It is generally accepted that all gases obey the ideal gas law if you stay
away from their condensation temperature.
Not true. Unless you introduce nitrogen to the tire under ideal
conditions, which would entail a vacuum process first. Do you really
think that people are going to do that, when all they need is a larger
tire?
Air is mostly nitrogen, then
oxygen, carbon dioxide, and traces of many other gases including water.
Bingo, you're starting to get it. Water.
It's water VAPOR you moron, a gas. It obeys the gas laws until it
condenses or sublimates. Are you saying that's what happens inside a
hot tire?
Unless you have artificially introduced liquid water into the tire, or
inflated the tire with air super saturated with moisture, the typical
operating temperature of the tire will sufficienty above the dew point of
the air inside such that the air (complete with water vapor) will obey the
ideal gas law.
Again, unless introduced under ideal conditions, there WILL be water
vapor.
Proof you don't know the first thing about high school physics if you
think water vapor in air causes it not follow the gas laws. You do
realize tha if you put nitrogen in a tire, chances are you'll have some
water vapor in there also.
