Why is Nitrogen better then plain old air?

Well, Nitrogen is a non-flammable dry gas that keeps your tires properly inflated longer than "plain old air." Oxygen leaks out of a tire 3 times faster than nitrogen.
-Proper tire pressure lessens rolling resistance and maximizes fuel efficiency
-proper tire inflation ensures the recommended "contact patch" of your tire is on the road.
-Nitrogen provides more reliable pressure for reduced blowout potential.
It's best to use nitrogen in your tires whenever possible, but if you run into a situation where you can't get it, no problem. Go ahead and "top off" your tires with air. When you get the chance, head back to the dealer who inflated your tires with nitrogen for a refill. With nitrogen in your tires, your driving experience will be better, safer and less expensive.
