PS4S on my 911 seem to be performing well. Quieter, with good grip in the dry. Haven't had the opportunity to try wet roads. Consider these tires for your 911.

With 11,000 miles both rear tires are down to 4-5 tread wear, so need to replace them already.

Comfortable ride

I am an avid Michelin user. I have them on all of my family vehicles and on my high performance vehicles.

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

To date I have been pleased with the handling and performance of the tires. Hoping to continue that trend. Would not have any negatives to report.

Bought these a month ago for my Mazdaspeed3 and my car has never felt better. These tires bring so much control to my car, perfect for summer drives when you’re having a little “fun”. I was very surprised by how good they felt in the rain, with my previous tires I had to be a little cautious when it got wet but with these I don’t have that problem. I would definitely recommend these if you’re looking for top notch summer tires for any sports 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.

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!

I just got my first set of Michelin tires and they were these Michelin pilot sport 4 s tires. I've gotta say I was on the fence because of the price but as soon as you experience the capabilities of this tire and regret is instantly gone, it's been pouring rain the last week every day and not once has my confidence dropped while driving on these tires and in dry weather the level of performance is absolutely incredible
