Wheels and Tires: Testing and Inspection

Wheels and Tires, 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:

• Optimal safety.

• Optimal smoothness.

• Uniform wear.

It is recommended that wheels/tires be balanced at least two times within the tire's service life.
