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.

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

Comfortable ride

This is my third set of Michelin PS4S tires on Porsche 911 and Boxster and love them! Great tires and worth every penny!

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.

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

Great tires, definitely lets my vehicle push its limits, had PZero’s before, the wet and cold traction is far superior, once the tires are warmed up, they perform similar under optimal conditions. I don’t understand why people with baseline cars are buying these tires. You’re Mitsubishi/Mazda/Lexus isn’t powerful enough to justify these… Base line cars don’t need high performance tires, what clowns…

Put Pilot Sport 4S on my 2012 Porsche 911 Carrera S. It's a proven tire on that car. Performs great. Lots of grip in the dry, and pretty good in the wet, too. Obviously a summer tire and not made for winter or cold conditions. Very happy with the tires!

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 take my '15 911 Turbo to the track 4-5 times a year. I drive in the "advanced group" at these events. The 4Ss I purchase failed in 3 track events. The outside edges of the tires delaminated to the cord! Michelin would not honor their warranty, even though these tires are advertised for occasional use at the track.
