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.
Nitrogen's larger molecular size decreases the rate at which it escapes
through the rubber of the tire, keeping the tire properly inflated over a
longer time.
However, it's not all about the nitrogen, it's about reducing oxygen and moisture. Oxidation can damage the tire and it's components, as well as the wheel. During use, a tire heats up and the rate of oxidation increases. Compressed air also contains moisture which can increase oxidation and cause pressure fluctuations.
While nitrogen will help you maintain proper pressure, you should still check your tires on a regular basis and/or as recommended by the tire manufacturer.

Nitrogen FAQs
Q: Does Nitrogen affect the accuracy of the Audi Tire Pressure Monitoring System?
A: No! Nitrogen as an inflation gas has no affect on the TPMS sensors. The sensors will read compressed air and nitrogen the same. The Tire Pressure Warning light should not be on if your tires are properly inflated with nitrogen to the manufacturer's recommended pressure.
Q: What is the best process for adding Nitrogen to my tires
A: You may simply add nitrogen to a tire already filled with air. However, in order to reap the full benefits of nitrogen tire inflation, you need to achieve the desired level of nitrogen purity (GNI recommends 93.4% for passenger tires and 98% for truck tires) and remove any moisture in the tire. To do this it is necessary to first purge the tire of the existing air, down to 3psi, and then refill the tire with nitrogen. This purge/fill cycle may sometimes need to be repeated to achieve optimum results.
