Proper PSI For Trailer Tires?
I'm curious as to what you consider the correct psi, to put into your trailer tires? I have a toy hauler, 28' twin axle. Fully loaded i'm 15 - 16K lbs. The max rating on the tires, is stated at 80psi....

The OP question was about trailer application. Most have the correct answer of using the pressure molded on the tire sidewall that is associated with the max load.
Because of the unique suspension i.e. when turning any curve or corner the tires do not rotate around a center-line that points to the center of the turn radius. This results in what is known as a "slip angle". This means that the "Interply Shear" force (the force that is trying to tear the belts of the body) I provided a link to the Google search results for "Interply Shear tires" for those interested in the technical details.
Motorhomes and other motorized vehicles do not have the same level of Interply Shear so they can inflate based on measured load, but I strongly suggest a cushion of +10% on the inflation needed to support the load so you don't have to chase your tail every day as ambient temperature changes.
