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.

The PS4’s are great! This is my second set from my M550i. Great dry and wet traction. They hug the road like riding on rails! I use them for summer months only. I got three summer seasons on the first set. It is my daily driver so I do put a good mile of miles on them. I’ve always been a fan of the Michelin brand. Have other brands models on the other cars in the household. I don’t notice any unusual road noises in the cabin.

There is no need to compromise on a summer tire anymore. The PS4S tire is no doubt the industry standard. Changed the complete feel of my car when i put these on. After 8000 miles, very little tread has worn. These tires also keep noise levels to a minimum, and provide the same comfort (in some cases more) of all season performance tires.

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.

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 bought these tires a few weeks ago. They are on a 2014 Porsche Boxster. I like the handling so far. I noticed that they feel loose when they are cold but seem to get stickier when warmed up. Still too early to say how they are overall as I have no experience in wet conditions yet and less than 1000 on them.

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.

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.

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.

Traction nd handling on the Michelin Pilot 4S tirs is superb. These tires replaced the original Michelin Pilot 2S on my Porsche and the 4S are stellar on dry pavement and seem to handle even better on wet pavement than than the orignal Michelin's. The 4s also provide a surprisingly quiet and comfortable ride on a high performance tire. I would highly recommend these summer tires for any high performance cars where traction and handling are paramount consideration without comromising on comfort and quiet. Very happy with the Michelin Pilot 4S so far and would highly recommend.
