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 purchased Top of The Line Tires $$$ Expecting Top Quality & Performance. (You Get What You Pay For) As for the performance I WAS very happy with the stopping, road handling (in all weather conditions) & an over all smooth quiet ride. However the Quality / Tread Life is absolutely horrible! 3 years and only 13,000 miles later and I NEED NEW TIRES ALREADY!!! Completely UNACCEPTABLE!

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 have purchased two separate sets of All Season 4 Tires for two of my higher performance vehicles. Being Audi's they are AWD and quite heavy, these cars are known for understeer and when pushed hard you can feel the car push. Softer walled tires really feel floaty on the road in aggressive driving. Not only do these tires perform exceptionally well in regards to grip (accelerating and decelerating) their lateral grip is most impressive. These tires allow my cars to handle like they are on rails, regardless of the temperature. Being AA for traction and A for temperature they do exceptionally well when dedicated summer tires become hard and dangerous.

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!

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

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 :(

Terrible quality control. Michelin supplied 2 additional replacement sets and all 3 sets produced a vibration. Tires seen bouncing on the balancer and unacceptably high road force. 26lbs is WAY too much tolerance!!! 10 lbs is felt on low profile tires. No longer a market leader in quality.

I first owned the Michelin Pilot Sport AS3, then my tires wore down, so went to the Michelin Pilot Sport AS3+. Now I'm currently using the Michelin Pilot Sport AS4. From my very early and initial impression (under 50 miles), these tires are the best of the group thus far. I found the AS3 and AS3+ were almost identical in tread pattern, driving, comfort with a slightly higher noise level. The AS4 feels like a significant upgrade. Firstly its an entirely new tread pattern from the past 2 models. A variation of sipe thickness and patterns. It looks like it will grip better. Briefly driving on both dry and wet roads, highway and city, it delivered nicely. It already felt great with the AS3 and AS3+, so I'd expect the same with some refinement. Personally, where I really found an improvement is the noise and comfort level. This is deemed an ultra-high performance tire. Its sporty, athletic and low profile. The handing is expected to be superb and usually the tradeoff is comfort and noise. I don't know how Michelin did it, but I've found the noise level lower and the comfort level higher. It rides much more smooth and soft with less tire noise than the AS3+. My car handles even better and I feel confident with my rear wheel ride. The only concern I have is longevity and durability. Both AS3 and AS3+ were sticky tires, so they wore down quicker and sustained nail damage. I'm expecting the same with the AS4 as I believe the tire compound is the same or similar to the previous 2 models. Plus in the end, compromises are always a result of changes. I hope I'm wrong, but time will tell. Its already a superior tire and I've had a nice history of use. Michelin, if you could make a tire with added durability (less chance of nail, staple, debris causing tire damage), you'll have a true legend! In the meantime, well done on the AS4.
