Volkswagen Polo Service & Repair Manual: Vibration, Causes for Vibration

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 smoothness 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.
