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.

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

I bought these tires in April of this year and only put about six thousand miles on them. Cords are already showing through.

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

N rating may have reduced the road noise a bit, but not enough to justify extra cash for tires. We will see in the long run.

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.

2nd set (1st lasted 6 years w some wet track use too). Great tire and I hear they are improving it to the 5S!

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

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
