The tires should also be balancedperiodically. An unbalanced tire and
wheel assembly may result in irregulartire wear.
Tire Rotation

Always performthe system reset procedure after tirerotation. If you do not reset the system,it may not provide a low tire pressurewarning when necessary.
Note:If your tires show uneven wearask an authorized dealer to check forand correct any wheel misalignment,tire imbalance or mechanical probleminvolved before tire rotation.
