TIRE
INFLATION
Make a visual
check
daily that tires have
not
lost
pressure. Under-inflation
of
drive tires can cause
side wall cracks.
Once
a year, measure tire pressure with a gauge.
NOTE:
If
tail wheels shimmy a possible cause Is
over-inflation. Maintain pressures recommended
in
Specifications Section.
A
WARNING:
Service
tires
safely. A
tire
can
explode during
inflation
and
cause
serious
injury
or
death
.
Never
increase
air
pressure beyond
35
psi
{240 kPa)
when
seating
the
bead
on
the
rim. Replace a tire
if
it
has
a defect. Replace a wheel rim
which
has
aacks, wear or severe rust.
Never
install a
tube
in
a
aacked
wheel rim.

weld
a
wheel
rim.
Make
sure
all
the
air is removed from a
tire
before
removing
the
tire
from the rim.
Never
use force
on
an inflated
or
partially inflated
tire
. Make sure
the
tire is correctly seated before inflating
to
operating
pressure.
Do
not
remove, install
or
make
repairs
to
a tire
on
a rim unless
you
have
the
proper
equipment
and
experience
to
perform
the
job
. Take
the
tire
and
rim
to
a qualified tire repair
shop.
If
the
tire is
not
in
correct position
on
the
rim,
or
if
too
full
of air,
the
tire bead
can
loosen
on
one
side, causing
air
to
leak
at
high
speed
and
with
great
force.
An
air
leak
of
this nature
can
thrust
the
tire
in
any
direction, endangering anyone
in
the
area.
