How Nitrogen Works and What It Does

Nitrogen (N2) makes up the majority of the air that we breathe and is contained in the protein of all life on earth.

It is colorless, tasteless, and non-toxic.

The next most common component of air is oxygen (O2).

Together, N2 and O2 make up approximately 99% of the air we breathe.

N2 is a larger molecule than O2.

Therefore, it cannot escape as easily as oxygen through porous material such as a rubber tire wall.

Leaking at a much slower rate than oxygen, a tire fill with a higher percentage of N2 maintains its proper pressure roughly three to four times longer than air-filled tires.

Proper inflation provides better fuel economy, superior handling, longer tire life, and increased safety by reducing the likelihood of low pressure related loss of control, blowouts and other tire failures.

N2 is a dry, inert gas.

O2 in a tire provides unwanted oxidation.

Over time, this reaction destroys the tire carcass and corrodes wheels.

A tire is prematurely aged by O2 from the inside-out as the pressurized air in the tire makes the O2 try to escape through the tire carcass, speeding up the damaging oxidation process.

N2 on the other hand, is a harmless inert gas that does not react negatively with tires and wheels.

N2 filled tires also reduce tire heat, thereby decreasing rolling resistance and increasing fuel economy.

N2 is non-flammable.

O2 is a flammable gas while N2 is an extinguishing gas.

Thus, a large number of mass transportation companies around the world fill their tires with N2 for added fire and explosion safety.

In a vehicle fire, ruptured air-filled tires fuel the fire. N2 filled tires slow the fire.

Nitrogen inflated tires are safer and longer lasting than tires inflated with air:

  • Nitrogen inflated tires do not age as quickly as air inflated tires.
  • Nitrogen inflated tires minimize blowouts.
  • Nitrogen inflated tires improve vehicle handling through proper inflation and consistently maintained pressure.
  • Nitrogen in an inert, non-combustible and non-flammable gas.
  • Nitrogen is a stable gas providing more constant pressure.
  • Nitrogen is a dry gas with no corrosive properties as found in compressed air.
