Even if you like to have a go at things yourself, it is not recommended to try to balance your tyres by yourself. This should only be done by professionals who have the specialist equipment. After all, it's for your safety, driving comfort and the mileage of your wheels.
Garages usually use the stationary method for balancing tyres. This is done by clamping the wheel in a balancing machine and making it run. Special sensors check the tyre profile and the rim for irregularities. If an imbalance is detected, small weights are attached to the rim in specific spots. They ensure that the wheel rolls smoothly.
An alternative to the stationary method is electronic fine balancing. With this method, the wheel remains attached to the car during testing. The advantage here is that any irregularities in the wheel hub, brake drum and disc brake can also be detected and eliminated.
