General Information
Balancing Tires and Wheels
Caution: Failure to adhere to the following
precautions before tire balancing can result in
personal injury or damage to components: (
• Clean away any dirt or deposits from the inside
of the wheels.
• Remove any stones from the tread.
• Wear ey~ protection.
• Use coated weights on aluminum wheels.
Important: The tires can be balanced either on-vehicle
or off-vehicle, but the off-vehicle balancing procedures
are recommended. Off-vehicle methods are better
because tire rotation will not affect the balancing. The
off-vehicle balancers are also more accurate than
the on-vehicle balancers. Off-vehicle balancers
can perform dynamic balancing as well as static
balancing.

Tire and wheel balancers can drift out of calibration
without warning, or can become inaccurate as a result
of abuse. The balancer calibration should be
inspected every two weeks, and whenever the
readings are questionable.
