Mounted a set of these on my Subaru WRX and can definitely say these are the best tires I’ve purchased. They provide the best traction without any road noise.

After exchanging the all season tires to the summer tires, the grip and performance on summer version tires is a big difference. Soo much better. Bravo

Switched from Michelin Primacy to the 4s and the ride quality and handling improvement was a nice upgrade. I live in a fairly warm climate with good road surfaces.

Good for summer/wet weather, but you should NOT use these in the extreme cold winter months we see in the Midwest. The rubber compound in these tires will harden and, potentially, crack.

Had 4s's for a little over a week now, hands down out perform all tiers I had to date. Theyou are better in cold temps by far than Pirelli p zero...Haven't listened for noise just yet.. Maserati

I bought these 2 years ago for my subaru wrx and my car goes so much better now. They are smooth, quiet, great on water. Game changer and worth every penny!

I have about 1,500 miles on these tires that I bought new. However, on one of the tires are two, approximate 1” vertical bulges protruding outward. Is this normal? Great looking/handling tires, other than the defects.

The P Zeroes on my McLaren 720S were way too slippery - minimal grip especially when cold so… I had some “sideways moments with them” (unexpectably!). The Michelin P4S has cured the “problems” - great tire!

I bought set to replace defective Continentals on my C300. They transformed the car to a smooth well handling luxury machine. I also bought a second set for my C63. Will put them on once that backs are worn a little more. Overall fantastic tires.

Upgraded from Primacy to Pilot 4S. Changed the entire character of the car. The car was fun as easily tossable on the Primacy tires, but the Pilot 4S tire significantly increased the overall performance. Turn in is particularly awesome.
