Two choices, IMO.

One, run max sidewall cold pressure at all times.

Two, go to the truck stop and weigh your boat and trailer fully loaded with a full fuel tank adding 200 pounds per person then add 10% for a safety factor. Check the tire manufacturers specs for the proper pressure for the load to be carried.

I believe choice one to be the low risk choice especially if you live where pavement temperatures are high and you tow at highway speeds. That's the choice I've been using for 38 years and I have never had a trailer tire failure or flat. Plus it's the easier choice.
