285/75/16s: Air Pressure Question

Hello. I have 285/75/16 tires on my 3rd gen.

Just wondering what the tire pressure should be? Tire says Max pressure is 80psi.

I am currently running 40psi. I run normal load with my little kids in the car occasionally.
Not a daily driver but when it is driven, its mostly normal driving on freeway and street.

Tires are knockoff Hankook all terrains.
Wheels are low pressure Cast Aluminum and not steel wheels.

Thanks in Advance!

Angelo
