Most are filled with plain old air made up of 78%nitrogen, 21% oxygen and 1% other inert gasses. These days many folks are using straight nitrogen because it isn't affected as much as straight air by temperature changes. This results in longer tire life and better gas mileage.

There's moisture in air. When you fill your tires with compressed air, the moisture goes in the tire too. Moisture then has potential to rust out the rim from the inside. They use other gas (nitrogen?) that doesn't have moisture. Usually garages will put green air valve caps on tires filled with gas.

Nitrogen gas is used (a machine is used to convert air into nitrogen gas). It improves tire wear & gas mileage by reducing tire temperature. Normal compressed air also contains moisture, which is not good for rubber let alone tires. For more information, please contact your local tire center or auto dealer.
