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.

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.

I have the Michelin Pilot Sport All Season 4 installed on my 2016 Mercedes S550 4Matic with staggered 19" AMG wheels. My initial impression was that the steering and braking felt more responsive with the Michelin compared to the competitor brand they replaced, but the ride wasn't as quiet or as smooth as I expected from a Michelin on an S-Class. The next morning, I leveled out the air pressure in all 4 tires to my preferred PSI which restored the comfort level. After a few weeks and many heat cycles, there is no longer any noticeable noise. More importantly the tire provides an insane amount of grip on dry and wet roads. The Michelin Pilot Sport All Season 4 paired with all wheel drive inspires confidence and encouragement for those of us who enjoy spirited driving.

I am hesitant to give a 5 star, because these tires on my Miata, seem to lack smooth steering. For example, when you just slightly turn the wheel, it jumps like it had difficulty going over its own tread?????, then when you turn back slightly it sticks and jumps. Very subtle, different then the OEM tires that were on the vehicle. Wish I really knew what was going on. Air pressure is what is on door jam. I may vary tire pressure and test.

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.

Was looking for a new set of tires for my car recently. I had a set Pilot Sport A/S 3+ and was going to have more installed but the guy at the tire shop said they had the new Pilot Sport A/S 4 and asked if I wanted those instead. He told me they were the newest latest tire so I figured why not. Immediately I noticed a lot more road noise... I mean a lot more. The A/S 3+ was quiet and smooth all around. The 4 is a tougher ride and a lot louder. Not instantly pleased with this purchase. I hope they handle well in the rain and snow—otherwise I’ll have to chalk this purchase up as a negative one and will be looking for something else in the near future.

I've installed the Pilot Sport A/S 4 on my 1995 Camaro Z28 I've own this car since new, over the 26 yrs of its life I've had several different tires. I can honestly say that this tire lives up to the Michelin standard, awesome performance in wet traction excellent overall. If you have the opportunity to purchase these tires in your size if available just do it you won't be disappointed. Only negative thing about this tire is the availability in all sizes.

I am blown away by my new AS4s!!! I have a 2009 Chevrolet Cobalt SS. I drive spiritedly and daily drive my car. I came off of Toyo Extensa hp2s and let me just give it to Michelin.There is NO comparison. I have driven only 400miles on them but the All Season 4 is one great tire! They feel so smooth on the road and highway. I feel the grip and superb steering response driving compared to what I was driving on before. Road noise is minimal and actually very quiet from what I was used to. I am now a Michelin customer for life! Thank you Michelin for developing the best all season tire I have ever driven on.

I purchased a set of pilot sport all season 4 plus 285/45 r20 y 112. I noticed that the tread design on the left of the car is pointed in an upward tread direction (^) and the right side is in the downward direction (v). All four tires say "outside" on tire wall. I have never seen a tire that has opposite directional patterns from right side of vehicle to left side of vehicle. Please shed some light on this and/or let me know if I should return to the shop that sold this set to me. All this being said, tires show exceptional grip and road confidence in dry conditions.

I replaced the original tires on my 2011 Z06. I noticed an immediate smoother ride and much less noise in the car. Straight line acceleration is very similar even with the heads and cam mods. I am not easy on the car and drive aggressively when I take it out. I was considering a higher performance Michelin tire but am pleased with the All Season 4. How long they last is TBD.
