Are you sure you are not carrying some gold bars for an emergency. They are very heavy.

You definitely never want to run lower pressures than the name plate. As the others have said run it across the scale. You need to run both sides of the axle at the same pressure necessary to match your actual loads.

Many tire sidewalls are ruined by running them to low. In my experience running the tire side wall value has worked fine although many folks like to have the tire cushion the ride a bit. I like it a bit firmer and don't like the squirm you get running them lower.

Bottom line is if they run hot then you are either under inflated or over loaded and if you are at 130 already then hopefully they are not running hot.

Be sure to let us know what you come up with after weighing the axles
