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
x
Switch tires only between the front and rear positions. Do
not switch the tires between diagonal positions.
x
Align the tire rotation direction with the tire tread
design pattern. Tread design pattern direction (optional)
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.
