Tire pressures--newbie questions!
I recently purchased my first RV (1998 Coachmen Catalina 22RK, Ford E350) and immediately replaced the 10 year old tires with new ones (Aeolus CrossAce HT AS02 LT225/75/R16). I've done a lot of read...

BUT!!! Capri is a Tire Professional!
And Michelin needs no introduction anywhere on the planet. That's why their "RV" pressure chart is by CORNER. They've learned that RV's tend to be loaded more unevenly than Trucks on the same chassis. So they try to encourage us to consider corners as Capri says. My belief is that you will not be THAT far off. The offenders, oddly, seem to be the left front corners of Diesel Pushers. They put a huge slide on the driver side and the generator's forward of the front axle.
Anyhow, I think going 5-psi over charted pressure will give you a factor for imbalance.
Capri, OP has weighed coach in its fully loaded state, people and all. Yes the chassis could carry more but they about can't do it. Unless they buy sacks of fruit to haul home from vacation or something... Would you mind taking a moment to run "reserve capacity" on the OP's numbers? It seems to me that the calculation would result in pressure for either GAWR or Tire Sidewall, both of which seem too high for the actual load.
And this I CAN say even as a non-tire-professional: Cannot run excessive FRONT tire pressure on a Ford chassis or the thing Will wander.
