Nitrogen is an inert, dry, non-flammable gas that’s used by NASCAR racers, the aircraft industry, the U.S. military, Formula One racers, and others to inflate tires. So why do the tires on a truck or the family sedan have “plain old air” in them?
Well, it’s probably because the owners didn’t know about nitrogen and the benefits of using it instead of “plain old air.” And frankly, it hasn’t been readily available at local tire stores because there hasn’t been a way to produce or provide nitrogen to the average user.

	Nitrogen is all around us. The air we breathe is 78% nitrogen, 21% oxygen and the rest is small amounts of other gasses. When it comes to tires, oxygen is the culprit. Nitrogen in tires instead of “plain old air” maximizes the vehicle’s handling, fuel efficiency, and tire life through better tire pressure retention, improved fuel economy and cooler running tire temperatures.
Commercial users will enjoy the benefits of eliminating oxidation, improving retreadability, eliminating rim rust and the resulting strong casings.

Benefits of Nitrogen

• Better tire pressure retention – Nitrogen migrates through a tire 3 to 4 times slower than oxygen. It may take 6 months to lose 2 psi with nitrogen compared to less than a month with oxygen.
• Improved fuel economy – A result of having the proper air pressure which lessens the rolling resistance. Under-inflated tires have a greater rolling resistance.
• Cooler running tires – Tires inflated with nitrogen run cooler than tires inflated with regular air.
• Removal of oxidation – Oxygen is a highly reactive element at high temperatures and pressures. Replacing the oxygen with nitrogen helps eliminate the oxidation that damages inner liners and belt packages.
• Improved retreadability – Eliminating oxidation also improves the retreadability due to more flexibility in the tire casing. Less tire aging and tire cord rust could very well increase the number of retreadable casings and also increase the number of times a casing could be retreaded.
• Elimination of rim rust – Since nitrogen is completely dry, condensation is eliminated which eliminates rim rust.
• On-the-road reliability – Tire failures can be significantly reduced while reducing down time and costly service calls.
