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

First time purchased. Very satisfied with how they ride. Corner great. Smooth. Great in wet weather here in Florida.

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!

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

If you need to switch the winter tire every year, this will be the best summer tire for you. If you dont switch winter tire in Canada, god bless you.

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

she got almost 55,000 mi on her original tires from the factory (replaced with same - see below) and she is happy as she can be!

Amazing tire. REPLACED 10 YEAR OLD SUMMER TIRES. THESE ARE BETTER . THERE PERFECT . ANYONE WHO GAVE BAD REVIEW PROBABLY JUST NEGATIVE PERSON.

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 !
