To date I have been pleased with the handling and performance of the tires. Hoping to continue that trend. Would not have any negatives to report.

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 !

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

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

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.

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

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!

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