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.

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 bought these tires to replace the Pirelli's on my Ford Explorer ST and they make the drive to Montana (over 1,000 miles one way) very pleasant! We drive multiple times from California to Montana a few times a year and absolutely love these tires. I'll definitely buy these again when they need to be replaced.

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 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 have a 2020 Type R, factory tires are not meant to driven below 5C so I have to get a set of tires for the winter. There is not much snow in the winter where I live but it's always under 5C and raining. I tried driving on winter tires and all-weather tires available for my car and they both failed to meet my expectation for wet traction. Put these PSAS4 on for couple weeks and I am very happy them. They are definitely better than the Conti DWS06 on my BMW. I drive a "sport car" the way it's meant to be driven, should not have to compromise and drive slowly because it's cold IMHO. I will drive my SUV when it snows heavily.

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.

Replaced OEM 2020 Mustang with Michelin Pilot Sports all season. Absolutely, love them. A quiet high performance tire that grips the road on tight curves. You can feel the traction grip the road when you takeoff. This tire is also a smooth riding tire. A notch above the Eagle F1 and Continental DWS 06 plus.

Purchased for a 2010 Camaro V6 driven all year round in a cold climate. For the past 3 months (December to March), they have performed excellently in cold weather (below freezing) and in light snow. I will no longer be swapping tires in the summer, and will stick with these all year round. They are superior to my previous winter tires on the car, along with the previous summer tires.
