WHEEL BALANCING

What is wheel balancing?

Wheels and tyres, as with any rotating object, need to be balanced in order to reduce vibration. A good example of this is when laundry is loaded into a washing machine unevenly, the drum is not correctly balanced, so vibrates. Similarly, wheel balancing ensures that the weight of the wheel and tyre is even around the axle.

Why is wheel balancing important?

You should always have your wheels balanced whenever you have new tyres fitted. Car tyres which are fitted on wheels that have not been properly balanced will wear very quickly and unevenly. This is due to the inconsistent points of friction between the tyre and the road, creating an effect like rubbing sandpaper on the tyre aggressively. Losing grip this way could be very dangerous and the vibration also makes the car’s ride very uncomfortable, possibly to a point of distraction that might lead to an accident.

How are wheels balanced?

Wheels are typically removed from a car before their balance is checked. They are placed in a specially-designed machine and spun to measure the vibration. Small offsetting weights are placed at points on the rim of the wheel based on results from the balancing machine. This is repeated until the machine reports that the wheel is balanced.

What causes wheel balancing problems?

• If your car’s tyres have been replaced and not balanced.
• If the height of your car has been altered without rebalancing the wheels.
• Items on the road can be hazardous if hit.
• Aging, worn or damaged parts can impact your car’s suspension and, therefore, its wheels.
