Thankfully these came on my new 911 that I ordered (you can't specify tire brand) - much preferred over the Pirellis Zeros that typically come on new Porsches. On my previous Boxster, I switched from Pirelli to Michelin Pilots and was pleased. Note: I don't track my cars.

These tires were standard on my 2018 Mustang GT PP package car. When test driving the car I was amazed at how quiet the the tires were in cabin at highway speeds and how well they felt over bumps and turns as I felt they were gripping and providing good feedback of the surfaces I was traversing. After 3300 miles I'm still enjoying the confidence the tires and car provide me in both wet and dry conditions and pavement types either asphalt or concrete I can apply heart pumping accelerations and maintain sure poise.

I switched to the PS4S from an OEM run-flat, high performance summer tire of a different brand. We went on a 1,400 kilometre trip soon afterward that included western mountain roads, where the Michelins were outstanding. They took our sports car to a new level! Bonus: they ride much better, transmit less road noise, and do not ‘tramline’ (lurch into pavement grooves and sags). They were well worth the price.

These came stock on my 2019 Veloster Turbo R-Spec when I bought it new last year. I'm right at 40,000 miles with 70% highway commute, 30% in town driving. The tires are at 3/32nds, well beyond the life I would expect from this type of tire. Regarding performance, read any review of the 2019 Veloster Turbo R-Spec and most, if not all will say these tires make the car great - and they're right. I'm shopping for another set as we speak.

I bought a set of these for my WRX and love them! Excellent grip in the corners, acceleration and braking. At highway speeds these tires seem to become more and more stable the faster you go. These paired with my Michelin X-Ice winter tires, I’m all set year round here in Colorado.

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 was very excited to place these rather expensive tires, (245/40R20 Pilot Sport 4S) on my 2015 Chevy Impala LTZ. Performance and ride were fantastic for the first 2000 miles. Then they started to get to get noisy, and I mean very LOUD! They make so much noise now, you can crank the Bose sound system to 10, and you can still hear them roaring! Handling is still exceptional, but the tire noise ruins the experience. I had these tires checked, for air pressure, alignment, rotated them, and still they seem to get louder, every mile I put on them. I've got less than 3000 miles on these tires and can't wait to replace them. What a shame, I love the way they handle, but it was a costly mistake.

I had these tires installed on my 2016 Dodge Challenger Hellcat. The road noise was ridiculous loud and the ride quality was terrible. I could not get any traction between 0 and 80 mph. At 80 mph on the interstate if I floor the gas the car slides all over the interstate. I tried different amounts of air pressures between 35 psi and 50 psi and nothing worked. I used these tires for 2 weeks on days between 80-90 degrees Fahrenheit and could never get any proper traction. I do not recommend these tires for any Hellcat drivers. I did not use these tires under any race conditions. Only driving around town and on the interstate.

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 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!
