Improperly inflated tires can cause exces-
sive heat buildup, resulting in blowouts.
CAUTION
Over or under inflated tires can cause exces-

Inspect tires with deep cuts or gouges.
Measure the tire pressure if a tire
appears improperly Inflated.
Check the inflation pressure with the tires
cold, and at the same outside (ambient)
temperature in which the machine will
operate. Use a Caterpillar Part Number
9S6524 or 1P545 Tire Pressure Guage,
or equivalent.
Caterpillar recommends using dry nitrogen
(N) gas for both tire inflation, and tire

valve.
In addition to reducing the risk of an
explosion, using nitrogen instead of air to
inflate tires lessens the slow oxidation of
the rubber and the accompanying gradual
tire deterioration. This is especially
important for tires that have an expected
long service life (4 or more years) It also
reduces the corrosion of rim components
and the resultant disassembly problems.
Visually inspect the tires for cuts and
gouges, and for proper inflation.
