I'm very pleased with these tires.My only concern was that they wouldn't be as quiet as others.Great handling,stopping and very quiet.

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

Bought Michelin PS4s for Camaro ZL1 , and love them ! They perform well , quiet , quick steer , awesome awesome grip !

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!

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

These tires give very good road holding performance. the only down side is the very noticeable road noise transmitted into the car interior.

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

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

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

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