Changed out my rims with 22" rims with 285 35 22 tires and aftermarket tpms. What settings are you guys running in menu options?
I selected summer tires, 21 inch, full load. Can you guys tell me if this is the appropriate settings?
I have aftermarket tpms and they read after reset and driven on, except now I still have a tire warning of a flat. Should I add more air? What psi to fix this error because ot is saying -15psi in tires.

Right now tires are filled at around 36psi. I dont want to add 15 psi because that would make tires at 50 psi and I believe that is over inflation of recommendation on tire. Tires are yokohama parada 285 35 22.

I have 22's with P Zero tires on the Turbo. The highest setting is 21" summer tires, it came new from the dealer this way so I assume it is correct? They keep it at 42 psi in front and 48 psi in the rear tires.

Isn't 48psi pushing it close to max recommended tire psi? For sure it exceeds 50psi when driving from rise of temperature. I assume yours is set at full load from the lower psi in front and higher in rear? I switched mine to partial load with 41 psi all around. Max psi recommended for my yokohama parada tires are 50 psi.

Unfortunately there's not a "correct" setting because Porsche doesn't recommend a 22" wheel. You'll just have to get some opinions from other people with 22" wheels and go with the one that makes you feel the best!

Sorry, it is 46 in the rear.
