N
⋅
m)
Follow the proper bolt tightening sequence
shown.
NOTE: When installing wheel, be sure valve
stem (C) points away from wheel support.
Tire Inflation
Check tire pressure daily. Maintain 100 psi (690
kPa).
WARNING: Service tires safely. A
tire can explode during inflation
and cause serious injury or death.
Never increase air pressure
beyond 35 psi (241 kPa) to seat the bead on
the rim. Replace the tire if it has a defect.
Replace a wheel rim, which has cracks, wear
or severe rust. Never weld a wheel rim. Make
sure all the air is removed from a tire before
removing the tire from a 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 is 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.
(A) - Use a safety cage if available.
(B) - Do not stand over tire. Use a clip-on chuck
and extension hose.
