Spare Tire Matching Original Equipped Tire And
Wheel — If Equipped
Your vehicle may be equipped with a spare tire and
wheel equivalent in look and function to the original
equipment tire and wheel found on the front or rear
axle of your vehicle. This spare tire may be used in the
tire rotation for your vehicle. If your vehicle has this
option, refer to an authorized tire dealer for the recom-
mended tire rotation pattern.
Compact Spare Tire — If Equipped
The compact spare is for temporary emergency use
only. You can identify if your vehicle is equipped with
a compact spare by looking at the spare tire description
on the Tire and Loading Information Placard located on
the driver ’s side door opening or on the sidewall of the
tire. Compact spare tire descriptions begin with the
letter “T” or “S” preceding the size designation. Ex-
ample: T145/80D18 103M.
T, S = Temporary Spare Tire
Since this tire has limited tread life, the original equip-
ment tire should be repaired (or replaced) and rein-
stalled on your vehicle at the first opportunity.Do not install a wheel cover or attempt to mount a
conventional tire on the compact spare wheel, since the
wheel is designed specifically for the compact spare
tire. Do not install more than one compact spare tire and
wheel on the vehicle at any given time.
WARNING!
Compact and collapsible spares are for temporary
emergency use only. With these spares, do not drive
more than 50 mph (80 km/h). Temporary use spares
have limited tread life. When the tread is worn to
the tread wear indicators, the temporary use spare
tire needs to be replaced. Be sure to follow the
warnings, which apply to your spare. Failure to do
so could result in spare tire failure and loss of
vehicle control.
Collapsible Spare Tire — If Equipped
The collapsible spare is for temporary emergency use
only. You can identify if your vehicle is equipped with
a collapsible spare by looking at the spare tire descrip-
tion on the Tire and Loading Information Placard

244 SERVICING AND MAINTENANCE

When cleaning extremely dirty wheels including exces-
sive brake dust, care must be taken in the selection of
tire and wheel cleaning chemicals and equipment to
prevent damage to the wheels. Select a non-abrasive,
non-acidic cleaner for aluminum or chrome wheels.
CAUTION!
Do not use scouring pads, steel wool, a bristle
brush, metal polishes or oven cleaner. These prod-
ucts may damage the wheel’s protective finish.
Such damage is not covered by the New Vehicle
Limited Warranty. Only car wash soap is recom-
mended.
NOTE: If you intend parking or storing your vehicle for
an extended period after cleaning the wheels with
wheel cleaner, drive your vehicle and apply the brakes
to remove the water droplets from the brake compo-
nents. This activity will remove the red rust on the
brake rotors and prevent vehicle vibration when brak-
ing. Dark Or Low Gloss Wheels
CAUTION!
If your vehicle is equipped with these specialty
wheels, DO NOT USE wheel cleaners, abrasives, or
polishing compounds. They will permanently dam-
age this finish and such damage is not covered by
the New Vehicle Limited Warranty. HAND WASH
ONLY USING MILD SOAP AND WATER WITH A
SOFT CLOTH. Used on a regular basis; this is all
that is required to maintain this finish.
Tire Chains (Traction Devices)
Use of traction devices require sufficient tire-to-body
clearance. Follow these recommendations to guard
against damage.

tion of 7 mm beyond the tire profile can be fitted on
