19.0 MATCHING PROCEDURE (Rim - Tyre
Optimization)
The “MATCHING” procedure offsets strong unbalance,
reducing the weight quantity to be fitted on the wheel
to achieve balancing. This procedure permits reducing
unbalance as much as possible by offsetting the tyre
unbalance with that of the rim.
Proceed to dynamic unbalance measurement dis
-
playing by performing a standard wheel spin (see
Par. 15.3.4).
THE MATCHING PROCEDURE CAN
BE CARRIED OUT ONLY IF THE
STATIC UNBALANCE IS > 30 G.
Once the unbalance values have been determined,
press the OPTIONS key
several times. The LED

in line with the arrow on the flange, so as to be able
to fit the rim back on in the same position on the
machine. Press key
to confirm that step 1 has
been completed.
