Tires, Wheels and Hub Maintenance
Wheel Safety Information
Do not attempt to repair wheels or tires
unless you are trained and equipped to
do so. Wheel and tire assemblies cannot
be worked on without proper tools and
equipment. Failure to follow this may
lead to serious personal injury or death.
Failure to properly torque-tighten the
wheel nuts can result in the breakage of
wheel studs and the subsequent loss of
wheels. Loss of vehicle control and seri-
ous personal injury or death can occur.
Do not use oil or grease on studs or
nuts. The tightening torque is affected
and can lead to incorrect clamping loads
between the rim and hub. This could
lead to a loss of the wheel. Loss of vehi-
cle control and serious personal injury or
death can occur.
Do not install regrooved, retreaded or re-
paired tires on the steering axle(s). They
could fail unexpectedly and cause the
loss of vehicle control, leading to seri-
ous personal injury or death.
Do not use mismatched wheel compo-
nents. If they do not exactly match the
original design specifications, they may
cause failure or separation leading to an
accident causing serious personal injury
or death.
Do not install tires with a load rating
that is less than stated on the Certifica-
tion Label in the door frame. The tire
could be unintentionally overloaded,
leading to an accident, causing serious
personal injury or death.
Do not use mismatched tires on the
same axle. Always use the same type
(radial or bias ply) or size. Mixing tires
on the same axle will affect the road-
holding and can lead to an accident
causing serious personal injury or death.
