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 result is stronger casings.
Oxygen vs Nitrogen Comparison
Nitrogen
Compressed Air
Dry and Clean
Oily and wet
Remains stable at any temperature
Highly reactive element at high
temperatures/ pressures
Eliminates condensation which
prevents rim rust
Creates moisture in the rim leading
to rim rust
Slows migration to only 2psi loss
over 6 months
Fast migration, 2psi is lost each
month
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 unnecessary
costly service calls
