Radial Ply Tires
Warning!
Combining radial ply tires with other types
of tires on your vehicle will cause your
vehicle to handle poorly. The instability could
cause a collision. Always use radial ply tires
in sets of four. Never combine them with
other types of tires.
Tire Repair
If your tire becomes damaged, it may be
repaired if it meets the following criteria:
The tire has not been driven on when
flat.
The damage is only on the tread
section of your tire (sidewall damage is
not repairable).
The puncture is no greater than a ¼ of
an inch (6 mm).
Consult an authorized tire dealer for tire
repairs and additional information.
Damaged Run Flat tires, or Run Flat tires
that have experienced a loss of pressure
should be replaced immediately with
another Run Flat tire of identical size and
service description (Load Index and
Speed Symbol).
Run Flat Tires — If Equipped
Run Flat tires allow you the capability to
drive 50 miles (80 km) at 50 mph
(80 km/h) after a rapid loss of inflation
pressure. This rapid loss of inflation is referred to as the Run Flat mode. A Run
Flat mode occurs when the tire inflation
pressure is of/or below 14 psi (96 kPa).
Once a Run Flat tire reaches the run flat
mode it has limited driving capabilities
and needs to be replaced immediately. A
Run Flat tire is not repairable.
It is not recommended driving a vehicle
loaded at full capacity or to tow a trailer
while a tire is in the run flat mode.
See the tire pressure monitoring section
for more information.
Tire Spinning
When stuck in mud, sand, snow, or ice
conditions, do not spin your vehicle's
wheels above 30 mph (48 km/h) or for
longer than 30 seconds continuously
without stopping.
235

Warning!
Fast spinning tires can be dangerous. Forces
generated by excessive wheel speeds may
cause tire damage or failure. A tire could
explode and injure someone. Do not spin
your vehicle's wheels faster than 30 mph
(48 km/h) for more than 30 seconds
continuously when you are stuck, and do not
let anyone near a spinning wheel, no matter
what the speed.
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 willappear 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 abnormal wear patterns will
reduce tread life, resulting in the need for
earlier tire replacement.
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
maintenance 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
balance 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 Indicators” 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.
It is recommended you contact an
authorized tire dealer or original

SERVICING AND MAINTENANCE

equipment dealer with any questions you
may have on tire specifications or
capability. Failure to use equivalent
replacement tires may adversely affect
the safety, handling, and ride of your
vehicle.
Warning!
Do not use a tire, wheel size, load rating,
or speed rating other than that specified for
your vehicle. Some combinations of
unapproved tires and wheels may change
suspension dimensions and performance
characteristics, resulting in changes to
steering, handling, and braking of your
vehicle. This can cause unpredictable
handling and stress to steering and
suspension components. You could lose
control and have a collision resulting in
serious injury or death. Use only the tire and
wheel sizes with load ratings approved for
your vehicle.
Never use a tire with a smaller load index
or capacity, other than what was originally
equipped on your vehicle. Using a tire with a
smaller load index could result in tire
overloading and failure. You could lose
control and have a collision.
Failure to equip your vehicle with tires
having adequate speed capability can result
in sudden tire failure and loss of vehicle
control.
Caution!
Replacing original tires with tires of a
different size may result in false
speedometer and odometer readings.
Spare Tires — If Equipped
Note: For vehicles equipped with Tire
Service Kit instead of a spare tire, please
refer to “Tire Service Kit” in “In Case Of
Emergency” for further information.
Caution!
Because of the reduced ground clearance,
do not take your vehicle through an
automatic 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 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
recommended 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.
Example: T145/80D18 103M.
T, S = Temporary Spare Tire
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.
237

