Proper Pressure for Michelin PS4?

[4thPcar]

I have the MY 2022 base with 285/40R20's and am confused with by all the different sources. Car's label says 35F/38R. ChatGPT says 35F/33R. Guy at Discount Tire said all the Taycans he sees are requiring over 40! I know that Porsche puts out an online link with updated info on recommended tire pressure but I don't know how to find it.

Any help?

Look it up in the manual in PCM, and/or

That's the link I lost! Thank you And score one for ChatGPT. It was the only one to nail the right answer.

The manual generally says that the door label overrides anything in the manual. It has been created with reference to the specific options on your particular vehicle at manufacture.
