If you put 35 PSI in a tire off the car, then put the tire/wheel on the car, the PSI of the tire remains the same, the contact patch changes from say a loading of 35 pounds of the weight of the wheel/tire and 1 sq. inch of contact to 20 sq. inches with a 700 pound load.
Thanks Hugh, that makes more sense...
