288 Vehicle Care
Warning (Continued)
Consult your dealer before
replacing wheels. Never use
wheels that are not designed for
the vehicle. Doing so would
impede safe vehicle operation.
You should replace your tires when:
. Your tires are worn to a point
where 3.2 mm (4/32 in.) (front)
and 1.6 mm (2/32 in.) (rear) or
the cord or fabric is exposed.
. Your tire tread or sidewall is
cracked, cut or snagged deeply
enough to expose the core,
fabric or steel components.
. Your tire has a hump, bulge or
split.
. Your tire sustains a puncture, cut
or other damage that cannot be
correctly repaired because of the
size or location of the damage.
When replacing tires, you should
use the same size, load range and
construction type (bias or radial) as
the original tires on your vehicle. Use of any other size or type tire
may affect load carrying capacity,
ride, handling, speedometer/
odometer calibration, vehicle ground
clearance and tire clearance to the
chassis. If replacing only a single
tire, it should be put on the same
axle with other tires of equal
diameter.
When replacing or rotating tires, all
tires on an axle should be of the
same tread design and should have
the same outside diameter within
certain limitations, particularly on
LSD models. Consult your
authorized dealer or tire dealer.

Emissions Plate” for the location of
the Greenhouse Gas (GHG)
emission plate. See Vehicle
Identification Number (VIN) 0343. Wheel Replacement
Recommendations
Wheels must be replaced if they
become damaged (for example:
bent, heavily rusted, leak air) or if
wheel nuts often become loose. Do
not use bent wheels that have been
straightened and do not use inner
tubes in leaking wheels which are
designed for tubeless tires. Such
wheels may have structural damage
and could fail without warning.
When replacing wheels for any
reason, the new wheels should be
equal in load capacity, diameter, width, offset and mounting types to
those originally installed in your
vehicle.
A wheel of the wrong size or type
may adversely affect wheel and
bearing life, brake cooling,
speedometer/odometer calibration,
stopping ability, headlight aim,
bumper height, vehicle ground
clearance and tire or tire chain
clearance on the body and chassis.
Replacement with "used" wheels is
not advised. They may have been
subjected to harsh treatment or very
high mileage and could fail without
warning.
