WARNING!
Use only the wheel brand, size and
part number originally installed. Use
of a different wheel brand or size could
cause valve stem to interfere with a
brake component which could lead to
loss of vehicle control. Failure to com-
ply may result in death, personal injury,
equipment or property damage.
Vehicles equipped with front disc
brakes are fitted with wheels designed
specifically for disc brake applications.
If it ever becomes necessary to
replace an original equipment wheel,
the replacement wheel must be the
same brand and size as the take-off
wheel. On vehicles equipped with 22.5
in. disc wheels, installing the wrong
replacement wheel could result in
the wheel valve stem making contact
with the disc brake assembly. When

TIRES AND WHEEL
installing any replacement wheel,
always inspect the tires/wheels to
ensure there is adequate clearance
between other vehicle components.
With the hood open, check for
clearance between the wheel and disc
brake assembly. Use a hydraulic jack
to raise the front of the vehicle off
the ground to allow the wheel to spin
freely. While rotating the wheel, check
to ensure there is adequate clearance
between the wheel and disc brake
assembly.
