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
lion
or

underinflation

promotes
wear
at
center

tread
or
shoulder

of
tire

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

inflating
tices

leakage
in
valve

should
be
check

cd
Without

valve

caps
leakage
will

occur
due
to

dirt
and

water

resulting
in

Accordingly
whenever

tire

pressure
is

checked
be
sure
to

secure
valve

caps
and
