This is bad advice. Your tires will get hot anyway while you're driving. Following the above procedure, your tires will be over inflated in real world driving. I know a lot of people around here like to overinflate anyway but you at least want to have an accurate idea of the pressure in your tires when the car is moving.

If you are over inflating your tires, always check the pressure right after driving on the highway. This will tell you the peak pressure in your tires.
