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.

I replaced the original tires on my 2011 Z06. I noticed an immediate smoother ride and much less noise in the car. Straight line acceleration is very similar even with the heads and cam mods. I am not easy on the car and drive aggressively when I take it out. I was considering a higher performance Michelin tire but am pleased with the All Season 4. How long they last is TBD.

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.

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

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

Purchased my third set of Michelin tires for my third different vehicle and Michelin continues to impress me with the quality and drivability with each new set of tires. This time I purchased as set of Pilot Sport All Season tires for my Buick Regal Sportback and the car drives better than new. I will put nothing but Michelin tires on all my cars from now on.

Mounted these tires on my Mazda 3 GT in May of 2021. Got about 7,000 on them now and I have been well pleased with their performance. Seems I chicken out before these things reach their limit as I have yet to have them squawk back to me during sever cornering, severe stopping, severe acceleration, ( well it's a four banger should just call it snappy acceleration).The performance is just outstanding in all conditions. I would like to find some fault with them but I have nothing to complain about. Good job big ol squeezy Michelin Man.

What a difference in the performance from my OEM tires. I put these on my Audi SQ5 replacing the "performance" tires that I had on there that only got about 10,000 miles. I had these new tires for about two months now and the performance of these tires blows away my other tires. It was very difficult to find a 21" all season performance tire at a affordable price. Today My wife drove the car on the freeway in a down pour and she felt very comfortable driving as it proved to be a tire that made the car very stable and responsive. It made this purchase worth every penny. So if you have a vehicle with a performance 21" tire I highly recommend the Michelin Pilot. Thank you Michelin for an awesome tire.

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 waited to purchase these All Season 4's because I previously had the All-Season 3+'s on my last vehicle. I wanted to try the newest version. The A/S 4 is incredible. It feels grippier and more progressive as it transitions in a slide. The grip level is incredible for an all-season tire. And they're very quiet - noticeably quieter than the A/S 3+. As an added bonus, the sidewall and tread of this tire is great looking. Little details like placing the tire warning's along the rim protector as opposed to on the sidewall and the "velvet-look" logos. I'd definitely buy these again and have recommended them quite often.
