12.1 Vibration Causes
There are many causes for vibration. Vibration can also be
caused by tire wear, among other things. Tire wear caused by
driving does not always develop evenly over the entire tread. Due
to this, a slight imbalance develops which disturbs the smooth‐
ness of the formerly accurately balanced wheel.
This slight imbalance cannot yet be felt in the steering wheel, but
it is present. It increases the tire wear and consequently reduces
the service life of the tire.
Recommendation
In order to guarantee over the entire service life of a tire a
• Optimal safety,
• Optimal smoothness and
• Uniform wear
it is recommended that wheels/tires be balanced at least two
times within the tire's service life.
12.2 Balancing
Before beginning balancing, the following requirements must be
fulfilled.
• The tire pressure must be OK.
• The tire tread must not be worn down on one side and should
be at least 4 mm deep.
• The tires must not have any damage such as cuts, holes, for‐
eign bodies, etc.
• The suspension, steering, tie rods and damper must be in
proper working order.
• A road test has been performed.
