On my F350, there is no "airing the rear tires down". The placard calls for 80psi all the time. But I don't mind the ride. I only notice how stiff it is when I'm on a really bad road or when I'm going over a speed bump. I would not hesitate to use it as my daily driver.
Then that's your choice, the tire manufacturer would tell you that you are overinflated running 80 psi empty and are more prone to road hazard tire failures.
Are you sure there isn't a second sticker? Maybe on a different part of the door?
It's not a choice, and you're guessing what the tire mfg will say based on your lack of information. There is only one placard. 65PSI front, 80PSI rear. That is also what the dealer sets it to when he does the service on it.
Those pressures are a great recipe for outer edge wear on fronts and center wear on rears when unloaded.
