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.

Both my car and I love these tires!

Tires performance as described. A little on the expensive side.

With 11,000 miles both rear tires are down to 4-5 tread wear, so need to replace them already.

The tires are great and perform well. But why would a OEM supply these tires on mew cars when you can't use them below 40 F?

I am an avid Michelin user. I have them on all of my family vehicles and on my high performance vehicles.

To date I have been pleased with the handling and performance of the tires. Hoping to continue that trend. Would not have any negatives to report.

Thankfully these came on my new 911 that I ordered (you can't specify tire brand) - much preferred over the Pirellis Zeros that typically come on new Porsches. On my previous Boxster, I switched from Pirelli to Michelin Pilots and was pleased. Note: I don't track my cars.

I purchased the 4S at the beginning of summer 2019. I was very happy with the added tire performance, handling and exceptional tire grip. I drive a modified 2017 Chevy SS (Sport Sedan). My satisfaction with these tires was not diminished because my warranty was reduced to 15,000 miles since I use staggered sizes front and rear. I drive fast and corner hard! And I enjoy beating youngsters in their modified cars!

Changed out from the stock run-flats, which wore out so quickly and developed a drone overtime, to the Pilot Sport 4S. Cannot imagine going back at this point. Smooth, quiet, yet far more sticky which helps boost the confidence of the vehicle! Will definitely buy more in the future.
