When the tire and the rim are assembled together, there may be imbalance on the weight distribution of radial and lateral centers of the wheel. Imbalance causes vibration at high speeds and premature tire wear as well as causing wear of the car�s suspension system.
Therefore, tire balance must be checked at the beginning of the vibration.
There are two types of imbalances on the wheels; �Static Imbalance� and �Dynamic Imbalance�.
Static Imbalance; occurs when there is an imbalance on the weight distribution of the radial center and it causes the wheel tend to jump.
Dynamic Imbalance; occurs when there is an imbalance on the weight distribution of the lateral center of the wheel and it causes wheel wobble.
To balance the wheel, equal weight distribution must be ensured by balancing machine and wheel balance weights.
After the wheel is mounted on a balancing machine and is spinned, wheel balance weights are assembled on the opposite side of imbalance.
