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.

These tires have great grip even in the heaviest of rains however you pay for this with 15-20% range loss in all driving conditions in my Tesla Model 3. I normally only drive it locally but now I can't really take it on long trips because it will require charging stops.

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 bought 4 tire from American tire, Mr Alec recommend this tires I was so happy that I choose this tires far better than the original Tesla Model 3 tire is a 10% noisey than the original O.E.M tire. Overall is a excellent product. I would buy this tires again in the future.

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 !!! :)

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.

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 replaced my Pilot HX MXM4 93V XL, which i had for 11 years for off winter use. New Sport All Season 4 are much better on wet surface, but the noise level when driving 50-80 km/hr is quite loud...louder than the Pilot HX MXM4's, and louder than my winter tires. So I plan to keep them on this winter and will report back how well "All Season" means.

I drive a RWD P85+ Tesla Model S, which is both heavy and up until last winter had staggered 21” wheels. I was used to buying a new set of Pilot Sport 4S for the rear every 10-12k miles, which is to be expected, but not welcomed on that setup. I switch to 20” square rims front and aft, and also switched to Pilot Sport AS 4's ,245/45/ZR20 99Y, and couldn't be happier. Now that I can rotate tires life if grand. I'm used to extremely irregular wear and regular pinch flats, but I've got things nailed down now. Tire wear with theses tire is even, traction is more than adequate and tire noise is drastically reduced.

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!
