Why is nitrogen better for tires?

The Nitrogen Advantage

Nitrogen molecules are larger and slower moving than those of compressed air. Because of this, nitrogen won’t seep out of your tires as quickly as air will, helping to maintain proper pressure for a longer period of time. The benefits of proper tire pressure are numerous.

Why would you put nitrogen in your tires?

Fact: Tires filled with nitrogen maintain inflation pressure longer than compressed air-filled tires in fluctuating temperatures. This is why nitrogen is used to fill airplane tires, as temperatures can change dramatically between takeoff and landing.
