Why nitrogen filled in tyres?

Nitrogen gas is an non flammable gas,it only catches fire when mix with oxygen or moisture as the tyres have absence of oxygen which help tyres to be roll down on the road with low temprature which help tyres to keep away from brusting off which can cause incident.

The principle of the temprature says that every 10 degree temprature will result in apporx. 1psi change in air pressure.

And it is also a low temp gas which is also called dry nitrogen which helps tyres to keep cool in summer season.

Thank you
