TIRE

INFLATION

Correct
tire

pressure
is

very
im

portant
to
ease
of

steering
and

riding

comfort

This
also
reduces

driving

sound

to
a
minimum

resulting
in

longer
tire

life
that
is

overinflation
or
underinflation

promotes
wear
at

cen

ter
tread
or

shouider
of
tire

If

aU
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

problem
If
tires
indicate

abnormal
or

uneven

wear
the
cause
of

problem

should
be
detected
and
eliminated

After

inflating
tires

leakage
in
valve

should
be

checked
Without

valve

caps

leakage
will

occur
due
to

dirt
and

water

resulting
in

underinflation
Ac

cordingly
whenever
tire

pressure
is

checked
be
sure
to

tighten
valve

caps

firmly
by
hand
