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.

Since nitrogen does not completely eliminate temperature-related pressure changes under normal driving conditions, it is of little benefit to vehicle owners who properly maintain their tires.

Fact: The opposite is true. Even tires filled with nitrogen still require regular pressure checks to identify slow leaks. It is also a good practice to visually inspect tires for cuts, tears, bulges and tread wear, or other signs of impending tire trouble.
