Air craft use nitrogen because its dry and they cant have water vapor freezing inside the tire when its -40'F and for fire safty.
Same thing with nascar, but fire safty only.
Years ago they used air.

On a side note, I read that Lexus rolled cars to the dealerships with tires filled with argon. Reason for doing this?
To further dampen road noise. (it seems to work in between window glass panes)
I may test this one out, get my girlfriends Iphone and one of those free sound meter apps and do a before and after test. All I have to do is devise a way to get the argon from my welding bottle to the tire.
