Those are excellent tires for trailers grossing up to about 10,000 pounds.

But trailer manufactirers tend to install tires that are barely adequate for the GVWR of the trailer. I would weigh the wet and loaded trailer, and if the weight on the trailer axles is more than about 10,000 pounds, I would seriously consider replacing the tires with LT235/85R16E before any long trip.
Your tires are LT and not ST, but that's okay because they are real truck tires rated for "all position", including trailer position. All-position tires cost more than simple pickup tires, but they are available. If you prefer the Goodyear brand, then go with the G614RST in size LT235/85R16G:

If you don't want to mess with new wheels, you could go with Michelin XPS Rib in size LT235/85R16E, which will work fine on your 6" rims. They have 3,042 weight capacity @ 80 PSI.
As to "hot" tire pressure, don't worry about it. As the others have mentioned, be sure you have at least 75 PSI cold pressure, then hit the highway and don't worry about PSI.
