I have already driven 17,118 miles with these tires and experienced my first snowstorm with them. Doing my regular maintenance rotating my tires every 5k miles and making sure my tires are properly inflated every month, I have run into 0 issues. They drove flawlessly in the snow with minimal slippage. I enjoyed them and will keep buying Michelin tires in the future.

I no longer engage in terribly spirited driving (its been 25 years since racing school), but I still appreciate a superior sticky tire. I have also gained a fondness for a quiet , smooth ride, which you normally don't expect with a performance tire. I was therefore pleasantly surprised at how much these tires delivered all these qualities with so few of the usual compromises. For my purposes, this was an excellent choice, with much more grip than the OEM tires, and equal smoothness and very little more road noise. Unless you think you want a super stickey tire ( and are willing to pay the price in dollars and discomfort), I recommend the A/S 4. It looks like the new standard for an all season performance tire.

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.

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.

Went from 17 inch To 18 Inch, huge jump in performance (both wet and dry) from the tires Ford put on my 2015 Mustang eco-boost. People told me the road noise would be an issue but quite the opposite. Black car, wheels, tires. Sorry, can't figure out how to transfer pic. from my phone (LG)

I bought a set of pilot sport AS4 to put on my car and I absolutely love them the amount of control and response difference compared to the stock tires was unbelievable and as far as grip goes I have a hard time breaking loose when I try to do it on purpose

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.

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 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.

I am hesitant to give a 5 star, because these tires on my Miata, seem to lack smooth steering. For example, when you just slightly turn the wheel, it jumps like it had difficulty going over its own tread?????, then when you turn back slightly it sticks and jumps. Very subtle, different then the OEM tires that were on the vehicle. Wish I really knew what was going on. Air pressure is what is on door jam. I may vary tire pressure and test.
