OPTIMISATION PROGRAMME "OPT"
This procedure minimises any vibration still present on the vehicle while running even
after accurate balancing, thus minimising the rim-tyre coupling run-out.
Based on our experiences, the programme can be recalled every time it is convenient to

The calculations performed by this programme are based on the unbalance values measured
during the last spin performed which must therefore refer to the wheel being serviced.
