I usta have the Ford shops adjust down my F250s. Idk what you'd adjust on a 350 though, since they are just an information system with no low pressure threshold?
That said, I agree with low rear tire pressures running empty.
But about 5 years ago, something changed and dealers can't /won't adjust them anymore.
I know definitively, FCA's diagnostic software removed the ability to adjust. Only means now I'ma ware of is aftermarket programmers/diagnostics like Autel.
