light coat of chassis grease, never-seize or disc brake corrosion control
grease, only to the wheel locator pad.
When installing the tire and rim assembly on disc-brake equipped axles,
make sure the tire valve stem clears the brake caliper. The use of a tire
manufacturer's stem forming tool is the only acceptable method of
obtaining clearance when necessary.
Note: Always observe the following instructions:
Failure to follow these instructions could result in property
damage, personal injury or death
• Always loosen rim clamps before complete removal of nut from stud
(cast spoke wheels). With loosened nuts on stud, strike clamps with a
heavy hammer and be sure each clamp is loose.
• Always deflate tires completely before removing locks or side rings.
• Always inflate tires in a safety cage.
• Never mix rim side rings or lock rings of different types,
manufacturers or sizes.
• Never use cracked, bent or badly rusted parts.
• Never re-inflate flat tires on-vehicle; use the spare tire.
• Never add air until each side ring or lock ring is fully seated.
• Never hammer side ring or lock ring on a partially- or fully-inflated
tire.
Proper torque
It is important to tighten and maintain wheel and rim mounting nuts to
the proper torque. Loose nuts or over-tightened nuts can lead to
premature wear and possible failure of the wheel and/or mounting
hardware.
Changing wheel types
Consult your dealer or wheel/rim distributor before attempting any wheel
or fastener changes.
Use only the same type and style wheels and mounting hardware
to replace original parts. Failure to do so may result in an
assembly that looks fine, but does not fit together properly. This could
possibly cause wheel or fastener failures which could result in property
damage, personal injury or death.
