Tire Inflation with Nitrogen
SMCS Code: 4203
Caterpillar recommends the use of dry nitrogen gas
for tire inflation and for tire pressure adjustments.
This includes all machines with rubber tires. Nitrogen
is an inert gas that will not aid combustion inside the
tire.
Proper nitrogen inflation equipment, and training
in using the equipment, are necessary to avoid
over inflation. A tire blowout or rim failure can result
from improper or misused equipment and personal
injury or death can occur.
A tire blowout and/or rim failure can occur if the in-
flation equipment is not used correctly, due to the
fact that a fully charged nitrogen cylinder's pressure
is approximately 15000 kPa (2200 psi).
There are other benefits to using nitrogen in addition
to reducing the risk of an explosion. The use of
nitrogen for tire inflation lessens the slow oxidation
of the rubber. Use of nitrogen also slows gradual tire
deterioration. This is especially important for tires
that are expected to have a long service life of at
least four years. Nitrogen reduces the corrosion of
rim components. Nitrogen also reduces problems
that result from disassembly.
A tire blowout or a rim failure can cause personal
injury.
Use a self-attaching inflation chuck and stand behind
the tread when inflating a tire, to prevent personal
injury.
