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.

Delaminates and must be replaced before tread life. I have had 3 sets of AS3, then AS4's and ALL have delaminated in the front just where the tread meets the sidewall. I use my Corvette Grand Sport for performance driving, but these tires are rated f.or high performance. I currently have less then 4,000 miles on my tires and the fronts need replacing

Purchased for a 2010 Camaro V6 driven all year round in a cold climate. For the past 3 months (December to March), they have performed excellently in cold weather (below freezing) and in light snow. I will no longer be swapping tires in the summer, and will stick with these all year round. They are superior to my previous winter tires on the car, along with the previous summer tires.

I have an Audi SQ5 2023. I switched from my OEM Pirelli P Zero. I can report that the new Michelin are way louder above 60 MPH. They don’t corner as well. They are good under braking. I will report back when I have more miles. For the cost I wish I had gone to the Pirelli, the road noise is disappointing and unfortunately I do a lot of highway miles.

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 originally bought the Michelin Pilot Sport A/S 3+ with a wheel and tire package in 2016. Those tires were very impressive and held up well. When I had to get new tires, the Pilot Sport A/S 4's were a no-brainer. I've had a while to give them a full and honest review. In dry conditions these tires perform just as well as any summer tire on the market. There is no lack of grip in cornering and little to no road noise depending on the condition of the road. In wet rain conditions these tires grip the road very well and keep the car grounded through corners. In snow conditions the tires do pretty well, depending how much snow. I have had some traction issues in over two inches of new snow. Obviously in these conditions, you use your best judgement and use an abundance of caution and maybe even opt for a winter tire if conditions call for it. Overall they perform well in cold conditions up to -10 below. I've never had a traction issue on cold dry roadways using these tires. Ice and snow may bring a little bit of traction issues from a dead stop, but once you are up to speed you will have enough grip to make it home. After close to two years of driving with roughy 30-45k highway miles (and not always following the reccomended tire rotation intervals) all tires are at a 7/32 tread depth and still have plenty of life left. Someone may look at the overall price point and opt for a cheaper tire option, I wouldn't call it the most "economical" option. In terms of "you get what you pay for" these are worth every penny. There's a reason you see plenty of performance manufacturers putting Pilot Sports on from the factory. It's not a gimmick. These tires will last much longer than other brands, and will continue to deliver the performance and safety you expect from a brand like Michelin.

I bought these for my charger scat pack. In a month they had 2 separations on the inside bead of the tire. First there was a vibration this is when we discovered the defect. Huge safety issue!! Then we replaced them. 4k miles another vibration and it was all 4 tires split on the inside of every tire. This could have caused a crash or even death for myself and my family!! Do Not buy!!!

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

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!

What a perfect pairing for my older QX50. We've had a rainy December in San Francisco. I usually drive my Jeep. However since installing these Pilot AS4 my old Infiniti 3.7 AWD thinks she is a sports car. My favorite feature other than the handling is wet roads and deep water at 70mph plus there is not a single hint of Hydroplaning. The wheel doesn't so much as tug. I'm talking puddles on I-580 that span 4 lanes of road. Other than a quick flick of the wiper blades; there isn't even a perception you just hit a puddle. Dry cornering at the limit at least on my Infiniti, with the driver assist off and foot on the gas hard, she drifts predictably giving lots of warning. These tires test your driving skills, not the other way around. If you are driving AWD and have 300+ HP I cannot recommend these tires more highly.
