I have made it quite clear in my blog. Motorhomes can adjust their inflation based on the actual measured load but multi-axle trailers should run the pressure associated with the tire max load.
This is not the same as considering you are throwing money away.


InterplyShear is the primary cause of belt separations in trailer application and you should run the higher pressure than what is needed to support the trailer load as this will lower, but not eliminate the Interply Shear in your tires.


Sometimes Finite Eliment analysis is not something that can be equated to gut feel.
