I just added some air bags to my aging F150 and was wondering what the differences will be to my ride as I change air pressure? This year I also went from "D" to "E" rated tires on the truck and ...

Fyi: the firestone airbags are rated as 40lbs of weight capacity per psi. at 40psi you've stiffened your rear springs by 1600lbs. that is a lot. i run mine at 8 psi unloaded to support my topper and 18-20psi when towing.
f250s with E rated tires have specified 50 psi as a front pressure in the past with the rears set as required for the weight. not sure if they still do this now.
i would try all the tires at 50, the airbags at 20, and adjust the wdh so the front stays at normal ride height.

Absolutely spot on! This is exactly what I discovered, 25PSI in the bags was by far the best feel for me. By your math (and I didn't know the 40lbs per pound rule) 25PSI equates to 1,000lbs and my TW is right on 1K.
Thanks for the confirmation, sounds like we're all on the same page. :)
