ABSTRACT:
A tire inflation apparatus and method involves first evacuating a seated pneumatic tire using a vacuum pump and then inflating the tire with a dried inert gas under pressure without allowing any ambient air to reenter the evacuated tire. The apparatus includes a three way valve which is connected by a first conduit to a tank of pressurized inert gas and by a second conduit to the vacuum pump. A hose having a tire valve chuck connected to a distal end is connected at the opposite end from the chuck to the three way valve. The three way valve selectively and alternatively flow connects the hose to the tank of pressurized gas or the vacuum pump through the first or second conduits respectively. The hose is initially connected to the vacuum pump to evacuate the tire, and then to the tank of pressurized gas to inflate the tire. A heater on the first conduit heats the cooled gas exiting the tank to raise the temperature of the pressurized gas delivered to the tire at least to the ambient temperature.
