My Expy calls for 30 front / 35 rear. Yours is likely similar. This is to account for a loaded condition where you put all your crap (or attach a trailer) in the rear.
It is generally safe to run tires all the way to the max printed on the sidewall. MFRs often specify a specific pressure below this because ride quality suffers with high pressures. So the MFR recommendation is often a balance between load capacity and ride quality.
Interestingly, the weight distribution on my Expy is darn near 50/50 front to rear. This is generally considered ideal for a sports car. An F-150, in comparison, will have much less weight over the rear compared to the front.

There is a reason that manufacturers specify tire pressure. It's for safety. You seriously don't think that they have you lower the pressure below the max because it will line their pockets.
FWIW our '04 Navi's sticker says 35psi front and rear.

That is very bad advise Jordan not Mike....
Never run the max tire pressure....
What Ford has on the vehical stickers tire pressure are what is only good for the ORIGINAL tires on your vehical.
Once you buy a different set that goes out the window.
Run what your tire mfg recommends.
I have Bridgetone Revo AT's...I run 35psi all around...have even wear and good overall ride. In winter I go to 32 to 33.
