TIRES

Handling Tires

If tires are not used under the specified conditions,
they may overheat and burst, or be cut and burst by
sharp stones on rough road surfaces. This may lead
to serious injury or damage.
To maintain tire safety, always use the specified tires.
Inflate the tires to the specified pressure. An
abnormal level of heat is generated when the inflation
pressure is too low.
The tire inflation pressure and permissible speeds
are general values. The actual values may differ
depending on the type of tire and the condition under
which they are used. For details, please consult the
tire manufacturer.
When tires become hot, a flammable gas is produced
and may ignite. It is particularly dangerous if the tires
become overheated while the tires are pressurized. If
the gas generated inside the tire ignites, the internal
pressure will suddenly rise and the tire will explode,
resulting in danger to personnel in the area.
Explosions differ from punctures or tire bursts
because the destructive force is extremely large.
Therefore, the following operations are strictly
prohibited when the tire is pressurized:
• Welding the rim
• Welding near the wheel or tire
• Smoking or creating open flames
If the proper procedure for performing maintenance
or replacement of the wheel or tire is not used, the
wheel or tire may burst and cause serious injury or
damage. When performing such maintenance,
consult your authorized regional Komatsu distributor
or the tire manufacturer.

Storing Tires After Removal

• As a basic rule, store the tires in a warehouse in
which unauthorized persons cannot enter. If the
tires are stored outside, always erect a fence
around the tires and put up "No Entry" signs and
other warning signs that even young children can
understand.
• Stand the tire on level ground and block it
securely so that it cannot roll or fall over.
• If the tire falls over, flee the area quickly. The tires
for dump trucks are extremely heavy. Never
attempt to hold or support the tire. Attempting to
hold or support a tire may lead to serious injury.