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.
Full Size Spare — If Equipped
The full size spare is for temporary
emergency use only. This tire may look
like the originally equipped tire on the
front or rear axle of your vehicle, but it is
not. This spare tire may have limited
tread life. When the tread is worn to the
tread wear indicators, the temporary use
full size spare tire needs to be replaced.
Since it is not the same as your original
equipment tire, replace (or repair) the
original equipment tire and reinstall on
the vehicle at the first opportunity.
Limited Use Spare — If Equipped
The limited use spare tire is for
temporary emergency use only. This tire
is identified by a label located on the
limited use spare wheel. This label
contains the driving limitations for this
spare. This tire may look like the originalequipped tire on the front or rear axle of
your vehicle, but it is not. Installation of
this limited use spare tire affects vehicle
handling. Since it is not the same as your
original equipment tire, replace (or
repair) the original equipment tire and
reinstall on the vehicle at the first
opportunity.
Warning!
Limited use spares are for emergency use
only. Installation of this limited use spare
tire affects vehicle handling. With this tire,
do not drive more than the speed listed on
the limited use spare wheel. Keep inflated to
the cold tire inflation pressures listed on
your Tire and Loading Information Placard
located on the driver’s side B-Pillar or the
rear edge of the driver’s side door. Replace
(or repair) the original equipment tire at the
first opportunity and reinstall it on your
vehicle. Failure to do so could result in loss of
vehicle control.
Wheel And Wheel Trim Care
All wheels and wheel trim, especially
aluminum 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
and remember to always wash when the
surfaces are not hot to the touch.
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
aftermarket 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
including 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.
238
SERVICING AND MAINTENANCE

Caution!
Do not use scouring pads, steel wool, a
bristle brush, metal polishes or oven cleaner.
These products 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.
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 components. This activity will
remove the red rust on the brake rotors
and prevent vehicle vibration when
braking.
Dark Vapor Chrome, Black Satin
Chrome, or Low Gloss Clear Coat Wheels
Caution!
If your vehicle is equipped with these
specialty wheels, DO NOT USE wheel
cleaners, abrasives, or polishing compounds.
They will permanently damage 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 Types
All Season Tires — If Equipped
All Season tires provide traction for all
seasons (Spring, Summer, Fall, and
Winter). Traction levels may vary
between different all season tires. All
season tires can be identified by the M+S,
M&S, M/S or MS designation on the tire
sidewall. Use all season tires only in sets
of four; failure to do so may adversely
affect the safety and handling of your
vehicle.
Summer Or Three Season Tires — If
Equipped
Summer tires provide traction in both
wet and dry conditions, and are not
intended to be driven in snow or on ice. If
your vehicle is equipped with Summer
tires, be aware these tires are not
designed for Winter or cold driving
conditions. Install Winter tires on your
vehicle when ambient temperatures are
less than 45°F (7°C) or if roads are
covered with ice or snow. For more
information, contact an authorized
dealer.
Summer tires do not contain the all
season designation or mountain/
snowflake symbol on the tire sidewall.
Use Summer tires only in sets of four;
failure to do so may adversely affect the
safety and handling of your vehicle.
Warning!
Do not use Summer tires in snow/ice
conditions. You could lose vehicle control,
resulting in severe injury or death. Driving
too fast for conditions also creates the
possibility of loss of vehicle control.
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 sustained 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 pressures.
239

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.
Tire Chains (Traction Devices)
Use of traction devices require sufficient
tire-to-body clearance. Follow these
recommendations to guard against
damage.
Note:
Traction device must be of proper
size for the tire, as recommended by the
traction device manufacturer
Use on Rear Tires Only
Due to limited clearance, the
following traction devices are
recommended:
For a 285/40R20 tire, use of a
zero-clearance snow traction device
recommended.
Caution!
To avoid damage to your vehicle or tires,
observe the following precautions:
Because of restricted traction device
clearance between tires and other
suspension components, it is important that
only traction devices in good condition are
used. Broken devices can cause serious
damage. Stop the vehicle immediately if
noise occurs that could indicate device
breakage. Remove the damaged parts of
the device before further use.
Install device as tightly as possible and
then retighten after driving about ½ mile
(0.8 km).
Do not exceed 30 mph (48 km/h).
Drive cautiously and avoid severe turns
and large bumps, especially with a loaded
vehicle.
Do not drive for a prolonged period on dry
pavement.
Observe the traction device
manufacturer’s instructions on the method
of installation, operating speed, and
conditions for use. Always use the
suggested operating speed of the device
manufacturer’s if it is less than 30 mph
(48 km/h).
Do not use traction devices on a compact
spare tire.
Tire Rotation Recommendations
Tire Rotations - Do Not Rotate Tires
Due to different size tires and wheels on
front and rear axles tire rotation is not
possible.
Caution!
Damage to the vehicle may occur if front
and rear tires are rotated
In the case of irregular wear of the tires
identify the cause and correct it as soon
as possible, by contacting an authorized
dealer.
