Purchased these AS/4 tires to replace factory Pilot Sport Cup tires at 10,002 miles. These tires are much quiter with improved ride and very good lateral grip. They will go up in smoke with a hard launch or agressive accelration out of a hard turn. However; under normal driving conditions they are great. Highly recommened to anyone daily driving a high performance sports car.

Too many reports not indicating what vehicle the tires are mounted on! What good is such info? I have a new set of 245/4018 going on our 2019 RS 3, which has run 16,698 fast back roads out of a total 23,192 on current Michelin A/S3+ with no issues at all. Will report on the Pilot Sport 4S after some mileage is run at speed.

Bought these tires about a year ago and have no complaints at all!! They're much grippier than my old tires and are whisper quiet. Unfortunately, my MPG has taken a slight hit, but that's a small price to pay for much more confident braking and handling.

I just replaced Continental run-flat tires with the Pilot Sport All Season 4 (non run-flats). It is made a massive difference. The tires ride smoothly, steer precisely, braking is improved, and wet performance is so much better and confidence inspiring. A great combination of both sport and luxury. As to a number of comments about the tires being noisy, they really aren't any noisier than competitive tires or the tires predecessor, the A's 3+. I think it's just that the tone of the noises a little bit higher pitched and therefore more noticeable to some people. On the other hand, I noticed that there is no noise difference when driving on asphalt and concrete, which is unusual because most tires tend to be louder on concrete. Not so with these tires.

I live in NJ and put these on my car in October. Debated getting winter tires but wasn't sure if I needed something that extreme. Replaced the stock pilot sport 4S (also a great tire) to get ready for cold, wet, and sometimes snowy roads here in northern NJ. Have 3500 miles on them currently and couldn't be happier. Very confidence inspiring tires in the extreme cold and wet or dusting of snow and are capable in a few inches of snow on the road. MPG is down 1-2 miles and I haven't noticed the road noise that some people mention. Very happy so far.

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.

Had to replace the tires on my 2018 Civic Sport and I can't believe the difference. I previously had some “high-performance” Falken tires that weren't bad but after a couple days with the Michelin Sport A/S 4s I finally understand. This is the first Michelin performance tire I have ever driven on and my car is a completely different machine on these tires. The level of grip is superior to any tire I have ever had, even in the rain. My car feels like it is floating until I cut the wheel and suddenly it becomes glued to the blacktop. I am a very aggressive driver and understand the value of having tires you can trust on your car and I love these tires!!!

Just upgraded from run flat p zero and I instantly felt the diff in ride and very pleased with these tires so far and mine r very quiet. Will update if anything changes but my first impression I couldn't be more pleased Worth the wait on getting these because of all the back orders going on

Purchase these for all-season use in California. Rode these through the recent cyclone storm with no issues. No hydroplaning and complete confidence in braking and cornering. Ride is quieter than I thought. I drive a EV so only noise is from the tires which was not really noticeable. Only thing I would change is the lip of the tire seems to offer little protection for my brand new wheels. It sits flush with the lip of the wheel and I can already foresee curb rashes. If they can bring out the lip of the tire a bit more to protect the rim, I would give it 5 stars. Othere than that, a super high performance tire. I take off fast, corner fast, and stop fast so a high performance tire is required.

These tires have great grip even in the heaviest of rains however you pay for this with 15-20% range loss in all driving conditions in my Tesla Model 3. I normally only drive it locally but now I can't really take it on long trips because it will require charging stops.
