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

The picture of the footprints from capri-racers article give that much more pressure on the ground at the given pressures, that you can explain it by the overall surface minus groves and the sidewals press a bit more to the ground.
Even at the 16 psi most of contact is about 20 psi but even at the edges at the sidewals some spots up to 90 psi.
I also have a pressure loadapacity list from Michelin wich has 3550 kg at 6 bar with 777cm2 contact surface given .
this thoug would mean when supposing bar to be the same as kg/cm2, wich it is almost.
3550/6= 591 cm2 so this would imply that my theory of a part of the load being bare by the construction of tire to be wrong.
But how accurate is this given?
But if you would put the tire on a blunt nailbed it would give the same bending so total surface included the grooves .
