    Back in the 70's I was way out in the toolies and had a tire get punctured. Narrow road and a snow berm on both sides. Did not want to change the tire in the dark under those conditions. Thought about the pressure chart for R12 and at the temperature that day I think saturation was about 32 PSI so I dumped a bit of R12 into that tire and drove it back to town hissing all the way, but maintaining the pressure in the tire as the liquid vaporized. Back then, R12 was in the 50 cents a pound range....

    Do not recommend using liquid R-anything in warm weather!

    Hows that? Doesn't the spring (and the pressure in the tire) hold it shut? Any pressure from outside would act to open it, once the pin has been depressed. Right?

    It certainly wouldn't want to open if the tire pressure was greater than the hose pressure. But then, if that were the case, you wouldn't be getting anywhere trying to air it up anyway.
