THE IMPORTANCE OF BALANCE
In
order
to
obtain good steering it Is of importance
to
ensure
that
the
wheels, with
tyres
fitted. are in
good balance. To assist this.
the
tyre
manufacturers
are now marking
their
tyres
with a
white
spot
or
spots
in
the
neighbourhood of
the
bead at
the
lightest
point
of
the
cover;
similarly. they are marking
the
inner
tubes
with a
group
of coloured spots
to
Indicate
their
heaviest point.
When
tyres
are assembled care
must
therefore
be taken
to
see
that
they
are
assembled
with
the
white
spots on
the
cover coinciding with
the
coloured
spots
on
the
tube, and not
opposite
to
the
valve as recommended
hitherto.
It must be noted, in addition,
that
special balancing
discs
are
fitted
to
the
inside of
the
cover
casing in
some cases and
that
these
should on no account be
re moved. as
the
ty re balance wi
II
be upset if this is
done. These balance discs are
not
repair patches and
do
not
indicate any fauIt in
the
tyre.
Special balance weights are supplied by
the
Dunlop
Rubber Co. for
attachment
to
the
wheel rim
under
Part Nos. WBW II
to
7. whlch
cover
a range of
weights weighing

to

Their
use is advised to obtain
the
best possible
balance for
the
front
wheels.
