The vehicle manufacturers tire placard is a recommendation only. They have no idea how much weight the truck owner will carry on the trucks front or rear axle.
Hell my 2500 Dodge/Cummins came with a 50 psi for the the front and 75 psi for the rear on LT265/70-17 E tires.
The front tires at 50 psi were rolling on the edges empty or loaded. I use the chalk line method and found 65 psi worked best. I found 45 psi works best when the truck is empty and 70-75 psi when carrying a load.
Thats why the tire placard says see your owners manual.
Owners manual says to adjust the tires pressure according to the load carried or accordingly.
I have a 1500 4x4 truck and a older one ton DRW 4x4 truck and they all require different tire pressures that are different than their tire placard pressure recommendations.
IMO the tire placard is a good place to start. Then fine tune them from there. I generally run my LT tires up to 115k miles on 3/4 ton trucks. DRW trucks around 75-80k and 60-65k on the 1500 trucks by using the chalk line method when empty and carrying a load.
Learn to read your tires and of course having a large air compressor at home to quickly air up helps.
