Ideal tire pressure for long trip

[Midzmerchant]

Hi fellow taycanians!

I am going on a long road trip of 650 miles. I just had my tires replaced recently.
I wanted to check what would be the ideal tire pressure for my 23 taycan GTS with 21 inch wheels. The sticker says 41 front 45 rear but I am not sure if there should be an adjustment if I have car with moderate stuff I’m carrying and if the pressures should be a little lower to prevent overheat and further issues with wheels especially I’m going 80-85 for long periods of time. Let me know please. Thanks

I just split the difference between loaded and unloaded as a happy medium for all occasions: 39 front, 41 back.

Lower pressures are worse if loaded and going at higher speed.
I run my 21" tyres at the loaded recommended pressure for long runs.

Use the TSB not the door frame sticker. https://static.nhtsa.gov/odi/tsbs/2026/MC-11027133-0001.pdf
TSB info ought to be in PCM as well.
