Just for the record, a close approximation of the tires foot prind loading of an air filled pneumatic tire is teh inflation pressure of the tires.
Secondly, theoretically and something to think about, a 125 lb woman wearing a pair of 7" spiked heel pumps can exceed the maximum floor loading of most buildings or run ways at a gentlemens clubs. Those heels have less than 1/2" square area of contact surface. So don't ever put your hand on the run way to pick up that dollar bill you just dropped.
