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.

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.

Best all-around performance tire, excellent in rain. They do wear quickly but that is understood with sticky compounds.. Hydroplaning resistance reduced quickly with wear, but still the only performance tire I'd trust

Replaced the Dunlop run flats that came as OEM and wow what a difference. It's like I bought a new car. Much better handling, faster and more responsive. Acceleration is noticeably better and braking is fantastic.

I bought these tires early this summer, and absolutely love them. They greatly reduced the harshness of my very stiff suspension, while being quieter and having insane levels of grip compared.

The summer with these tires has been good, however the wear is not as expected. I will probably only get another summer out of these tires. The soft compound wears very quickly in this application.

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

2015 Chevy SS. They make this 4000 lb four door feel like a light weight. Hooks off the light, great around a corner... Hands down the best I have ever had in the rain. I couldn't be happier with this tire. You guys did a great job with this one.

At the suggestion of Sipan Tire, I put these on the XKR this time. In a word: Wow. Directional, stick like glue, comfortable and quiet. I was worried that summer rated tires wouldn't do well in March in Canada. It was all for not.
