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 cracks, wear
or
severe rust. Never install a tube in a
cracked
wheel
rim. Never
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 spe
ed
and
with
great force. An air leak
of
this nature can thrust the tire in any
direction, endangering anyone in the
area.
