How do you measure the tire area on the ground? Is it in square inches?
I park the trailer on a flat suface or pull the trailer onto a piece of 2x6. I take two pieces of white paper and slide them in on each side of the tire (the front and back) and measure the distance between pieces of paper to get the length of the tire track. I then repeat and measure the width of the tire patch.
Multiplying these two dimensions gives me the area of the tire in contact with the ground. I than measure the tire pressure and multiply it by the area. The product is the weight
on that wheel. I repeat the process for the other side.
I do roughly correct for the tread pattern, reducing the width by the width of the tread cuts.
I used to do this for our Motorhome and after doing it, scale weighted the motorhome and the results were very accurate.
Though some may question the precision, it is certainly accurate for measuring side to side differences in weight
We use a bathroom scale to measure tongue weight
Hope that was clear,
