720 / 24 = 30 lbs per square inch.

One more thing that I did not mention.
Is the square area of the solid rubber sections of the tire face
against the driving surface. You calculated the square area of the
actual contact surfaces of the tire and divided that into the
vehicle weight that is on that tire.
The best way we did this when we were road rally racing, is to ink
the tire and than lower it on a white plastic cover board. You will
find that a wide tire will have a narrow foot print about 2 inches
long for the width of the tire. If there is no thread on the tire
and the tire is 12 inches wide, then you have about 24 square inches
of contact rubber.
Lets say the weight on that tire is 720 lbs, therefore 720/24 = 3
lbs per square inch which is not good for traction.
