Inflating to max load will cover anything you put in it but loading to the max sidewall pressure when not needed will result in a lot of bouncing being that most trailers do not have shocks to stop that.
Inflating to max trailer load if your anywhere near that actual load (from what I've seen, many are at or even above that load given the marginal load capacity of trailers) gives you ZERO margin on tire capacity. Loose a few psi over time and your overloaded.
And don't assume that tire load = (GVW/4)!!! If your going to go on actual tire load, you need to determine ACTUAL load on each tire, which means getting weights on each tire individually.
Better to inflate to cover some % over actual max load, just like cars and trucks do.
