The vast quantity of different molecules that make up "Air" are often very small, so small that they are actually able to seep through the RUBBER of a tire over time. This is why racing and many wheel shops have gone to nitrogen to fill their tires. It's a larger molecule that is less reactive to hot and cold, so pretty much whatever pressure you set it at cold, that's what it will be hot, and it won't seep through the RUBBER.

yes it does the seal around the bead isnt 100% and slowly a little air will leak out not going through the metal but seeping out at the low quality bead where the tire meets the metal and this will happen if the bead isnt cleaned everytime u get new tires and ull lose more air through this then the air seeping through rubber that is usually up to half an inch thick

and air is only made up of 2 molecules that make up 99% of the air - 78% nitrogen and 21% oxygen with another molecule argon which is <.1% so maybe if u lost all the oxygen in ur tire you would still have 78% of an inflated tire with pure nitrogen so getting ur tires filled with pure nitrogen seems a little overboard

and you should be taking the class and ill continue to get high

1% Water Vapor and Other Gases – Escapes up to 250 times faster than Nitrogen
21% Oxygen – Escapes 3-4 times faster than Nitrogen
78% Nitrogen – The largest molecule in air

Class dismissed
