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

If

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

TIRE
REPAIR

In
order

to

inspect
a
leak

apply

soapy
solution
to
tire
or

submerge
tire

and
wheei

in
the

water
after

inflating

tire
to

specified

pressure
Special
in

spection
for

leaks
should
be
carried

out
around
the
valve
wheel
rim
and

along
the
tread

Exercise
care
to
bead

and
rim
where

leakage
occurs

Wipe

out
water
from

area
which

leaks

and

then
mark
the

place
with

chalk

After

removing
the
materials
which

caused

When

repairing
the

puncture
use
the

tire

repair
kits

which
are
furnished
from

tire
dealers

following
the
instructions

provided
with
the

kits
In

case
that
a

puncture
becomes

large
or
there
is

any

other

damage
on
the

tire
fabric

repair

must
be

carried
out

by
authorized

tire

dealers

WHEEL
REPAIR

Inspect
the
wheel
rim

flange
for

bend

or
dents

The

flange
should
be
cleaned

by
a

wire

brush
when
rust
is
found

on
the

flange
Furthermore
if
excessive

pitting
occurs

on
the

rim
eliminate
it

with

TIRE
ROTATION

Tires
wear

unevenly
and
become

unbalanced

according
to

running
dis

tance
Uneven
tire
wear
often
results

in
tire
noise

which
is
attributed
to
rear

axle

gears
bearing
etc
Meanwhile
the

front
tires
tend
to
wear

unevenly

because
of

improperly
aligned
front

wheel

Accordingly
to

equalize
tire
wear

it
is

necessary
to

rotate
tires

peri

odically

All
the
tires

including
the

are
