YouTube/Google chalk test
Gotta go off the tire inflation tables. Find the similar weight carrying spec for your OEM size, and then find that same weight carrying capacity for your new tire SIZE and LOAD RANGE.
That's the theory anyway.
Then, I usually go down a bit because the OEM PSI is meant for at capacity hauling, and I also ensure my rear PSI is 10% or so less than front when the bed is empty.
That's what I've done for about a decade now, because these E range tires on a half ton are so dang stiff that the chalk test for me has proven useless. I get the same results between 25-50 PSI.

i go 40psi on my 12-ply WIldpeak AT3. I'm supposed to do chalk test on it to find the optimal pressure but keep forgetting lol
40 is what we usually run in our group. some of our guys run 35 psi on lighter vehicles but that's just derived conclusion from our experiences. Nothing scientific about it.
OP do chalk test. start at 40 and go from there.
