What size and load range are they?
My brand new triple axle hertiage trailer came with 235/85R16 Goodyear G614's load range G. They can be inflated to 110 psi. However, my sticker on the trailer says 245/75R16 at 80PSI to carry the load. Every time I look at it I think the same thing that is a lawsuit waiting to happen. With the 235/85R16's I actually need 90psi to carry the load. I haven't taken the wheels apart but I am guessing they are only rated to 80PSI like most of the wheels too. Hard for me to understand that they can be that clueless about proper ratings.

Max tire psi listed on tire trumps everything else.
I agree. Either a different tire is on the trailer than the trailer should have, or the trailer co fu*cked up and put wrong decal info on.
Never, ever, ever put more air psi in a tire than its max value primted on the tire says. You never want a tire (they are made of rubber and steel and other compounds) blowing out into your ribs or face. Bad !!!!!

Sometimes it's ok... Goodyear published this Service bulletin recommending 10psi over max on marathons. Like others have stated, run max sidewall pressure, unless you have the tires listed in the link below, then add 10psi.

Slightly related question. When your 3/4 truck is not loaded/ towing can you run lower pressures just to improve the ride?

I prefer 45-50psi. You may like something different. Over 50psi I can't stand the ride....which a lot of it is dirt roads and broken pavement. Oh, winter traction suks with a lot of air pressure.
