I've had my tires for about 9 months now and they're awesome!! My previous set of tires were the Continental Extremecontact DWS06. If I were to compare the two, in terms of performance and comfort, the Pilot Sport A/S 4 has been quite a bit better in the dry and wet weather...gas mileage is approximately the same for both tires. I haven't had the opportunity to drive in the snow so I don't know which tires are better. But in terms of treadwear, I would give a slight edge to the Continentals.

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.

Was looking for a new set of tires for my car recently. I had a set Pilot Sport A/S 3+ and was going to have more installed but the guy at the tire shop said they had the new Pilot Sport A/S 4 and asked if I wanted those instead. He told me they were the newest latest tire so I figured why not. Immediately I noticed a lot more road noise... I mean a lot more. The A/S 3+ was quiet and smooth all around. The 4 is a tougher ride and a lot louder. Not instantly pleased with this purchase. I hope they handle well in the rain and snow—otherwise I’ll have to chalk this purchase up as a negative one and will be looking for something else in the near future.

I've never written a tire review in my life. I can't help but write something about these tires. I previously had another all-season tire from a certain company with a blimp and the difference between these Pilot AS4s and those are shocking. Smooth as silk ride, whisper-quiet, and traction that is amazing on my heavily tuned Audi 4.0T car!

I have purchased two separate sets of All Season 4 Tires for two of my higher performance vehicles. Being Audi's they are AWD and quite heavy, these cars are known for understeer and when pushed hard you can feel the car push. Softer walled tires really feel floaty on the road in aggressive driving. Not only do these tires perform exceptionally well in regards to grip (accelerating and decelerating) their lateral grip is most impressive. These tires allow my cars to handle like they are on rails, regardless of the temperature. Being AA for traction and A for temperature they do exceptionally well when dedicated summer tires become hard and dangerous.

The specs and real performance of these tires are incredible. 255/35R21/XL 98W Front - 275/35R21/XL 103W Rear. I know My Tesla MYP can outperform 97% of the vehicles on the road. The car can do 0-60 in 3.4 seconds. Most likely your non-Tesla car cannot. I put it to the test on my daily 55 mile commute. The tires have a lot to do with this. The heavy EV and high speed rating are brilliant technology. Fully confident all weather rain/sleet /snow/ice at very high speeds. Hey Michelin Bring back Premium Touch.. love it

Using these on california roads that are chewed up and spit out and they work great. No issues with it wobbling or moving or tracking wrong. Loving life with these. If I had worn struts, shocks, or bushings I would probably have issues on rough roads like other reviewer said. But probably just their car having suspension issues, no way it could be these tires Uneven cut up pavement, rough pavement, patchy road, cut up road, and partial gravel. All no issues so far, two weeks in. Cant wait for winter!

I ordered new wheels for a Mercedes Metris van but the supplier noticed they were slightly damaged before shipping them. I ended up selecting a slightly wider wheel and noticed the Pilot Sport All Season 4 tires were available for this wider wheel. I bought them since I’ve run through a few sets on the Porsche and they were excellent. Now, do I need tires speed rated at 186 mph on a van - no - but for just a little more than a lesser tire I picked up some tires I feel confident with, especially with passengers. Ok, it’s overkill but they looking freaking great!

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.

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)
