Yes, certainly, but the issue for the OP was “how do I make the idiot blinky-flashy light go away if I set my tire pressure to 29F/31R psi”, and the answer for that is to go and set “comfort load, partial pressure” in your car, which is consistent with all of the manuals that I have been able to examine (my MY 2017 printed manual, and the online manuals for MY 2017 - 2019).

Has anyone gotten a warning when running comfort pressure going over 100mph. This happened to me in my 18 Panamera

Nope, I've gone up to around 150 on 'comfort pressure' and received no such warning.

Crazy. I must have a super early book, or a misprint. Spine of it says WKD 991 08 21 17, and the first page says 14/16 next to that same number.

Haven't found any online manuals for 2017-2019, at least in the PDF flavours.

I just downloaded and checked this for MY 2017 - 2019, and it’s consistent throughout, so there’s really no inconsistency at all between the online manual and the printed manual for MY 2017 through 2019.
i know I was, just wanted to add to the confusion.
the message is, keep tires within min and max based on personal preference and if car is loaded and if you wanted the lowest pressure, settings must be in Comfort and partial pressure to avoid the light warning

You have a unicorn!! Here’s my spine. And the inside page says 14/16 next to that same number.

I’ll bet that in 20 years it’ll be worth a bajillion dollars!

Regarding the PDFs - I used the Porsche “good to know” app and downloaded the manuals from there - not PDF per se, but about as close as you can get.

yeah I'm at a complete loss. same numbering and all that, early MY2017 car, but super different manual. your chart is all on one page, mine's split up between two pages, AND has different information.

How do you define partial loaded vs fully loaded? I assume partial = 1-2 passengers vs fully = 3-4 passengers? Curious because throughout the week i vary between partial & full loads. So I'm trying to figure out what to go with for pressure setting to be on the safest side so that I'm not having to constantly change the pressures.

According to this article, it’s .... running with full fuel, the full 660 pounds of cargo/passengers AT TOP SPEED.

Nothing wrong with setting Comfort Partial Load in multi function display and set pressures a couple lbs higher than recommended all around.

According to my owner's manual for a 2018 C4S, comfort pressure, partial load for summer tires is 29/33 psi f/r with a top speed of 165 mph. Winters tires on 19s are recommended to be set at 31/33 psi. Works well for me for my summer Michelins and winter Continentals. Car has minimal rattles even on rough roads and the ride is smooth and comfortable.
