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

underinOation

Accordingly
whenever

tire

pressure
is

checked
be
sure
to

secure
valve

caps
and

tighten
firmly
by
hand

Tubeless

In
urder

to

inspect

where

leakage
occurs

Wipe

use

the
tire

repair

kits
which
are

should
be
made

to

secure
complete

sealing
The

flange
should

be
cleaned

by
a
wire

Tires
of
radial

ply
construction

will
revolve
with
less

camber
thrust
force
and
with

greater

cornering
power
on

turns
This
tends
to
cause
local
or

rapid
wear
on
the

treads

with
excessive

toe

Exercise

special
care
for
front

alignment

during
the
life
of
tires
Note
a
Radial

ply
tires

should
not
be
mixed
with

ordinary
tires

since
their
characteristics
differ
from

those
of

ordinary
tires

b
The
same
brand
radial

ply
tires
should
be

installed
on
all
wheels

c

The

designed
for

should
be
used
