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.

One of the best performance tires out there, cornering grip is extraordinary. Remember you are not buying these tires for longevity, you are buying them for performance.

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.

great tire but not very enduring. extraordinary dry/wet handling. no hydroplaning. grips curves well beyond the limits. except that after 12,000 km, only 5/32 remains. not very durable and very expensive

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.

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

While these tires had excellent performance in dry and wet, they were too fragile, i had one go out due manufactuer defect. Then another another one go out from hitting pot hole.

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

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.

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.
