5.11.1
General
Optimization
is
a
finer
form
of
matching.
During
the
opto–ride
procedures
the
rim
and
tyre
are
adjusted
relative
to
each
other
on
the
basis
of
different
unbalance
measurements.
This
generally
means
that,
where
present,
lateral
and
radial
run–out
and
radial
and
lateral
force
variations
are
reduced
and
thus
wheel
running
conditions
optimized.
In
addition,
the
mass
(balance
weight)
necessary
for
balancing
can
be
reduced.
If
optimization
is
not
desired,
it
is
possible
to
achieve
weight
minimization
(so–called
matching).This
is
e.
g.
possible
if
the
rim
does
not
exhibit
geometric
deformations,
in
other
words
when
unsmooth
wheel
running
conditions
are
a
result
of
a
non–uniform
tyre.
In
this
case
the
unbalance
of
the
rim
can
be
readjusted
relative
to
the
unbalance
of
the
tyre
such
that
the
unbalances
compensate
each
other
and
the
smallest
possible
weight
for
unbalance
correction
is
determined.

Instructions
for
the
optimization
/
weight
minimization
programs
Compensation
of
unbalance
of
the
clamping
device
is
cancelled
by
starting
an
optimization
or
minimization
run
(C4
7.1.1).Preparation:
Make
sure
the
tyre
is
correctly
mounted
on
rim
and
inflated
to
specified
inflation
pressure
(mounting
guide
rib
of
the
tyre
must
be
correctly
seated).Clamp
the
wheel.
Enter
correct
rim
dimensions,
or
check
existing
inputs
for
correctness.
Select
the
MODE
‐
key
until
the
Minimization
indicator
blinks.
The
“M”
indicator
will
start
blinking.
The
display
now
equals
Figure

‐
31.Note:
The
MODE
‐
indicator
will
be
on and
the
Minimization
indicator
will
blink.
If
the
Minimization
indicator
does
not
blink,
check
if
a
NORMAL
wheel is
selected.•
