WHEEL BALANCER

Professionals use computerized wheel balancers to pinpoint weight differentiation within a tire and wheel assembly.

Computerized wheel balancers are highly accurate machines that identify the weight distribution problem areas within an assembly.

Ideally, a tire and its wheel should complement one-another, with both maintaining an equal amount of weight throughout the assembly. In a perfect assembly, air will be even throughout the tire, and the wheel will be perfectly round in shape. However, tires and wheels are nearly never perfect.

In fact, some tire manufacturers mark the lightest part of a tire so that drivers can easily match it to the heaviest part of the wheel. Both time and normal tire and wheel usage will also gradually add imbalance to a tire and wheel assembly’s weight distribution.

The smallest difference in weight within an assembly can cause a great amount of damage and annoyance. A computerized wheel balancing service will return the balance of your car or truck’s wheels to factory specifications

When the wheel rotates, asymmetries in its mass distribution may cause it to apply periodic forces and torques to the axle, which can cause ride disturbances, usually as vertical and lateral vibrations, and this may also cause the steering wheel to oscillate. The frequency and magnitude of this ride disturbance usually increases with speed, and vehicle suspensions may become excited when the rotating frequency of the wheel equals the resonant frequency of the suspension
