You don't state the load range of any of your tires. 205 75R14 LRC tires are rated at 1760 lbs@50PSI and 205 75R14 LRD are rated at 2040 lbs@65PSI.

Depending on the tires on your trailer, if they are LRC, some of them are over-inflated and if they are LRD, some of them are "critically under-inflated".

Your trailer was built around the time that RVIA's new standards for tires was incorproated. So, depending on the weight of your trailer and the tires installed, you could be "relatively safe with some reserve capacity" or you could be "at the bare minimum capacity and any reduction in pressure could make you vulnerable to being overloaded on your tire capacity"...

You need a "real world weight" on your trailer axles to determine how much weight you are "really carrying on those tires" so you can make some sound decisions on what tires are required to support "YOUR TRAILER WEIGHT", not the weights in some chart or in some old brochure found on the internet.....

At this point, you need 5 new tires from a quality manufacturer, that adequately support your trailer weight. The size of those tires should come from an actual weight of the trailer and confirmed accurate based on the GVWR/tire requirements decals that are located on the front roadside corner of your trailer. Since your trailer is "previously owned" (I believe) then I'd want to verify the weight rather than leave it to chance that a previous owner might have added things that significantly change the weight of the trailer when it left the factory.....
