In the case of a narrow wheel, balancing simply involves moving the center of gravity to the centre ...

Tire balance. Tire balance, also called tire unbalance or tire imbalance, describes the distribution of mass within an automobile tire or the entire wheel (including the rim) on which it is mounted.

Unbalance causes a moment which gives the rotor a wobbling movement characteristic ...
