Proper Tire Presure
What should the proper tire pressure be on ST205/75R15 tires on a travel trailer? Thanks

I have yet to see a trailer with recommended pressure on a sticker, but every trailer tells you max pressure at max load.
Tire manufacturers publish load/inflation charts for a reason, proper pressure is the pressure at which the tire can support the load applied.
Overinflated isn't as bad as underinflated but still has drawbacks such as decreased traction, decreased tread life, increased susceptibility to road hazards, and transfer more road imperfections to the trailer.
The correct answer to weigh your axles and adjust accordingly. 5 psi over chart pressure is also recommended, up to sidewall max, if you will be driving 60-65 for a long ways. Until you can weigh your trailer run max pressure, but do weigh it.
So far on my new 16 MobileSuites I have not seen anything about air pressure. The rig did arrive with 115psi in all 4 tires. After I weigh each wheel I may end up lowering to 110. The tires are GY "H" with a max pressure of 125psi.
But the fact is "MOST" RV's should run MAX pressure because they have these RV's maxed out based on the carrying capacity of the POS tires they install.
