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

I bought mine for an Audi A6 3.0T Quattro when the car had 52k miles on it. Absolutely loved how they handle on wet and dry roads. However, super disappointed with tread life. I have 81K on them now and one tire is almost completely bald, and the others might have 2/3K left until they look similar. Not an alignment issue either as they were rotated and tread is worn evenly. We swear by Michelin tires, and love the Defenders on our Yukon, which is why I’m being fair with 4 stars. But I will probably consider something else to replace these Pilots for this particular vehicle.

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.

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

I Purchased Top of the Line Tires $$$ Expecting Top Performance & Quality. (You Get What You Pay For) As For the Performance I WAS Very Happy with the Stopping, Road Handling (in all weather conditions) & over all Smooth Quiet Ride. HOWEVER… As far as the Quality…. Very Poor Tread Life 3 Years and only 13,000 Miles later and I ALREADY NEED NEW TIRES!! Absolutely UNACCEPTABLE!

These tires have great grip even in the heaviest of rains however you pay for this with 15-20% range loss in all driving conditions in my Tesla Model 3. I normally only drive it locally but now I can't really take it on long trips because it will require charging stops.

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.

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 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.

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.
