PS4S on my 911 seem to be performing well. Quieter, with good grip in the dry. Haven't had the opportunity to try wet roads. Consider these tires for your 911.

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.

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.

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

I am a diehard Michelin owner. So my expectation of quality is paramount and that's why I continue to purchase this brand. Excellent ride and quiet for road noise.

After exchanging the all season tires to the summer tires, the grip and performance on summer version tires is a big difference. Soo much better. Bravo

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.

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

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.

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
