This may be good info for a little car tire with max 32psi or whatever rating, but it is NOT a 1 size fits all is correct recommendation. Period. Grossly over inflated ties ( for the load, even if within max sidewall psi) can be almost as dangerous as under inflated tires in some (maybe different) situations.
Also remember that car tires are over inflated by default to up the gas mileage to meet CAFE requirements. The door sticker amounts to government propaganda and should be viewed with that in mind.
