after researching this (I was chastised and he was right) nitrogen will do nothing. I also suspect this started because someone saw a race team using nitrogen in their tires and jumped to the conclusion that it was a tip/trick. The truth is they use nitrogen for their air power tools so its very handy to air up the tires also.
