Have to know more about truck and trailer before I can give an advice.
And those are ; from truck and trailer , best weighed tire-loads , second best weighed axle loads, otherwise we have to with GAWR's and GVWR , empty weight .
Also need maximum speed you wont go over for a minute.
From tires and so seperate for truck and trailer.
maximum load or loadindex, speedcode or ST, kind of tire to determine the AT-pressure.
But for the moment a guess.
Your truck tires are probably aftermarket with that E-load, AT-pressure 80 psi.
OEM tires are probably even P-tires with AT-pressure of 35 psi.
This makes me think you can even use a pressure of about 40 psi.
And then save for the tires up to maximum speed even.
Trailer tires are probably ST so calculated in their maximum load for more deflection allowed. So when I have the data, it might come out that you can even use 60 psi ( 10 psi above AT-pressure) to give maximum reserve.
