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 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've had the Pilot Sport 4S on my BMW 1M for about 3 months. These are outstanding. I was particularly impressed by the incredible performance and road holding in the rain. Too bad they don't make these in 285 or 295s otherwise I would've bought them for my 911 4S (would've been match made in heaven)

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 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 am not one just to skimp on tires to save some dollars or whatever “looks cool” I do my reasearch (i.e. reviews, videos, tech speech’s, etc.). After all what is the point of having a performance vehicle if you don’t go for the best in performance tires? The Michelin Pilot Sport 4s are THOSE TIRES! These things are excellent in every way. You notice the grip (and especially in the turns) right off the bat. The sidewallls look outstanding and the other edge channels to me, resemble small lightning bolts which is just another cool thing about these tires. Much quieter and smoother than other performance tires I’ve owned in the past. I’m beyond satisfied with these tires! If you’re on the fence about these, do yourself a great thing and get them! Great in turns, keep you from hydroplaning in the rain and very responsive. You get what you pay for and these are worth it. After all they are Michelin’s. And come with major Kung Fu grip! Drive with peace of mind and confidence with these! Thanks for making a great tire an excellent tire!

Just replaced the the P Zeros that came with my 2017 Porsche 911 Carrera with these tires. What a difference! Much better ride and they’re much quieter on all road surfaces. I do not track my car, so I can’t compare the two on the track. But I’m told that they handle as well if not better than the P Zeros.

Terrific grip, absolutely unacceptable noise levels. I have less than 500 miles on these and it sounds like a freight train. I have never in 30 years of driving been this frustrated with a tire choice. My Alpins are significantly quiter..to top it off I find out AFTER having em mounted that Michelin says DON'T TRACK. Did I miss that in the adverts somewhere? Pretty frustrated here. Seems some sizes make noise while others don't, just my luck!

After using PS2 for years, I switched to the PS4s. The 4s appear to have softer sidewalls which helps reduce road noise, while retaining the traction and handing. I can still experience the excitement of twisty back roads and exit ramps performance without the Mrs complaining about the road noise.

I must have driven less than 5000 km on these tires on my Audi Q7 Technik there are side bulges on 2 tires. These 2 tires have the same DOT. The 2 tires that are alright have a different DOT compared to the defective ones. I am a very careful driver. I do have additional winter tires on rims hence the mileage has been low on these tires. disappointed that an expensive tire is not made to last.
