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.

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

Got these not too long ago and they're a great daily tire. Quiet and very comfortable for a performance tire, my car is lowered too. I got these to replace my AS/3s since those were so good. The tire has excellent dry grip and very good wet grip. I haven't had a chance to test snow grip yet, but if the AS/3 was anything to go by, I am not worried about it one bit. I just had a chance to take the car to the track and the tires were great there as well. I never felt like the tires were going to let me go off track unless I wanted to, and I was full tilt out there. Managed to pass up a 350Z in my 200hp Acura and didn't get caught by the Focus RS or the Roush Mustang. That was a very twisty course where grip was key, and it never let me down. The tires lost a little grip after some very hard laps on a hot track, but I doubt any other all season would do better being pushed like that. They would have been fine after half a slow lap, and the brakes were cooking worse than the tires by that point.

I've installed the Pilot Sport A/S 4 on my 1995 Camaro Z28 I've own this car since new, over the 26 yrs of its life I've had several different tires. I can honestly say that this tire lives up to the Michelin standard, awesome performance in wet traction excellent overall. If you have the opportunity to purchase these tires in your size if available just do it you won't be disappointed. Only negative thing about this tire is the availability in all sizes.

I just got a set of All Season 4s after running the previous set since 2020. Before replacing them, I took the old set to the track, and even below 2/32" tread depth, they provided remarkable grip and performance.​ The new tires feel outstanding. They're somewhat quieter— even though I never noticed that the previous set became slightly noisier as they wore, it was never intrusive. These tires inspire confidence, offering exceptional grip during spirited drives while maintaining comfort and quietness on long highway trips.​ Driving a vehicle designed for both performance and comfort, it's impressive to have a tire that doesn't compromise on either aspect. The Pilot Sport All Season 4 truly delivers on both fronts!

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!

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 waited to purchase these All Season 4's because I previously had the All-Season 3+'s on my last vehicle. I wanted to try the newest version. The A/S 4 is incredible. It feels grippier and more progressive as it transitions in a slide. The grip level is incredible for an all-season tire. And they're very quiet - noticeably quieter than the A/S 3+. As an added bonus, the sidewall and tread of this tire is great looking. Little details like placing the tire warning's along the rim protector as opposed to on the sidewall and the "velvet-look" logos. I'd definitely buy these again and have recommended them quite often.

These were quite a bit softer and quieter than the Pilot 3 + tires removed after 40,000 miles. The Pilot 4 AS felt initially like it wouldn't be the same in handling as the 3+ AS but that was totally wrong. They handle great. I would definitely buy them again.

My car seems to ride a little harder, than before. I removed Continental tires from my Mercedes C300.The ride sounds loud,if that makes since. But for the price I guess that was pretty good. Not to mention the warranty that came with them. Life of the tire balancing, rotation, etc, etc.
