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...

These tires are quite simply the best that have ever been manufactured. The astonishing grip, amazing ride quality and jaw dropping good looks, make this confidence inspiring tire the only logical choice for anyone with a high performance vehicle. They are honestly that good. Each year when I have to put my all seasons back on, I almost shed a tear for having to part with my Pilot Sport 4S for a few months. I would not even consider buying anything else.

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!

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.

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.

These tires are exceptional. Coming from another OEM tire and moving to these, I was hesitant at first. Would it change the car dynamics? My first order of business was to improve the wet traction, as I often found myself in rainy weather and was not entirely comfortable on the other OEM tires. They match the performance and handling, and in fact, I have much better traction now and have driven the same road with both tires. I can say that I 100% agree these are the best setup for my car.

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!

Got these three weeks ago and well satisfied! Outstanding wet and dry traction performance. Far superior to the Goodyear F1’s. I like them better than the old Pilot Sports but they also perform far better than the Goodyear F1’s. Car has an Edelbrock Blower doing 605 HP. Pilot Sport 4s is up for the opportunity! No problem.

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.
