It might sound like a stupid question and the answer will most likely be something like this. "umm air 
"
But ive heard that some people componys and places use nitrogen(or some gas like that) in there tires instead because it doesnt heat up as much and it keeps the tyres at lower temps and it helps with tirewear.
Has anyone or does anyone know much about this or use it?
