Does that seem low?

They are Goodyear marathon trailer tires and I was surprised to find such a low pressure rating

What kind of TT do you have and what is the trailer's recommended inflation (per tag or manual)?

The rating plate in the side of the trailer is sun faded but the trailer is an r-vision trail cruiser 30QBSS

According to a used-RV web site your trailer has a gross weight rating of about 6K lbs. It also lists the tires as 205/75R14. Goodyear Marathons in this size are load range C and the max inflation pressure is 50psi. Are you sure about the 35psi max? The tire rack doesn't even list a Goodyear Marathon in any size with max inflation pressure less than 50psi.

I'm sure, I walked around the rig and checked all four tires and the spare. All of them say maximum inflation pressure 35 PSI, all of them are Goodyear Marathon 14" tires, and all of them have two warnings on each side wall stating "Do not mount on 13.5 rims"

I'm going to check the date code tonight, I suspect that perhaps the tires are very old and I should just replace them anyway. My old TT had car tires, so switching to the newer TT with 35 PSI max seemed normal to me. My only concern was reading this post, I was shocked at all the posts listing 50, 60, and 65 PSI ratings... that is what made me suspicious of my tires.

You are bang-on about the GVWR of the trailer, that sticker is still inside on a cupboard door panel. I had to make sure of that one before purchase LOL.
