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.

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.

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

Upsized to 18" wheels & ride is even a bit softer than the AS3's on the 17" wheels. Steering at low speed is a bit heavy with the larger contact patch than the OE 215's. Good grip cold, much better when warm. Side wall flex is a big improvement in cornering.

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.

I am 60 yrs old and my wife is 67 yrs old. We bought a set of these tires 2 yrs ago for our Audi A7 and have 30,000 miles on them. They are already worn out to the red replacement stage. These tires are such a disappointment. I have always tried to buy Michelin but will be looking elsewhere now.

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.

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.

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

Just had these tires installed on my Kona Urban Edition. (Pilot Sport AS4) I am very pleased with the sporty look of these on my car. Also it was raining pretty hard while driving with these and found them very responsive with very good braking as well. (While following recommended speed limits) Another plus is that they are quiet! Very smooth ride too. Both on Highway and town driving. I feel they grip the road exceptionally well. They should serve me well for my driving needs. Highly recommend.
