336 Vehicle Care
Use this rotation pattern when
rotating the tires (except
polished forged aluminum
wheels).
Vehicles with polished forged
aluminum wheels have two
unique wheels; an aluminum
front and rear outer wheels, and
steel rear inner wheels. The
aluminum wheels can only be
rotated from the front and rear
outer positions. The steel
wheels can only be rotated on
the rear inner positions.
Use this rotation pattern when
rotating the tires if the vehicle
has polished forged aluminum
wheels. The steel spare wheel
can be used in any position in
the event of a flat tire. An
aluminum spare wheel can be
used in front or rear outer
positions only.
When installing dual wheels,
check that the vent holes in the
inner and outer wheels on each
side are lined up.
Adjust the front and rear tires to
the recommended inflation
pressure on the Tire and
Loading Information label after
the tires have been rotated.
See Tire Pressure 0 332 and
Vehicle Load Limits 0 205.
Check that all wheel nuts are
properly tightened. See Wheel
Nut Torque under Capacities
and Specifications 0 408.
Warning
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose
after time. The wheel could come
off and cause a crash. When
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle. In
an emergency, a cloth or a paper
towel can be used; however, use
a scraper or wire brush later to
remove all rust or dirt.
Lightly coat the inner diameter of
the wheel hub opening with
wheel bearing grease after a
wheel change or tire rotation to
prevent corrosion or rust
build-up. Do not get grease on
the flat wheel mounting surface
or on the wheel nuts or bolts.
Check that the spare tire, if the
vehicle has one, is stored
properly.
