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 adhere to the follow-
ing conditions:
• Inflate the tires to the specified pressure.
Abnormal heat is generated particularly when the
inflation pressure is too low.
• Use the specified tires.
The tire inflation pressure and permissible speeds
are general values. The actual values may differ
depending on the type of tire and the condition which
they are used. For details, please consult the tire
manufacturer.
When tires become hot, a flammable gas is pro-
duced, and may ignite. It is particularly dangerous if
the tires become overheated while the tires are pres-
surized. 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 pro-
hibited 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, con-
sult 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” 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 should fall, flee the area as quickly as
possible. The tires for off-road equipment are
extremely heavy. Never attempt to hold a tire
upright when the tire is falling. This may lead to
serious injury or death.
