Ideal tire pressure

[vks]

I have a MY23 4S. 8 months into ownership, loving it! No issues (fingers crossed), except a visit to the dealer to clear a battery sealant recall (campaign number APB2).

Question: What is the recommended tire pressure to shoot for? I have 20 inch turbo aero wheels. Current snapshot from My Porsche:

It's been updated a few times, now January 20, 2023 as far as I can tell. Porsche doesn't seem to keep the online manual up to date?

I've been running 37psi front and 34psi rear on my summer 20" and like that setup. Taycan 4S with usually just me in the car.

If these are original fit then the plate at the bottom of the b-pillar visible when you open the driver's door will have the factory settings.

Unfortunately, US cars just provide a single suggested pressure along the B pillar. In my case, it recommends 39psi front and rear which would be WAY too high for driving around by myself. Settings pressures according to the specific tires and loading in the owner manual made a huge difference in traction and road feel.

Use what the PCM tells you for your tire and wheel size as the starting point. FWIW I run exactly what the PCM says for my wheel and it’s the best combination of even wear and range.

Great, will check it out. Appreciate the tip.

Thanks, want to make sure I understand how to read the PCM info. As example, for the front left, it's showing 34.8 (-1.5). Does that mean I need to inflate to 36.3 psi? And similarly to 33.3 psi for rear tires where it's showing 37.7 (+4.4)?

Im talking about going into the settings where it asks you to select your wheel and tire and then tells you the recommended pressures. I’m assuming the display is showing you results based on that but would be good to check the proper tire and wheel is selected.
