If the tires have 1760 lb on them you should run 50 PSI, if less weight then you could run less PSI.
Over inflated tires will wear faster, have less traction for braking, and are more liable to cause trailer jackknifing. Obviously the ride suffers, and potential damage due to potholes increases.
If you tell us the ACTUAL weight on each wheel when fully loaded we can then tell you what psi would be recommended by many manufacturers.
For example I have a little single axle TT with ST205/75R15's on it. When fully loaded, as we use it, it weighs 1580#. The tongue weight is 200#, so assuming equal loading there is 690# on each tire. Normal DESIGNER recommended psi of 15 psi will handle a load of 905#.
Does anybody think I should really inflated to 50 psi? If I do so the trailer will jackknife in a heartbeat.
I actally run 20 psi, 15 is a bit too low for my comfort, but I'm sure not running 50 psi. It would be like running solid steel wheels with no tires. Ever ride in an old buckboard?
