I went 66k miles on these tires and I am beyond happy with these tires. They did well in the rain, rough roads, I highly recommend these tires.

Had continental DWS-06 on my wrx and switched to Michelin Pilot Sport All Season 4. Didn’t expect much and boy was I wrong! On ramps and corners are like being on rails! I literally can go so much faster around corners and no give, no noise, these tires never miss a beat! These are better than the Pilot Super Sport that I have on my BMW, and these are suitable for year round performance. I was considering several options and brands, but in the end I relied on my past experiences with Michelin and went with these. So glad I did, I’m never looking back. Love the look of these and love how they perform. Now I can see why they’re OE on the C8 vette amazing product Michelin, thanks for living up to your reputation (again!)

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 purchased a set of pilot sport all season 4 plus 285/45 r20 y 112. I noticed that the tread design on the left of the car is pointed in an upward tread direction (^) and the right side is in the downward direction (v). All four tires say "outside" on tire wall. I have never seen a tire that has opposite directional patterns from right side of vehicle to left side of vehicle. Please shed some light on this and/or let me know if I should return to the shop that sold this set to me. All this being said, tires show exceptional grip and road confidence in dry conditions.

Significantly louder than the HX MXM4's they replaced. Noise starts right at 40mph and gets significantly louder at highway speeds. Likely going to swap them out for another brand as this is the only Michelin tire that fits 245/50/R17. Tire handles great but I just can't deal with the noise.

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!

I've had a few good tires in my life, but nothing like the wow factor of this new design. The wet traction is outstanding. This tire inspires a lot of confidence. So much technology with the tread design and the compound. I'm not looking forward to the snow, but with this tire I feel that it will not be a problem. This might be the perfect tire for the Pacific Northwest. I live in Vancouver BC and we get lots of rain. My old set of P Zeros feel like crap in comparison to the Michelin AS4. My Mustang loves these tires !!! :)

There is a reason OEMs choose Michelin. The Tesla model S must have smooth, quiet tires that absorb various road imperfections and maintain good handling characteristics. Road noise is a big concern when driving a vehicle that has no drivetrain noise.

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

I put these tires on my 2017 VW GTI SE as a replacement for the Pilot Sport AS3+ that I had on there for the past couple of years. I loved the AS3+, the car had really great grip and it handled like it was on rails. The steering feel and turn in was very sharp and there was almost no lean in corners. The AS4 has somewhat better ride quality than the AS3+ and great grip but the sharp cornering feel and confidence in handling curves isn't there as with the AS4. It feels more like a grand touring tire with a grippier compound whereas the AS3+ feels more like a performance tire with the ability to be used in cold weather and light snow.
