If you are one of 85% of Americans who don't regularly check tire pressure, you need nitrogen.

Air is composed of 1% water vapor and other gases (which escape 250 times faster than nitrogen), 21% oxygen (which escapes 3-4 times faster than nitrogen) and 78% nitrogen (which is the largest molecule in air, dry, and non-flammable)

Benefits of Nitrogen in your tires:
Increased Fuel Efficiency: correct tire pressure keeps the manufacturer's recommended "contact patch" on the road.
Longer Tire Life: oxidation caused by oxygen in air can make rubber brittle and cause it to lose tensile strength. 
Increased Safety: under-inflated tires is the cause of 90% of blowouts.
