I am very happy with them: Optimized the driving dynamics of my Ferrari 812SF. I can now push the car harder in a straight line and around the corners too. I gained more control and boosted my confidence driving this beast. It's definitely a tangible upgrade from the stock Pirelli that came with the car. Bravo MIKE B

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...

great tires! almost have 10k mile on em and the tread stil looks good! i dont need to worry about spinning wheels at a green light either lol

This is my third set of Michelin PS4S tires on Porsche 911 and Boxster and love them! Great tires and worth every penny!

Mounted a set of these on my Subaru WRX and can definitely say these are the best tires I've purchased. They provide the best traction without any road noise.

I have had to buy 3 of these tires during the first year of ownership of my brand new car. They are expensive and nails, pot holes, bumps, etc, pop them very easy and they wear pretty quick from normal driving. I don't go to the track.

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.

Bought two sets of Pilot Sport 4S’s and on my wife’s 335is the rears came apart with the tread separating from the sidewall on the inside of both rear tires. Alignment is perfect, proper tire pressures maintained at all times and my wife drives the car properly and carefully. I don’t understand why this lapse in quality occurred.

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 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!
