We are giving you snippets of info, and if this is your first time with this issue, perhaps we have done a disservice.

So I'll start from the top. The manufacturers make tires in different sizes of course, but also within a size of tire, they also make different load ranges. If you go to one of the inflation tables for a specific model tire, you will find an array of sizes and load ranges. The tables are laid out so that for a given size tire and load range, they will tell you the maximum load on the tire for a given air pressure all the way up to the maximum air pressure.

Now take your axle weights. Use the heaviest weight per axle as your weight. You do not run unequal pressures from side to side, but you may run different pressures on the front and back. You use the table (size and load range) to determine the recommended inflation for the load you have.
