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.

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 thought the Michelin pilot super sports were the best tire money could buy. Until the new 4S came out! Highly recommend!

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

Definitely noticed more grip on these tires in hot weather. Did not get a chance to autocross yet, so can't speak to that.

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

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

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

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