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.

After 85 days, this tire took on a flathead bolt. The picture does not make sense. My local tire repair center patched the tire; however, I am alert for further problems.

I bought a new Mercedes S class 11/21. Since last Spring i have replaced three of the tires because of chuck holes. They are way too fragile for use in the midwest. I experienced one failure last spring and two others this month.

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.

Absolutely the best tires I've ever had. I have pushed them to the limit and can not believe they hold the road like they do. A great road tire as the ride quality is amazing also. You feel the road but no discomfort.

exceeded the performance I expected from an all season tire. I took the chance of leaving run flats and have not been disappointed yet HIGHLY RECOMMEND and am looking forward to upgrading to cup 2's

Made my Focus RS even a better performer than it already was.. Ready for the next Targa SCCA multi-event. Good for track events, autocrosses, and daily driving. Better than some full race tires I've had in the past.

Great tires that are able to transfer >650hp to the pavement well, are very responsive in corners, quiet, and they have an outstanding mileage warranty! I highly recommend these summer tires!!

I drive a performance Tesla. These tires have significantly better wet traction than the already good PSS. road noise is quieter than PSS as well. For sure an epic tire. Nice job.

Excellent traction in dry and wet. In acceleration, braking and cornering. I have no idea how they would be in the snow and I won't be finding out. expect they wouldn't be good. Have snow tires
