicle is somewhat lighter weight, not much tire support for my vehicle in this size from michelin unfortunately, at least no tire support in the tire models that I want :(

Installed these Pilot Sport A/S 4 about three weeks ago and coming from a previous set of the Primacy MXM4 I have to say ::::) WOW!!!! For the past two weeks we've had terrible rains in South Florida and these tires have performed outstanding, in heavy rain, light rain, no acquaplaning whatsoever. When conditions dried the tires performed awesome. The sidewall and overall structure of the tire is a bit firmer, which I like comparted to Primacy and there is no squishiness at all! The noise is very much comparable to the Primacy, I would say a very small fraction louder but not noticeable. These tires were a great buy for sure. 235/40R19

Delaminates and must be replaced before tread life. I have had 3 sets of AS3, then AS4's and ALL have delaminated in the front just where the tread meets the sidewall. I use my Corvette Grand Sport for performance driving, but these tires are rated f.or high performance. I currently have less then 4,000 miles on my tires and the fronts need replacing

Didn't even last 18k miles. Purchased in Aug 2021 and put 18k highway miles on them. They're completely treadless and I have to buy 4 new tires again. These are not cheap tires to replace. I'm livid. If I could give these negative stars, I would.

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.
