Hey ...why not fill your tires with Helium? they you could lift off the ground........lol

Sorry CRASH1369 not aimed at you.....
get your facts straight. there's no fake science in this thread. if you actually bothered to google, as i just did, you will see that nitrogen molecules are in fact larger than normal oxygen molecules. pure nitrogen inflated tires will leak less and are less susceptible to temperature/psi variations as well as being lighter than your typical air (4% lighter, however fuel savings are negligible at best). while our air is 78% nitrogen anyway, the rest of the gases you fill into your tires will find their way out faster, hence why pure nitrogen is used more commonly today.
