If you took measurements at each wheel while fully loaded you could use the table this way according to Goodyear. My approach was to use the D rated max inflation which was recommended by GDRV and apply this D rating to the E rated line on the chart. This would correlate to 50 psi at 2150lbs. I however wanted additional support without running the tires at their maximum sidewall pressure so I run my tires at 60 psi to give them an additional 230 lbs of support each while having the advantage of a heavy duty tire that will be more puncture resistant at the lower pressures.
For fuel economy, I have not noticed any significant difference while running the E rated tires on both my half ton truck as well as the Imagine. 9-11 mpg depending on terrain, wind direction and speed.
