Would it be proper to deflate my tires in a linear fashion to match the weight on them?
The way I set my tire pressures is to weigh my rig fully loaded, add a little for safety factor and then use the tire pressure charts from the manufacturer.
I have a chart I made up for reference. As you can see, the relationship is not exactly linear, but not that far off. Assuming a linear relationship would not put your calculations off by much and would tend to over estimate the pressure by a small amount. Of course, different manufacturers will have different charts, but I am betting they don't differ by that much.
