Have GMP substitute Nitrogen for O2 in each wheel when mounting a new wheel and tire package.

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 percent of the air we breathe and traditionally fill tires with. N2 is a larger molecule than O2. Therefore, it cannot escape as easily as oxygen through porous material such as a rubber tire wall (carcass). Leaking at a much slower rate than oxygen, a tire filled with a higher percentage of N2 maintains its proper pressure roughly three 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 and Tire Pressure Monitoring Sensors.

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. N2 has been used in tires for many years on aircraft, military vehicles, off road trucks, racecars and even Tour de France bicycles.
