Two valves are needed when filling tires with nitrogen. One is used to allow existing air in the tire to be expelled as nitrogen flows in from the other valve. Once expelled, the second valve is closed so that the tire is 100% filled with pure nitrogen. Nitrogen is used because it does not absorb water as does the air we breathe and this allows the balancing of the wheel & tire to remain unaffected by moisture content in the air.
