Yes, the 4S are N rated.

 

Took delivery a month or so ago - car had been on the lot for a minute before that. Has P-Zeros. I have no issues with them so far. Two trips to the track (15-20 laps each day) and they are holding up nicely and performed well.

 

Thanks. Silly me, I should have carefully check the pics of OT. Fronts look like they have the lips. Now, at least I have a couple of OEM choices when changing tires next time

 

My GTS built 12/22/17 has the Michelins, but based on earlier responses it is still a lottery.

 

 

My 2018 C4S delivered in August 2017 came with Pzeros N1s. They are noisy as hell. Never realized how bad until I switched to Winter contis. Night and day difference in noise and winter tires are supposed to be noisier. In my previous Porsche, a 981 Boxster S, I noticed a substantial improvement in ride quality and noise when I dumped the Pzeros N0s for MPSS tires.
I will be dumping my Pzeros N1s for MP4S this spring. Yeah it is a loss but another 2k is not much in the grand scheme of things for a car that cost me 125k. I am not driving on the Pzeros anymore in my new 911.

 

I have the Yoko 19s and noisy.. Gonna get the MPS4S next

 

I swapped out Pilot Sport Cup 2's for PS4S (non-N Spec since those weren't even out at the time) last September shortly after buying my CPO 2014 991. The Sport Cup 2's were basically brand new (300 miles on them) but were squirrely as hell in rainy conditions. I've put 6,000 miles on my PS4S tires and have no complaints, and they handle excellently in the wet weather (in fact, it was pouring rain this morning on my way into work, lots of standing water on the roads, and it reminded me of what a great decision it was to switch out my tires).

 

I really-really liked the old Michelin PS2s. Since then, Michelin has made their tires less expensive, longer tread life, and better in the rain. But, really, those 3 improvements don't really benefit me. Maybe someday I should consider the Cup 2s, but I think that's too far the other direction (too $$$ and too little tread life). It's the Goldilocks conundrum.

 

October '17 build came with Michelins. The C2 GTS tire pressures as listed on the door jam (35/45) differ slightly from the manual (33/44). Tire pressures will rise as temp in tire goes up. I just set temps when tires are "cold" and leave it at that.

 

Note that the "door jamb" tire pressures are for high speed/high load use. Pressures for light load are in your owner's manual. My dealer told me they're required (by law? Lawyer's advice? Don't know) to always inflate tires to that HS/HL setting, purely for purposes of liability protection. If you're driving the car solo, with no luggage -as most of us drive our cars - they ride like hell with those pressures. Very harsh, noisy, and relatively poor handling. Take them down to "comfort level" or "low load" and it makes a world of difference, all for the better.

This advice is purely for driving on the street. Track use is a whole different matter. Running hard on a hot day, you'll et so much air out of your tires that you have to pump them back up before you can drive the car home!
