ABSTRACT:
A tire inflation apparatus and method involves first evacuating a seated pneumatic tire via a vacuum pump and then inflating the tire with a purified, dried gas under pressure, such as pressurized nitrogen, without allowing any ambient air to reenter the evacuated tire. The apparatus includes a three way valve which attaches to the source of compressed dry gas, to the tire valve, and to the vacuum pump with a micron vacuum gauge provided for monitoring the state of vacuum within the evacuated tire.
