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.

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.

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?

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

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.

I am hesitant to give a 5 star, because these tires on my Miata, seem to lack smooth steering. For example, when you just slightly turn the wheel, it jumps like it had difficulty going over its own tread?????, then when you turn back slightly it sticks and jumps. Very subtle, different then the OEM tires that were on the vehicle. Wish I really knew what was going on. Air pressure is what is on door jam. I may vary tire pressure and test.

I brought my 2007 Mercedes Benz CLK 350 in for service inspection as the "brake pad wear" light came on recently. During the inspection, I was informed that the rear tires on the vehicle needed to be replaced. All four of the tires on the vehicle are Michelin Pilot Sport AS 4 B 225/45ZR17 94Y XL Michelin Pilot Sport AS 4 B 245/40ZR17 95Y XL Michelin Pilot Sport AS 4 B I was shocked by the news that these Michelin tires needed to be replaced, given that the vehicle is driven less than 4,000 miles a year, and the vehicle is almost never driven on the freeway, and is rarely driven above 35 mph on surface streets. I have now confirmed that these Michelin tires were installed by Big O Tires on December 7, 2020, at which time the mileage on the vehicle was 90,415. The December 7, 2020 invoice from Big O Tires states that these tires come with a warranty ("Minimum Mileage Warranty: MFG45"). This past week, on Monday, May 12, 2025, the odometer mileage was recorded as 105,606. Assuming these odometer readings are accurate (which they appear to be), this means the vehicle has been driven a total of only 15,191 miles in the 53 months since these Michelin tires were both recommended and installed on the vehicle in December, 2020. This is under 3,500 miles per year. I have never heard of tires lasting only 15,000 miles, and I certainly did not expect this of a supposed "quality tire" bearing the Michelin brand. Honestly, I thought that I was buying the best possible tires for this vehicle - and, in any event, these were the tires that were recommended by Big O Tires. During my second trip to Big O Tires on Monday, May 12, 2025, I asked about whether these tires came with a warranty, or whether the dealership (Big O Tires) or the manufacturer (Michelin) would stand behind the tires and admit the obvious - that these tires are not supposed to wear out within 15,000 miles of ordinary driving. In my discussions with Big O Tires on Monday, May 12, 2025, I was given the clear impression that there was nothing that could be done for me at the dealership (Big O Tires), and that I was free to take the matter up with the manufacturer (Michelin). This seems strange to me, since these tires were recommended and installed under a warranty by the dealership (Big O Tires), and it is the dealership that promotes the Michelin tire brand. I have now done some basic research on the internet, and it seems that many other customers have complained about these tires wearing out prematurely. The loudest complaints seem to be from customers who likewise cannot believe that Michelin tires would last as little as 15,000 miles. Conclusion The more I consider what has transpired, it is unlikely that I would rely on Big O Tires or the Michelin brand in the future, or recommend them to others.

Great tire. Extremely predictable and high levels of grip both wet or dry. Very quite on the edge of it's grip. Tread life is also amazing. Other tires don't last as long. I drive hard and I don't do silly things like smoking the tire or donuts in the intersection. No sure if it is a thoughtful engineering thing but I like how you can always tell it is time to change the tires when the ride gets rough and noisy. Even my wife who doesn't pay attention to these things notice it but I don't tell why it is so noisy and she can feel how rough the road is. The crazy thing is the grip is still there. Well as long as there is yread but I am still careful in the rain because the tread depth is there so I make sure I have room to correct.

I am blown away by my new AS4s!!! I have a 2009 Chevrolet Cobalt SS. I drive spiritedly and daily drive my car. I came off of Toyo Extensa hp2s and let me just give it to Michelin.There is NO comparison. I have driven only 400miles on them but the All Season 4 is one great tire! They feel so smooth on the road and highway. I feel the grip and superb steering response driving compared to what I was driving on before. Road noise is minimal and actually very quiet from what I was used to. I am now a Michelin customer for life! Thank you Michelin for developing the best all season tire I have ever driven on.

I bought these tires to replace the Pirelli's on my Ford Explorer ST and they make the drive to Montana (over 1,000 miles one way) very pleasant! We drive multiple times from California to Montana a few times a year and absolutely love these tires. I'll definitely buy these again when they need to be replaced.
