5.7 - Unbalance optimisation
- This function serves to reduce the amount of weight to be added in order to balance the wheel
- It is suitable for static unbalance greater than 30 g.
- It improves the residual eccentricity of the tyre.
- With a piece of chalk make a reference mark on the flange and the rim
- With the aid of a tyre remover, turn the tyre on the rim by 180°
- Refit the wheel in such a way that the reference marks on the rim and
the flange coincide.
- RH display: percentage reduction value
- LH display: actual static unbalance value which can be reduced by
rotation
