PRECAUTIONS WHEN HANDLING TIRES
k k
If a tire reaches the using limit shown below, it may be
damaged and may cause an accident.
For safety, replace such a tire with a new one.
• Service limit for wear
• When the remaining depth of the grooves on con-
struction equipment tires (at a point approximately
1/4 of the tread width) is 15 % of the groove depth
on a new tire
• When an abnormal wear such as uneven wear or
stepped wear is found on a tire or when the cord
layer of a tire is exposed
• Service limit for damage
• When a damage or crack of a tire has reached the
cord
• When a damage on or dragging of cord is found
on a tire
• When tires are peeled (separated)
• When a damage is found in the bead of a tire
• When air leakage or an unrepairable damage is
found on a tubeless tire
• Do not install the tire protector (mesh chain) to rear
wheels.
• Do not to use tires, such as urethane tires, that weigh
remarkably more than the standard tires since the ma-
chine can be damaged due to an unexpected load.
• If a tire not specified by Komatsu is used, rim dis-
placement may occur between the tire and rim. Opera-
tor comfort may be degraded as well.

Contact your Komatsu distributor when replacing the tires. It is dangerous to jack up the machine without taking
due care.
TIRE PRESSURE
Check the tire inflation pressure before driving, when the tires are cool.
Excessively low tire inflation pressure induces overload on the tire, and excessively high pressure causes tire
cut (surface damage) and shock burst. To prevent these problems, adjust the tire inflation pressure referring to
the following table.
