INSPECTION

Wheel
balance

The
wheel
and
tire

assembly
should
be

kept
balanced

statically
and

dynamically

Proper
tire
balance
is

necessary
when

driving
the
car
at

high

speeds
Consequently
the
wheel
and
tire

assembly

should

be

properly
rebalanced
whenever

puncture
is

repaired

The
wheel
and
tire

assembly
becomes
out
of
balance

according
to
uneven
tire
wear

Severe
acceleration
and

braking
or

fast

cornering
is
the

cause
of
wear
on
tire

resulting
in
unbalance
of
tire
and
wheel

assembly

The

symptom
of

unbalance

appears
as

tramp
car
shake

and

steering
trouble

To
correct
unbalance
use

proper
wheel
balancer

In
order

to
ensure

satisfactory
steering
condition
as

well

as
maximum
tire
life

proceed
as
follows

I

Check
wheel
rim

especially
rim

flange
and
bead

seat

for
rust
distortion

cracks
or
other
defects
which

might

cause
air
leaks
Function
of

tubeless
tire

depends
on
a

good
seal
between

Thoroughly

remove
