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.

Have driven for one season on these tires. Love the way they roll and track true so you aren’t correcting the steering like so many other brands. A little more tire noise than the x-ice tires but excellent handelling.

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.

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.

I bought these for track days and they work great on track ,only thing my car weights a little more than the sidewalls can handle, the grip wet and dry is awesome ,I graduated them to street duty and the comfort is extrodenary

Had these tires on my Gen6 Camaro 2SS. Handling was stellar, but they were a little louder than I had hoped. The pricing has jumped considerably though.

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

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.

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
