They recommend using those charts unless you want to blindly run what the manufacturer says that is a CYA for them.
Do you seriously think vehicle manufactures don’t know about those charts and don’t use them as one of the criteria when selecting a tire and determining what pressures are optimum for that particular vehicle?
Look at the door of a newer RAM SRW they call for 80psi rear. No one in their right mind would run 80 unloaded. The dash goes crazy if you lower the air on a 2500. 3500's you can lower without the nanny screaming at you. Of course they know about the charts! They base their psi's on them. Some times!
On my DRW they are right on with 80/65psi for full axle ratings. 80 is correct loaded or unloaded. I use the charts to adjust the rears. I checked yesterday my front and rears both have 8/32" tread remaining. No rotation other than moving fronts side to side with same rotation.
