I bought this set of tire about a year ago and can say they are the best All Season Sport tire on the market. The tires were purchased for my 2021 Roush Stage 3 Mustang which has 760 HP, 670 Ft. Lbs. TQ. The car can push any tire to its limits but the Pilot Sport A/S 4 handles the power in a very linear fashion. Yes, a Pilot Summer only tire would stick to the road better if I ran it on the track but that is not going to happen. For my very spirited driving I have found the Pilot A/S Sport 4 tire handle the twisting back mountain roads with ease. I highly recommend these tires for anyone who wants the best of All Season and Track only tires in one set of tires. Unless you plan on putting your car on a drag strip or the big oval this is all the tire you will ever need.

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 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 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.

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.

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 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 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!

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.

Great tires but they don't last. I'm at 46000km and they are down to the wear bars and not even three years old. Like I said, no other issues except for tread life. I would give it five stars if lasted 80000km or even 70000km . Driven on a Lincoln MKX with no aggressive driving.
