Tread Wear Indicators
Tread wear indicators are in the original
equipment tires to help you in determining
when your tires should be replaced.
These indicators are molded into the bottom
of the tread grooves. They will appear as
bands when the tread depth becomes a
1/16 of an inch (1.6 mm). When the tread is
worn to the tread wear indicators, the tire
should be replaced. Refer to “Replacement
Tires” in this section for further information.
Life Of Tire
The service life of a tire is dependent upon
varying factors including, but not limited to:• Driving style.
• Tire pressure - Improper cold tire inflation
pressures can cause uneven wear patterns
to develop across the tire tread. These ab-
normal wear patterns will reduce tread life,
resulting in the need for earlier tire replace-
ment.
• Distance driven.
• Performance tires, tires with a speed rating of V or higher, and Summer tires typically
have a reduced tread life. Rotation of these
tires per the vehicle scheduled mainte-
nance is highly recommended.
WARNING!
Tires and the spare tire should be replaced
after six years, regardless of the remaining
tread. Failure to follow this warning can
result in sudden tire failure. You could lose
control and have a collision resulting in
serious injury or death.
Keep dismounted tires in a cool, dry place
with as little exposure to light as possible.
Protect tires from contact with oil, grease,
and gasoline.
Replacement Tires
The tires on your new vehicle provide a bal-
ance of many characteristics. They should be
inspected regularly for wear and correct cold
tire inflation pressures. The manufacturer
strongly recommends that you use tires
equivalent to the originals in size, quality and
performance when replacement is needed.
Refer to the paragraph on “Tread Wear Indi-
cators” in this section. Refer to the Tire and
Loading Information placard or the Vehicle
Certification Label for the size designation of
your tire. The Load Index and Speed Symbol
for your tire will be found on the original
equipment tire sidewall.
See the Tire Sizing Chart example found in
the “Tire Safety Information” section of this
manual for more information relating to the
Load Index and Speed Symbol of a tire.
It is recommended to replace the two front
tires or two rear tires as a pair. Replacing just
one tire can seriously affect your vehicle’s
handling. If you ever replace a wheel, make
sure that the wheel’s specifications match
those of the original wheels.

Snow Tires
Some areas of the country require the use of
snow tires during the Winter. Snow tires can
be identified by a “mountain/snowflake”
symbol on the tire sidewall.If you need snow tires,
select tires equivalent
in size and type to the
original equipment
tires. Use snow tires
only in sets of four;
failure to do so may
adversely affect the
safety and handling of your vehicle.
Snow tires generally have lower speed ratings
than what was originally equipped with your
vehicle and should not be operated at sus-
tained speeds over 75 mph (120 km/h). For
speeds above 75 mph (120 km/h) refer to
original equipment or an authorized tire
dealer for recommended safe operating
speeds, loading and cold tire inflation pres-
sures. While studded tires improve performance on
ice, skid and traction capability on wet or dry
surfaces may be poorer than that of non-
studded tires. Some states prohibit studded
tires; therefore, local laws should be checked
before using these tire types.
Spare Tires — If Equipped
For vehicles equipped with Tire Service Kit
instead of a spare tire, please refer to “Tire
Service Kit” in “In Case Of Emergency” in
the Owner’s Manual at www.mopar.com/
en-us/care/owners-manual.html (U.S. Resi-
dents) or www.owners.mopar.ca (Canadian
Residents) for further information.
CAUTION!
Because of the reduced ground clearance,
do not take your vehicle through an auto-
matic car wash with a compact or limited
use temporary spare installed. Damage to
the vehicle may result.
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 func-
tion 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 rota-
tion for your vehicle. If your vehicle has this
option, refer to an authorized tire dealer for
the recommended tire rotation pattern.
Compact Spare Tire — If Equipped
The compact spare is for temporary emer-
gency use only. You can identify if your ve-
hicle 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 de-
scriptions begin with the letter “T” or “S”
preceding the size designation. Example:
T145/80D18 103M.

Since this tire has limited tread life, the
original equipment tire should be repaired (or
replaced) and reinstalled 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 lim-
ited 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 con-
trol.
Collapsible Spare Tire — If Equipped
The collapsible spare is for temporary emer-
gency use only. You can identify if your ve-
hicle is equipped with a collapsible 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.
Collapsible spare tire description example:
165/80-17 101P.
Since this tire has limited tread life, the
original equipment tire should be repaired (or
replaced) and reinstalled on your vehicle at
the first opportunity.
Inflate collapsible tire only after the wheel is
properly installed to the vehicle. Inflate the
collapsible tire using the electric air pump
before lowering the vehicle.
Do not install a wheel cover or attempt to
mount a conventional tire on the collapsible
spare wheel, since the wheel is designed
specifically for the collapsible spare tire.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 lim-
ited tread life. When the tread is worn to

WARNING!
vehicle. Failure to do so could result in
loss of vehicle control.
Wheel And Wheel Trim Care
All wheels and wheel trim, especially alumi-
num and chrome plated wheels, should be
cleaned regularly using mild (neutral Ph)
soap and water to maintain their luster and to
prevent corrosion. Wash wheels with the
same soap solution recommended for the
body of the vehicle.
Your wheels are susceptible to deterioration
caused by salt, sodium chloride, magnesium
chloride, calcium chloride, etc., and other
road chemicals used to melt ice or control
dust on dirt roads. Use a soft cloth or sponge
and mild soap to wipe away promptly. Do not
use harsh chemicals or a stiff brush. They
can damage the wheel’s protective coating
that helps keep them from corroding and
tarnishing.
CAUTION!
Avoid products or automatic car washes
that use acidic solutions or strong alkaline
additives or harsh brushes. Many aftermar-
ket wheel cleaners and automatic car
washes may damage the wheel's protective
finish. Such damage is not covered by the
New Vehicle Limited Warranty. Only car
wash soap, Mopar Wheel Cleaner or
equivalent is recommended.
When cleaning extremely dirty wheels includ-
ing excessive brake dust, care must be taken
in the selection of tire and wheel cleaning
chemicals and equipment to prevent damage
to the wheels. Mopar Wheel Treatment or
Mopar Chrome Cleaner or their equivalent is
recommended or 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 products may damage the

NOTE:
When installing a spare tire (if equipped) as
part of a dual rear wheel end combination,
the tire diameter of the two individual tires
must be compared. If there is a significant
difference, the larger tire should be installed
in a front location. The correct direction of
rotation for dual tire installations must also
be observed.
These dual rear wheels should be tightened as
follows:It is recommended that wheel stud nuts be
kept torqued to specifications at all times.
Torque wheel stud nuts to specifications at
each lubrication interval.
