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.

Like all Michelin tires that I have purchased, they meet expectations. Sport Pilot AT 4S Installed on my 2012 Honda Accord they are quiet and drive true. On the Honda I don't require the performance I demand from Sport Pilots Michelins on Carrara.

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.

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 set to replace defective Continentals on my C300. They transformed the car to a smooth well handling luxury machine. I also bought a second set for my C63. Will put them on once that backs are worn a little more. Overall fantastic tires.

The P Zeroes on my McLaren 720S were way too slippery - minimal grip especially when cold so… I had some “sideways moments with them” (unexpectably!). The Michelin P4S has cured the “problems” - great tire!

Great tires for daily or track or they stick well in cornering on dry or wet conditions other than they don't last that long and are not cheap. Good for sports car

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.

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.
