Why should you balance tyres at all?

At a speed of 100 km/h the centrifugal force of a 10 g unbalance acts like the force of a sledge hammer. This makes wheels without balancing weights a danger: Impact weights for steel and aluminium rims prevent higher stress on wheel suspensions and bearings. Missing balancing weights on steel and aluminium rims can also lead to noticeable vibrations at the steering wheel and in the interior. In addition, the absence of impact weights on steel or aluminium rims results in increased brake and tyre wear.

Assembly of impact weights:

First of all, the suitable impact weight for steel rims or aluminium rims must be selected. The balancing weight must fit the rim shape, whereby a distinction is made between the rim design and rim flange shape. Then place the balancing weight on the rim to check the fit.

Then place the balancing weight in the required position on the steel or aluminium rim. Before hitting the weight, make sure that the clip is correctly positioned on the rim flange.

Once the weight is correctly aligned, it is struck with a suitable mounting tool (balancing weight tongues or Hammer). For mounting the impact weights, a maximum of two strong blows should be applied. Increasing the stroke rate can damage the coating of the balancing weights.
