Wheel balancer


Currently in the market today, there are two types of wheel balancing machines for cars, there is the standard semi-automatic version and the much more advanced fully automatic version. However, before we look at the features and benefits of both machines, let’s remind ourselves of the principal behind a wheel balancing machine and what is the purpose of the machine.

In essence, wheels and tires are never exactly the same weight all around, and as a result of this small imbalance occurs at high speeds, which can easily become large imbalances causing the wheel and tyre to spin with a kind of “galumphing” motion. This usually translates into a vibration in the car, which if not fixed can lead to some very irregular and damaging wear on the tyres.

So to avoid this imbalance, small weights are added to the wheel rim using a wheel-balancing machine. It works by equalising the weight of the combined tyre and wheel so that it spins smoothly at high speed. To achieve this, the complete wheel and tyre are put on a balancing machine, which centres the wheel and spins it at high speed to determine where the weights should be fixed.

So now that we know the purpose of a wheel balancer, let’s take a look at the two most common machines that are currently available and see how they work. Starting with the older semi-automatic version. In the simplest of terms, each of the car or truck wheels complete with the tyre is removed from the car and attached individually to a spindle that comes out of the side of the balancing machine. The wheel is then run at high speed and from this, a digital display gives a reading that identifies any imbalances, and where the weights should be added to the wheel to correct this. Once all four wheels have been balanced, they are put back on the car or truck.

With regards to the more advanced fully automatic wheel balancing machine, the principal of checking each wheel stays the same, what changes are the fact that it is technology-driven and the design can give the workshop operator much more information than simply where to apply the weights. It also takes much of the guesswork away by using a led light and a laser to precisely pinpoint the positioning of the adhesive weights, ensuring equal wear on all four tyres.

Both types of machines can be found in a professional tyre and service shop and when it comes to using either type of wheel balancing machine, you should never try to operate this equipment yourself, it should always be left up to a trained professional tyre installer to use.

When it comes to choosing which wheel balancer is right for you, there is a range of reputable brands here in Australia and several international products to choose from, but, always make sure you buy the equipment from a recognised dealer, that the build quality is CE Certified and that it is manufactured according to ISO9001. You should also look for a wheel-balancing machine that comes with a minimum 2-year warranty.
