actually regarding the fact that nitrogen is an inert gas(i
think? it’s been 5 years since i took chemistry), the main
advantage is not that your tyre will not explode. honestly, that
probably hardly happens with normal air. the point is that the
amount of air expansion, and resulting increase in air pressure, in
the tyre when it warms up due to friction while vehicle is moving,
while not sufficient to blow a tyre up, its sufficient to affect
the contact patch of the tyre. hence your car’s handling and tyre
wear might vary according to tyre temps. this is a very impt factor
esp when racing applications are considered, which is why racing
teams tend to use nitrogen in their tyres.
