I was very excited to place these rather expensive tires, (245/40R20 Pilot Sport 4S) on my 2015 Chevy Impala LTZ. Performance and ride were fantastic for the first 2000 miles. Then they started to get to get noisy, and I mean very LOUD! They make so much noise now, you can crank the Bose sound system to 10, and you can still hear them roaring! Handling is still exceptional, but the tire noise ruins the experience. I had these tires checked, for air pressure, alignment, rotated them, and still they seem to get louder, every mile I put on them. I've got less than 3000 miles on these tires and can't wait to replace them. What a shame, I love the way they handle, but it was a costly mistake.

I switched to the PS4S from an OEM run-flat, high performance summer tire of a different brand. We went on a 1,400 kilometre trip soon afterward that included western mountain roads, where the Michelins were outstanding. They took our sports car to a new level! Bonus: they ride much better, transmit less road noise, and do not ‘tramline’ (lurch into pavement grooves and sags). They were well worth the price.

I take my '15 911 Turbo to the track 4-5 times a year. I drive in the "advanced group" at these events. The 4Ss I purchase failed in 3 track events. The outside edges of the tires delaminated to the cord! Michelin would not honor their warranty, even though these tires are advertised for occasional use at the track.

Recently Installed a new set of Pilot Sport 4 S Tires on our 2017 Dodge Charger SRT Daytona and they have made the car come alive in so many ways, to extremely good Dry and Wet traction to ultra quick breaking and performance handling! These Tires are very quite and are the worlds ultimate out on the interstate highways as we traveled from Minneapolis Minnesota to Wyoming in the ultimate ride with these tires!

I recently purchased a new vehicle. The tires it came with handled fine but were exceptionally noisy. I first tried the Pilot Sport A/S 3, which were much better, but research suggested the 4S would be quieter, and it was, considerably so. Beyond that, the 4S offer incredible handling and braking performance (both wet and dry) over the A/S 3S, so, if you can live with a bit shorter life, get the 4S. Super happy here!

I bought these these tires for a new set of rims that are on my BMW M2 Competition. The tire performance of the 4S is improved over the OEM Pilot Sports. The driving dynamics and stability at the track exceeded expectations. Excellent wear characteristics with good feedback.

I have had Nitto NT01s and Dunlops from the factory on the car. The way that 4S handle is incredible. lighter feel of the wheel, grip at every temperature, they dont have to be warm. wet weather traction is 95/100 amazing tire. will not use anything else!

I’m always amazed at how tires can completely change the driving dynamic of a car. When I purchased my Mercedes-Benz a year ago it came with the original OEM run-flat tires which were absolutely horrible. They gave such a harsh and noisy ride which one wouldn’t expect from a luxury car. However after replacing all 4 tires with the Michelin Pilot Sport 4S it now drives incredibly smooth and quiet. I feel like I have a brand new vehicle. This is how I wanted it to drive from the beginning. The handling is more predictable and solid. I even feel secure and sure-footed when driving in the rain. The thought of trading it in for a newer model crossed my mind a few times prior to getting the Michelin Pilot Sport 4S but now I’ve decided to hold on to it because it drives so well!

I bought a used car with pretty new 4S tires on them. I've not had to replace two front tires due to sidewall bubbles/tears from potholes. I know when they occurred and this level of damage should not have happened to these tires. By looking at the reviews, I can see I'm not the only one saying this. At this point just say they are track day only tires.

I bought these tires for my M240i. Swapped out all season pirelli run flat tires for these and I’m so glad I did. These tires are amazing in wet/dry conditions. I go around corners in high speeds in confidence. Also the ride is much more comfortable now. These tires grip, grip and keep gripping the road. It’s a good looking tire as well and I love how the sidewall is flat closing the gap between tire and fender. Thanks Michelin for making these tires!
