The PSI rating of the wheel is indicated by a sticker on the inside of the wheel. IIRC, the stock wheels on my Jayco Eagle were rated at 65 PSI. Have you checked this on your wheel? This very may well answer your question.
Additionally, I remember one of the major tire manufacturers published a chart with the weight rating of a particular tire at different PSI's. Weigh the trailer by axle, divide by 2, add a 15% margin of error, and the chart should give you a PSI. Too much air can make the trailer ride so harshly it could damage it.
I've got 2 Goodyear LT tires (Cargo, I think) that fit a Sprinter van on my front axle. 2 for the rear go on next year.
