I only brought up axle rating as max air pressure is 1760 lbs over axle rating per axle. 100 psi will be 4080 lbs per tire.
I'm at 15,500 lbs on my axles.

"WE" understand that but some may not is why I mentioned it.

My axle ratings are 8k each but my combined load is 17,500#. I am actually within the IS specs at that weight.

Your minimum tire inflation pressure is displayed on the vehicle certification label. NHTSA and USTMA both agree that the vehicle manufacturer's recommended inflation pressures should NEVER be reduced below what is recommended for them on that vehicle.

Inflation to the load carried is not an approved method for tires installed under the guidance of FMVSS.

Inflation pressures for the load carried comes from the truckers regulations (FMCSA) and are not applicable for RV trailers.

Someone referenced a GY inflation recommendation. They may not have read to the bottom line; here it is:

"Tire pressure should never be reduced below the vehicle manufacturer's recommended levels to support load conditions in order to improve the ride quality of a vehicle. The difference in ride quality is not significant. When minimum inflation pressure requirements are not met, tire durability and optimum operation can be affected."

The vehicle manufacturer's tire inflation recommendations are the minimum inflation requirement.
