The link in the library is a reasonable start but it ignores the reality of side to side unbalance. With trailers getting ever larger and many now having slideouts this unbalance can mean the tires on one side have more than 50% of the axle load on them.
A more complete reference of how to know the real tire loads can be found by using the worksheet on this page http://www.bridgestonetrucktires.com/us_eng/rv/index.asp which can be downloaded as a PDF.
There is a good brochure with info on Loading and underinflated tires , Weighing your vehicle, Determining your vehicle?s capacity, Tire usage and care, Repairs, Air: your most important asset, Protecting your asset, Dealing with duals, Measuring and maintaining psi, Checking the tire air pressure, Common terms, and How to get help.
