Putting pure nitrogen in tires comes from the aerospace community which is the standard. Filling tires with nitrogen prevents the formation of moisture in the tire that can cause corrosion and subsequent failure of the wheel and (for aircraft) since there is no water in the tire then there is a lessened possibility of the formation of ice in the tire. On cars and bikes there is no real need to run nitrogen in our tires unless you have had a recurring corrosion problem.
