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.

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.

Put Pilot Sport 4S on my 2012 Porsche 911 Carrera S. It's a proven tire on that car. Performs great. Lots of grip in the dry, and pretty good in the wet, too. Obviously a summer tire and not made for winter or cold conditions. Very happy with the tires!

I now have 2 sets of the Pilot Sport tires on my cars. They ride nice, balanced easily, and have great handling . Through the years I have strayed from Michelin tires, mostly for cost reasons, and each time I do that, I regret it. From now on, it will be Michelin always !

Thankfully these came on my new 911 that I ordered (you can't specify tire brand) - much preferred over the Pirellis Zeros that typically come on new Porsches. On my previous Boxster, I switched from Pirelli to Michelin Pilots and was pleased. Note: I don't track my cars.

I own a 2019 BULLITT Mustang with a Stage 2 Whipple Supercharger and 825 HP. I spent a great deal of time researching and asking automotive people in the know what tire I should have on my car for when I went on the race track at AREA 27 in Oliver, BC. Time and again I was told that there was a reason why Ford put Michelin Pilot Sport 4S tires on you high performance Bullitt. Well everyone was absolutely correct. I pushed my BULLITT to the limit the entire day and the Pilot Sport 4s Michelins gave me everything I could ask for, grip, traction in the corners, predictability, feel and ride. A WIN, WIN for me and my BULLITT!!!

Pilot Sport 255 40ZR17 who would put such a tire on an old 60 muscle car. So glad I did, I drive hard corner hard and this tire performance is Exceptional to any I have used in the past. Sure I have made suspension upgrades and hope to get some tack time in. I have logged over 6000 miles and I am impressed overall, quiet predictable ride and cornering, wet performance is not great but I knew that buying a tire like this. @ 140 mph + this tire is very smooth and predictable. Hard acceleration and braking grip is superior as well.

I am not sure if I just have a bad batch but I purchased my car new in July with these tires on it and it has been garage kept in a conditioned garage. As of monday I started noticing the tires were dry rotting and had cracks all through them. Less than 3,000 miles on the car at that.. I contacted the dealership and was told there isn't much they can do its a Michelin problem... Go figure...

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!

Bought these tires yesterday. Replaced the Hankook tires that had 27,000 miles on them. They are ok tires but the PS4S are amazing. Super quiet, firm on the ground and totally changed the dynamics of my Audi TTS. Now I know I have only had them for 1 day, but had to express my enjoyment!
