Tire
inflation

Correct
tire

pressure
is

very
importan
t
to

ease
of

steering
and

riding
comfort
This
also
reduces

driving

sound

to
a
minimum

resulting
in

longer
tire
that

is

overinfla

promotes
wear
at
center

If
all
tires
are

inspected
frequently
and
maintained

correct
tire

pressure
it
is

possible
to
detect

sharp
material

in
the
tread

Also
the
above

check
avoids
abnormal
wear

which

invites
serious
trouble

If
tires
indicate
abnormal
or

uneven
wear
the

cause
of
trouble
should
be
detected
and

eliminated

After

cd
Without

valve

caps
leakage
will

occur
due
to

Accordingly
whenever

Tires
of
radial

ply
construction

will
revolve
with
less

camber
thrust
force
and
with

greater

cornering
power
on

turns
This
tends
to
cause
local

Exercise

Note

Radial

tires

should
not
be
mixed
with

since
their
characteristics

b
The

Uneven

Meanwhile

the

Accordingly
to

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

wheel
balancer

Wheel

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

depends
on
a

good
seal
between

and

Thoroughly

remove
rust

oxidized
rubber
or

sand
from
wheel
rim

with
wire

brush

emery
cloth
or

paper
Use
dial

to

examine
