Not so. I've measured it and the correlation isn't direct.

We don't even have to measure... think of the extremes: a tire with 500 psi and a 500 lb load isn't going to have a one square inch contact patch and a tire with 1 psi isn't going to have 500 square inches on the ground. However, there isn't even a small "zone" where that air/weight/area notion works.
