If

After

ROTATION

Tires
tend

to
wear

unevenly
and

become
unbalanced
after
a
certain

running
distance
Uneven

tire
wear

often
results
in
tire
noise
which
is

attributed
to

rear

gears
bearing

etc

Front
tires
also

tend
to

unevenly
because
of

Accordingly
to

equalize

wear

it
is

necessary
to

WHEEL
BALANCE

The

assembly
should

be

kept
balanced

statically
and

dy

namically

Proper
tire
balance
is

necessary

when

driving
the
car
at

high

speeds

Consequently
the

wheel
and
tire

as

sembly
should
be

properly
rebalanced

whenever

puncture
is

repaired

The
wheel
and
tire

assembly
be

comes
out

of
balance
according
to

uneven

wear
Severe
acceleration

and

braking
or
fast

cornering
is

the

cause
of
