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.

Michelin finally started making my size again for 04 SVT Cobra Mustang. They quit making an A/S for my car back in 2015 and I have to put on a BF Goodrich which bounced like rubber balls on my car, I was highly disappointed. I kept asking Michelin for my tire back again. Finally they started making these in Jul 2020. Had them put on a month again and my Mustang rides and drives like new again. It handles good and rides smooth, very little road noise. Thanks Michelin, I worked at Michelin for 36 years so I know a lot about tires and These are GREAT!!!!

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

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 for my Mercedes S550 4matic at 80,000 miles Today at 104,000 am showing cords through 2 front tires Rotated less than a month ago and no mention of any issues. AS3 not 4 Seems like dramatic sudden failure for no apparent reason. Dealer tells me Michelin is not what they used to be as far as handling warranty issues and I will likely eat the full cost of a new set How come my rear tires did not show this wear since they had been on the front prior to this rotation?

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!

Terrible quality control. Michelin supplied 2 additional replacement sets and all 3 sets produced a vibration. Tires seen bouncing on the balancer and unacceptably high road force. 26lbs is WAY too much tolerance!!! 10 lbs is felt on low profile tires. No longer a market leader in quality.

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 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.

Replaced the old Stock Pilot Super Sports on my ‘19 Z06 Convert with a fresh set of Pilot Sport A/S 4’s. Absolutely love them. Pilot Sport A/S 4’s are rated for hot and cold ambients, dry, rain, and even snow. The perfect tire for northern state roads and highways. The Ackerman effect with tight turns, hydroplaning on rainy roads and pebble showers on the bottom of the car common with Pilot Super Sports is gone. The A/S 4’a are definitely quieter than the Pilot Super Sports. The A/S 4’s may have a bit less traction on hot dry track days but I’ll never miss it. I’d much rather have the extended driving season with the A/S 4’s . Thank you Michelin!
