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

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.

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

Great tires, however contact patch seems to be narrower than previous generations and doesn’t look as wide and aggressive as previous. But performance/comfort/noise wise, best tires out there

Had new PZero on the C4 GTS I bought and almost immediately, LOUD AS HELL…. Even though I’ve only driven about 150 miles, feel so much better and… QUIETER..!!!

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.

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

I have had to buy 3 of these tires during the first year of ownership of my brand new car. They are expensive and nails, pot holes, bumps, etc, pop them very easy and they wear pretty quick from normal driving. I don't go to the track.

On my Porsche 2003 c4s I purchased 4 ea Pilot Sport 4s and the car runs & tracks beautiful also eliminated a lot of the Road noise I had from Previous "FALCON" 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.
