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.

This, I use this table. It's also published in your e-manual. For my trips, I typically go with 5-seater full load (most trips are packed vehicle). Hot tire pressure does get uncomfortably high in hot climates, and I tend to adjust down to the halfway point between partial load and full load.

Monitor your pressure in hot climates and ensure it's not approaching tire's max pressure limit published on the sidewall
