What is wheel balance?
At a cruising speed of 100 kph, your car wheels rotate 15 times per second! At this spin-speed, even the slightest anomaly in shape or weight (balance) will cause them to vibrate.

The imbalance may be so slight that it is undetectable to the driver, especially on a poor road surface: or it can be so severe that, within certain speed bands, it causes the steering wheel to shake quite violently.

Why is balance important?
Whether the imbalance is slight or severe, vibration causes discomfort to the driver, increases tyre wear, reduces handling integrity, adds rolling resistance and thus increases fuel consumption, and over time can damage other mechanical components and the bodywork.

Vibration means that as the tyre wheel assembly is going round and round, it is also shaking very slightly from side to side - 500 times every kilometer, many millions of times in the life of the tyre. This not only scrubs the tread causing much faster wear, but also transmits millions of tiny hammer blows to the wheel bearings, ball joints, steering mechanism, bushes, mountings...and shakes every weld and nut and bolt and seal in the vehicle, causing rattles and ageing.

How is balance corrected?
Special equipment is used to establish the exact location and degree of weight variations in the wheel-tyre assembly, and small off-set weights are attached to the wheel rim to correct the errors. The process takes just a few minutes per wheel.Read More || Close

The exact size and position of the weights is crucial. For perfect balance, accuracy to within one gram and one milimetre is necessary. Conventional wheel-balancing equipment is accurate enough to remedy severe vibration, but only more sophisticated computerized systems - operated by skilled technician - can get it absolutely right and prevent not only the vibrations you can feel, but also those you can't.

AutoXpress Balancing
Autoxpress use the most advanced computerized wheel-balancing equipment on the market, and all operators undergo intensive training which includes both technical know-how and performance discipline. This ensures they not only "can" do the job right, but also that they "do" get it right - quickly, neatly, exactly and every time!
