This program is designed to improve the quality of
balancing without any mental effort or loss of time by
the operator. In fact by using the normal commercially
available weights, with pitch of 5 in every 5 g, and by
applying the two counterweights which a conventional
wheel balancer rounds to the nearest value, there could
be a residual static unbalance of up to 4 g. The damage

4.8 - ECCENTRICITY MEASUREMENT ►
4.8.1 - WHEN AND WHY MATCHING
►
The software associated with eccentricity measurement is a powerful tool for determining the need to perform relative
rotation between the rim and tyre in order to reduce the eccentricity of the wheel down to acceptable limits. The principle adopted is based on the consideration that a rim with acceptable tolerance, mounted with an acceptable tyre,
can statistically generate a total eccentricity which is not acceptable but can be improved by matching.
Generally speaking, rim measurement is not necessary, accurate or useful because:
• To measure the rim it is necessary to remove the tyre. There can by coarse errors on the outside (e.g. aluminium
wheels!)
• The two rim sides can be eccentric in a very different way. Therefore to which one to make reference? What is the
effect on the tyre mounted?
• To improve the eccentricity of a wheel, the rim should be eccentric, to compensate the tyre. And viceversa.
• If after a rotation by 180° of a wheel, the value is still out-of-tolerance, either the tyre or rim are too eccentric: One
of the two must be replaced!

SOLUTION:

4.8.1.1 - PRESETTING OF TOLERANCE ON THE MACHINE
►
RESULT:
no improvement is obtained
There is no general rule concerning acceptability of an eccentricity value . As a fi rst approximation we consider it
correct to use a threshold of 1 to 1.5 mm / 0,0375” ÷ 0,056”. The E/ECE/324 standard prescribes 1.5 mm / 0,056” as
max. eccentricity of a rebuilt tyre.
4.8.1.2 - VALUE OF STATIC UNBALANCE, CORRELATED WITH ECCENTRICITY
►
Clear indication is given in the Measurement screen of both the value and position of the static unbalance as well
as the eccentricity. In fact, it is interesting to check the correlations of the two values, above all of the two positions.
When the two positions have a similar angle (± 30° one from the other), there is a clear sign that an eccentricity is
present which can be compensated by matching.
4.8.1
► .3 - VALUE OF UNBALANCE CORRESPONDING TO ECCENTRICITY
For user’s reference, the centrifugal force is calculated corresponding to a certain speed, compared to the force
generated by the eccentricity present on the tyre (calculated with an approximate average elastic constant).
I 0709 - 22GB
4.8.2 - WHEEL ECCENTRICITY MEASUREMENTS
►
The external radial and lateral eccentricity measurements are automatically made at the end of the unbalance measurement without having to perform particular procedures. Remember to position the sonar sensors in front of the
surface to be measured before pressing the
button.
The much enlarged fi gures show the outer tyre surface and axis of wheel rotation.
Fig. A - shows measurement of the total Peak-to-Peak eccentricity defi ned as maximum radial deviation of the tyre

Fig. B - shows measurement of the eccentricity of the 1st
harmonic, i.e. the eccentricity of that circle which “recopies”
A B
the tyre shape, by averaging the local deviations of the
tyre from the round shape.
Obviously the P.P. measurement is normally greater than
that of the 1st harmonic. Tyre manufacturers normally
supply two different tolerances for the two eccentricities.
The maximum limit of the fi rst harmonic can be set (
the wheel balancer displays the red symbol above the

The function of the LED is to make it easier to position the sonar correctly, but always bear in mind that it does not
indicate the focus of the pad as it is situated 30 mm further down. Correct positioning is highlighted on the screen by a
specifi c icon turning green.
The rim eccentricity measurement is important in order to try and reduce the total eccentricity of the wheel simply by
turning the tire on the rim.
Press the button ▪

button and slowly turn the wheel by hand, keeping a constant pressure on the gauge tip.
The total eccentricity, the rim and the tire values are simultaneously showed. Before passing to tire rotation on the
rim, check that the rotation result indicated on-screen is within tolerance. It is possible to set the minimum correction
limit below which it is never considered appropriate to intervene (

5.4.2 - UNBALANCE DISPLAY PITCH
►
This represents the unbalance display pitch and varies in relation to the unit of measurement selected. The selection
“5 g” (1/4 oz) enables display of the correction values on both sides such as to bring the static unbalance to 0 (theoretical). It is recommended to preset this function as standard on the machine as it improves the balancing
quality. The computer makes a complex calculation which allows cancelling the residual static unbalance by
varying the value and position of the counterweights fi xed in steps of 5 grams (1/4 oz).

5.5 - CORRECTION METHOD ►
One of the three possible correction methods can be selected based on the specifi c requirements of the customer.

► - STANDARD CORRECTION METHOD
The wheel balancer considers the unbalance within tolerance when the value of each single plane is lower than the
tolerance set.
5.5.2 - EXTERNAL PLANE CORRECTION METHOD
►
If correcting with adhesive weights, the unbalance is considered within tolerance when the recalculated external
plane weight (clip-on weights) is lower than the tolerance set.
Additional windows appear on the screen always displaying the residual external plane value (clip-on weight):
I 0709 - 32GB
►
5.5.3 - IC (INTELLIGENT CORRECTION) CORRECTION METHOD
The correction plane unbalance is considered within tolerance when both the STATIC and the DYNAMIC TORQUE
unbalances are lower than the tolerance set.
This correction method allows considerably reducing the weight to be applied, yet maintaining excellent balancing
quality. An icon appears on the screen showing the value of weight saved with respect to standard balancing.
When the button
appears, it means that the wheel balancer is suggesting static balancing, however, such that
also the dynamic torque unbalance will be brought within tolerance. When pressing this button, the position repeater
frame is accessed which clearly indicates where the weight should be positioned in the rim.
When the button
static and dynamic torque unbalances (
is pressed, as well as the actual unbalance values a window is also displayed indicating the
).
NOTE: The innovative IC software has been designed to reduce the amount of weight used to correct the
unbalance, leaving a residual unbalance on the wheel within the set tolerances.
The tolerance used by the machine is obtained from a tolerance of a reference wheel, modifi ed in
order to make the vibration generated by the reference wheel comparable with that in use.
This is obtained according to the coded theory of the ISO standards.
In general, a wheel balanced using IC has a higher residual unbalance than a wheel balanced at
best using the conventional method, but, although generating a tolerable vibration from the vehicle,
it has the advantage of considerably reducing the counterweights used.
