PLEASE explain if it's ok to run those pressures fully loaded why it's not ok to use the weight/inflation chart to lower the pressures for proper ride, traction and tread wear???
Use the charts and the brain GOD has given us.

The regulations and tire industry agree that the recommended cold inflation pressures on the vehicle certification label are correct.
They describe underinflation as having a cold inflation pressure below what is recommended. They describe overinflation as having a cold inflation pressure above sidewall max. Everything in-between is optional.
The primary purpose for TRA load inflation charts is to SET recommended cold inflation pressures. Retailers rely on the load inflation charts to set inflation pressures for plus sized tires.
If a consumer is acting as a tire installer for OE tires, a load inflation chart is not needed as the correct inflation pressures are displayed on the vehicle certification label, tire & load placard and in the vehicle owner's manual.
Many consumers confuse FMVSS standards with FMCSA standards. They are not applicable with each other.
