I've previously owned the AS3 and AS3+. These new AS4 are noticeable better. It handles and grips just as good as previous models. The improvement is in the noise and comfort level. Noise being more muted, meaning in a more comfortable ride. It's an early assessment but hope the durability and longevity will be impressive. We will see.

I've gone thru two sets of these tires with the last set going 18200 purchased 2/22 miles and are now down to the wear bars. I live in Phoenix and thought the heat was a factor. My daughter in Washington also got poor tread life out of the same model tire with a Kia sedan my car being an Audi SQ5. I'm replacing these with the Defender 2 giving Michelin another try I hope it ends up better. Also will seek some adjustments based on short tread life bit will see how that goes. All other performance for this tire were wrest they just don't last.

I just purchased a set of Michelin Pilot Sport 4 for a 2020 WRX Sport-tech RS. Replacement for the OEM Dunlop SP Sport Maxx RT which wore out prematurely (~30 000 km). I immediately noticed much less road noise with the Pilot Sport 4 compared to the Dunlop tirs. My wife even commented: "It's quiet now, like a normal car". So far noticeably more comfortable on rough roads with good handling. Hopefully, the Michelin tires are more durable. Will see how

I instantly noticed the difference in handling, performance, and traction in my 2017 Mazda 6 when I first drove on my Michelin Pilot Sport All Season 4 tires. They are awesome! They are sure-footed on winding mountain roads and provide confident stopping even on downward slopes in rainy weather. Worth every penny!

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!

Significantly louder than the HX MXM4's they replaced. Noise starts right at 40mph and gets significantly louder at highway speeds. Likely going to swap them out for another brand as this is the only Michelin tire that fits 245/50/R17. Tire handles great but I just can't deal with the noise.

This is my third set of new Michelin tires and I absolutely love them! My 18 year old car handles beautifully with them. The way they corner is smooth…there is virtually no noise from them and they “hug” the road. I have yet to drive them in the winter.

Just wanted to say these are excellent tires. The people who are having issues with these tires. I'm sorry but the person with the green SUV the tire was installed backwards. That's why your tire came off the rim. Michelin‘s tires are by far the best tires a person can buy.

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've had my tires for about 9 months now and they're awesome!! My previous set of tires were the Continental Extremecontact DWS06. If I were to compare the two, in terms of performance and comfort, the Pilot Sport A/S 4 has been quite a bit better in the dry and wet weather...gas mileage is approximately the same for both tires. I haven't had the opportunity to drive in the snow so I don't know which tires are better. But in terms of treadwear, I would give a slight edge to the Continentals.
