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.

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

Absolutely love this tire, does everything extremely well regardless of weather conditions, extremely impressed.

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!

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.

I feel these tires are way better that the Goodyears I had before car is more planted and handles way better

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’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 bought my 4 tires a month ago and I was surprised with the quality! The roads even feel very padded!

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