Amazing tire. REPLACED 10 YEAR OLD SUMMER TIRES. THESE ARE BETTER . THERE PERFECT . ANYONE WHO GAVE BAD REVIEW PROBABLY JUST NEGATIVE PERSON.

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

Currently my new favorite tire. My 370z struggled for traction until i put a set of the PS4s on. Even in 38 degree Fahrenheit weather.

Currently running these tires for my summer set-up. Unbelievable grip, handles in the rain extremely well. Definitely would recommend to anyone.

Previous run flats felt dull and heavy. Went with the only tires that I would have on my Porsches. These are the only way to fly!

I thought the Michelin pilot super sports were the best tire money could buy. Until the new 4S came out! Highly recommend!

Usual fine grip in dry conditions (no wet testing due to lack of rain) with improved ride quality and reduced noise level.

Excellent traction, handles great and stopping distance is excellent . Very happy with the looks and the performances of these tires.

I expected excellent grip but was surprised by how quiet the 4S is. As a point of reference, previous tires include PS3, DWS06, ContiSportContact 3

Definitely noticed more grip on these tires in hot weather. Did not get a chance to autocross yet, so can't speak to that.
