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.

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

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!

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

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

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

Great tires ! Now my Porsche feel much better. Tire Rack best place to buy and have your new tires installed.

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

Even wear, great performance in dry, wet, bracking & starts. Also quiet and exceptional ride quality
