Add 14.7psi to the pressure the tires must sustain when environment
around them is 0psi.

The cold and heat may have greater effect on the rubber though.


Looks like a convertible, so no need to worry about keeping the windows
rolled down.

I would have hoped he would have had a "closed" car with air vents
plugged up to see how long any pressure can be maintained in the car.

Clearly, that would be a very short time. Car windows aren't sealed
air-tight.
