WARNING!
Overloading of your tires is dangerous. Overloading
can cause tire failure, affect vehicle handling, and
increase your stopping distance. Use tires of the rec-
ommended load capacity for your vehicle. Never over-
load them.

Tires — General Information
Tire Pressure
Proper tire inflation pressure is essential to the safe and
satisfactory operation of your vehicle. Four primary areas
are affected by improper tire pressure:
•Safety and Vehicle Stability
• Economy
• Tread Wear
• Ride Comfort
Safety

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 informa-
tion.
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.Refer to “Freeing A Stuck Vehicle” in “In Case Of Emer-
gency” for further information.

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 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.

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 manu-
facturer 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 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!(Continued)
•Failure to equip your vehicle with tires having ad-
equate speed capability can result in sudden tire
failure and loss of vehicle control.

Tire Chains (Traction Devices)
Use of traction devices require sufficient tire-to-body clear-
ance. Follow these recommendations to guard against
damage.
•Traction device must be of proper size for the tire, as
recommended by the traction device manufacturer
• Use on Front Tires Only
• Due to limited clearance, the following traction devices
are recommended:
Front Wheel Drive (FWD) Models
• Original equipment 225/60R17 and 225/55R18 tire sizes
are not chainable.
• The use of 7 mm snow chains is permitted with the use
of 215/60R17 tires on size 17 x 7.0 ET41 wheels.
Four Wheel Drive (4WD) Non-Trailhawk Models without
a Two-Speed Power Takeoff Unit
• Original equipment 225/65R17 and 225/60R18 tire sizes
are not chainable.
• The use of 9 mm snow chains is permitted with the use
of 215/60R17 tires on size 17 x 7.0 ET41 wheels. Four Wheel Drive (4WD) Non-Trailhawk Models with a
Two-Speed Power Takeoff Unit
•
The use of 7 mm snow chains is permitted with 225/
65R17 and 225/60R18 tires.
Four Wheel Drive (4WD) Trailhawk Models
• The use of 9 mm snow chains is permitted with the use
of 225/65R17 tires on size 17 x 7.5 ET31 wheels.

TIRE QUALITY GRADES
The following tire grading categories were established
by the National Highway Traffic Safety Administration.
The specific grade rating assigned by the tire’s manu-
facturer in each category is shown on the sidewall of the
tires on your vehicle.
All passenger vehicle tires must conform to Federal
safety requirements in addition to these grades.
Treadwear
The Treadwear grade is a comparative rating, based on
the wear rate of the tire when tested under controlled
conditions on a specified government test course. For
example, a tire graded 150 would wear one and one-half
times as well on the government course as a tire graded
100. The relative performance of tires depends upon the
actual conditions of their use, however, and may depart
significantly from the norm due to variations in driving
habits, service practices, and differences in road charac-
teristics and climate.
Traction Grades
The Traction grades, from highest to lowest, are AA, A,
B, and C. These grades represent the tire’s ability to
stop on wet pavement, as measured under controlledconditions on specified government test surfaces of
asphalt and concrete. A tire marked C may have poor
traction performance.

WARNING!
The temperature grade for this tire is established for
a tire that is properly inflated and not overloaded.
Excessive speed, under-inflation, or excessive load-
ing, either separately or in combination, can cause
heat buildup and possible tire failure.
STORING THE VEHICLE
If the vehicle should remain stationary for more than a
month, observe the following precautions:
• Park your vehicle in a covered, dry and possibly airy
location the windows open slightly.
• Check that the Electric Park Brake is not engaged.
• Disconnect the negative (-) terminal from the battery
post and be sure that the battery is fully charged. During
storage check battery charge quarterly.
• If you do not disconnect the battery from the electrical
system, check the battery charge every 30 days.
• Clean and protect the painted parts by applying protec-
tive waxes. •
Clean and protect polished metal parts by applying
protective waxes.
• Apply talcum powder to the front and rear wiper blades
and leave raised from the glass.
• Cover the vehicle with an appropriate cover taking care
not to damage the painted surface by dragging across
dirty surfaces. Do not use plastic sheeting which will not
allow the evaporation of moisture present on the surface
of the vehicle.
• Inflate the tires at a pressure of +7.25 psi (+0.5 bar)
higher than recommended on the tire placard and check
it periodically.
• Do not drain the engine cooling system.
• Whenever you leave the vehicle is stationary for two
weeks or more, run idle the engine for approximately
five minutes, with the air conditioning system on and
high fan speed. This will ensure a proper lubrication of
the system, thus minimizing the possibility of damage to
the compressor when the vehicle is put back into opera-
tion.
