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 switched from PS 4 to PS All Season 4 for my 2015 Mustang (not staggered). Great tires? Yes. Very comfortable, with good performance. Before buying I had read that the AS version gives up little in dry performance - of that had been very true I would give a 5/5 testing. The compromise in all out traction is greater than I expected. But great tires that I would recommend? Definitely and I have no regret stepping down from hard core performance (the PS4 is amazing!) for more comfort and safety in lower temperatures and even light snow. Lower noise. Either tire is a great choice.

Using these on california roads that are chewed up and spit out and they work great. No issues with it wobbling or moving or tracking wrong. Loving life with these. If I had worn struts, shocks, or bushings I would probably have issues on rough roads like other reviewer said. But probably just their car having suspension issues, no way it could be these tires Uneven cut up pavement, rough pavement, patchy road, cut up road, and partial gravel. All no issues so far, two weeks in. Cant wait for winter!

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 have an Audi SQ5 2023. I switched from my OEM Pirelli P Zero. I can report that the new Michelin are way louder above 60 MPH. They don’t corner as well. They are good under braking. I will report back when I have more miles. For the cost I wish I had gone to the Pirelli, the road noise is disappointing and unfortunately I do a lot of highway miles.

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 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.

After 22 months & 17k miles: Exceptional high speed handling and control. Extraordinary protection from hydroplaning. Excellent snow and ice performance for a non-snow/ice tire. It takes real work to break traction, even with traction-control disabled during wet weather. Do NOT confuse the Pilot Sport AS4 (High-Performance All-Season M+S rated - 45k warranty) for the Pilot Sport 4S (HP soft compound Summer "only" tire - 30k). Several of the negative reviews on here clearly suffer this confusion over the 4S.

2015 Mazda3 sTouring I have about 1000 miles on these, and was absolutely floored when I looked over the difference in fuel efficiency compared to the OEM tires. There is a drop of almost 20%! I checked the tire pressure with multiple gauges (2x analog, 1x digital), so they're not under inflated. The warehouse also inflated them with nitrogen if that makes a difference. I'm doing mostly highway commuting, so the nuances of 'better' handling may be lost on me, but they do feel like when I put my snows on- kind of mushy - on the road. After I get home (about 20 miles), the tires are very warm to the touch, even when it's raining. Don't know what they'll feel like in the summer. The warmth does make sense, if these tires have such a high rolling resistance, the energy is spent as heat. As a commute car, there really does not seem to be any difference in handling wet or dry pavement. There doesn't feel like any benefit to braking, and possibly a decrease in ability to accelerate. I am really disappointed in these tires so far. After reading all the positive reviews, I really wonder if anyone considers fuel efficiency. Maybe wearing these down to the support layers will improve fuel performance, but I'm not holding my breath for that.

Great tires on the GR Corolla, I would love to try the CrossClimate2 next. This has been great on the Florida roads, trails and even in the harsh conditions as well. People that are experiencing wear on these tires need to get their alignment checked up before mounting these tires on, my tires still look brand new after getting an alignment during the new installment. Will purchase again unless Michelin man sponsors me with a new set hehe
