Tire Rotation - Hitachi ZW 310-6 Operator's Manual

Tire Rotation

Rotate tires when uneven or abnormal wear is
recognized on either front or rear, or right and left tire.
Tire rotation is recommended to achieve uniformity of
wear on tires for good tire service life.

WARNING: This must have no external damage,
such as heavy cuts, large bubbled protrusions or
other damage that can lead to tire failure. If tires
have such problems, they may fail with a blow-out,
and cause an injury or death, or otherwise damage
property.
Rotation Procedure
 Switch tires only between the front and rear positions.
Do not switch the tires between diagonal positions.
 Align the tire rotation direction with the tire tread
design pattern. Tread design pattern direction
(option) will affect not only economy of tire but also
safety of operation.
How to Check Wear Amount (Tread Design Groove
Depth):
Measure the groove depth at 1/4 tread width position
[shown with X mark (1) in the figure].
Use limit of the groove depth shall be approx. 85 % of the
new tire groove depth. In case extreme uneven wear or
exposed rubbing strips are found, replace the tire even
before reaching 85 %.
IMPORTANT: The tire sizes must be close to even,
or mechanical damage will result to the drive
train. When installing replacement tires, be sure
that the tire sizes and design are the same. It is
recommended to replace all four tires at the same
time.
