Tire Pressure/Contact Area/Weight
If you inflate a tire to 50 psig. If the contact patch of the tire is 6" x 12" (74 inches square). Is the weight on the tire 3700#? :h

I also suspect that generalisation, mayby they determined the surface at zero pressure and forgot that this surface gets smaller when tire is stiffer at higher pressure.
But first assumed that we did not have to do the work of determining surface for this tire, because it was so neatly given at the bottom.
I expect the deflection give to be right and staying the same over the whole range for a sertain speed. At least i expect that being the goal of the tire makers.
To determine that surface you could use more then 2 sheets of paper.
2 for the sides , 2 for the front and back and again 4 wich you put a bit in the rounding on front and back.
Glue it to the flat underground ( asphalt or concrete) and drive away and measure the area within the sheets more accurate.
