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!

Bought these tires in the summer and only have 300 km on them but compared to the F1's that they replaced these are very quiet and comfortable. Not quite the low profile runflat look but fills out the wheel wells better. And the F1's took forever to heat up so they slid around quite a bit just wearing off the rubber. The Michelin's are grippy after about 20 minutes after some spirited driving. Stopping is awesome and not sure what they are like in the wet as I avoid those days. I hear they are great. Looks are also a plus! I run michelins on all my vehicles as they cannot be beat.

The grip provided by these tires is astonishing compared to the other brand OEM tires they replaced. Wet and dry traction are superb. I'm also impressed by the ride quality and low noise level. My only regret is that they don't come in 16" as I also need tires for my BMW. I may have to upgrade that car to 17" wheels so I can equip it with 4 S's. Remarkable tires!

I've been a solid Michelin tire fan for almost 9 years. They are the only brand I've really come to trust. But now, I'm starting to lose that trust. I've been running Pilot Super Sports since early 2012, buying both Super Sports for summer & had a set of their All Seasons for winter, going to the Pilot® Sport A/S 3+ in 2016. ALL of their tires performed flawlessly, with great handling, a nice "feel", & long life. Then, even though I had a fairly new set of PSS's, the PS4's came out, so I got a set & had them mounted up & put them on. But now, with under 15,000 miles of use, and 6 to 7 32'nds of tread still there, there are problems. My shop guy who rotates my tires every 3/4 months is telling me that the bands inside 3 of the 4 tires are separating. He's shown me the tires & the uneven surface is easy to see. I haven't felt anything odd or heard any strange sounds though. I'm absolutely baffled by this as I've never any issues with a Michelin tire before. I don't know if it's just a bad set, or a deeper issue. Having read another review here mentioning the same kind of issue, it could be either one, or both. I love Michelin, but am not sure what to make of this.

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!

Put a set of Pilot Sport 4 S tires on my Corvette C6 this summer. Quieter on the street than I expected. On the track - wow! I pushed my 'Vette much harder on corners than I ever have before, and still feel like I haven't come close to driving these tires to their limit! Extremely solid traction and control. Can't imagine any tire that could do better.

Having owned 3 types of Michelin tires on my Audi S6 I can confidently say this tire is the benchmark for Preformance vehicles. My introduction to Michelin started with the AS3+ which was a great tire for dry, wet and occasional snow. After wearing through these tires which are now discontinued I decided to opt for the revised AS4. Unfortunately I found these tires to be quite a downgrade compared to the AS3+ for enthusiastic driving in dry conditions especially in corners. Living in California, I decided to run a summer tire year round and replaced the AS4 for a set of PS4S. These tires are fantastic. The grip these tires provide in cornering and acceleration is very impressive. The tires feels planted and confident at autobahn speeds and are responsive enough in corners to get on throttle far sooner than any other tire I have had on this car. Well done Michelin, I will be purchasing these again.

Michelin is usually my first choice, but the PS4S has a strange, imprecise feel, most noticeable when entering a fast, sweeping bend on the highway. The car feels like it yaws and wobbles before settling into a turn. The tire is also strangly loud over most highway surfaces, with an annoying, resonating howl. Definitely noisier than the older PS SuperSports were.

I remember going with my dad to get tires on the family car when I was a kid. He told me Michelin were the best tires made. On the way home he was so excited and couldn't stop pointing out to me the qualities of the tire. Now as an adult, all I mount is Michelin. Even if money's tight at the moment and new tires are needed, I mount Michelin. Ive had luxury sedans, luxury coupes, and sports cars. Currently I am running Pilot Sport 4S with a spare set in the garage just in case. Even when the tires are completely worn, they keep you fully confident. Michelin should sponsor me given how much I brag about their tires to everyone who brings up the subject.
