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 .

Yea! A real world example. Thank you Gdetrailer! It sounds as if it would be reasonably accurate to determine the loading on each tire and could help with determining the load on the rear tires with and without the trailer attached or the actual weight of the trailer when it's not practical to get to a scale.

Not real life numbers. Just a mathematical example to test the hypothesis and start a discussion on a cold winter day. If true, could be a way of figuring weight on each tire, knowing the pressure and contact patch. I know of a high school science teacher that slipped sheets of paper under the front, rear and sides of a tire to enable measuring the tire contact patch to come up with the weight on the tire as stated. Force (weight) = pressure x area.

......and if that is the pressure inside your tire then 50 is also the average PSI on the contact patch.
