I recently saw questions about tire pressure for the track and was curious what people are running for the street? I have Cup 2 tires. When I was looking it was interesting the door jam did not match what is in the manual. They are pretty close, but different. Door 32/35 Manual 31/34.
TPMS display seems to be a few pounds higher compared to when I use my pressure gauge (I verified with 2 gauges). The MyPorsche app is +2 +3 lbs higher than the actual pressure.

Look at manual and see the Performance tire pressures (I think somewhere around 27psi front and 30 psi rear when cold). The variations you see on the door jamb and manual has to do with incorrect conversions from Bar to PSI…
The Performance pressures give better handling and ride quality, but should not be used over 290kph (around 180mph).
When I use a good separate digital pressure gauge, it shows 2psi higher than what the dashboard says…
New owner and I recently adjusted from whatever high pressure the dealer set the car at, to 28/31 based on the advice of the forum. It’s as described; a night and day difference.

And just a reminder that you may want to corroborate the dash readings with a separate digital tire gauge, as the dash seems to intentionally underestimate the pressure by a couple pounds (to make you fill more often or something).

absolutely, I set to my motion pro gauge, and completely disregarded what the dash said. 🥂
