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.

Awesome grip on hot dry days plus rain and wet weather! Porsche gt3 owner.I live in the pnw these tires have seen it all except snow and mud

Frankly I am disappointed so far. The ride quality on my 911 Turbo S is inferior to the OEM Eagle F1 Supersports

Bought tires about two months ago. Had continentals, what a difference. My 911 has a completely different and better drive.......

I’m on my second set of Michelin Pilot Sports 4S tires Love them. Tremendous Grip. Strong sidewall when cornering hard. Quiet ride

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

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.

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.
