That makes total sense, again - thank you!

Awesome - I’ve always loved Chem/Phsysics, so now that I know there is a formula for this, I am satisfied :) thank you for providing this!

I had not heard of/considered “absolute” pressure before - not my area of expertise - so that definitely helps me better understand this. Thank you!

Had another thought after rereading your last statement about water…

Would this mean that going from an extremely humid climate to an extremely dry climate would also impact the tire pressure? Just less significantly than a change in temperature?

Just curious if there is some mathematical equations that would represent the multiple factors you’ve laid out to explain the impact on the tires psi.

You’ve pretty much answered my initial question, just the math nerd in me wondering if this is a thing, so had to ask lol.

Very good explanation…thank you!

Ahh okay. So they don’t just slow down and give less pressure - they actually condense into water, and give no pressure at all then?

I don’t think I ever would’ve thought of them turning to water.

Follow up - if you’re interested - how does this affect the pressure of the tire if you fill it up in the winter, and then it gets warmer out? Wouldn’t that make the psi too high?
