Note:Make sure the tire valve stem clears the brake caliper when
installing the tire and rim assembly on disc-brake equipped axles. The
use of a tire manufacturer’s stem forming tool is the only acceptable
method of obtaining clearance when necessary.
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 or mounting hardware.
Changing Wheel Types
WARNING: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.
Note:Do not attempt to mix stud-piloted wheels or fasteners with
hub-piloted wheels or fasteners.
Note:Do not change from aluminum wheels to steel wheels or
vice-versa without changing the mounting hardware required or, with
flange nut mounting systems, changing the hub and stud assembly.
Consult your dealer or wheel or rim distributor before attempting any
wheel or fastener changes.

Note:Do not use lubrication on dry threads. Where excessive corrosion
exists, a light coat of lubricant on the first three threads of the stud bolt
is permitted. Keep lubricant away from:
•Hex nut and rim clamp contact surfaces.
•Cap nut ball face and ball seat on the disc wheel.
•Flange nut washer surface and flat on the disc wheel.
