There is plenty of nitrogen in the air that surrounds us, and more than likely in the air pumps that you would normally use. Nitrogen in a pure form is less susceptible to a sudden drop in temperature. The other day here in Central Virginia it was 69 degrees during the day and the temp had dropped to 30 degrees by the next morning, my TPMS light did not come on. Under normal conditions when I had air in my tires a sudden drop like that would have set off the TPMS.
