Nitrogen in tires is becoming a popular replacement for
standard compressed air. Nitrogen is all around us. It's in
the air we breathe which is 78% nitrogen, 21% oxygen and the rest is
small amounts of other gasses. Nitrogen has many advantages over oxygen / compressed air. With nitrogen tire inflation, improvements can be
seen in vehicle handling, fuel efficiency and tire life through better
tire pressure retention, improved fuel economy and cooler running tire
temperatures.
