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
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.
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 Indica-
tors” 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
TIRES
17

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!
•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 perfor-
mance characteristics, resulting in changes to steering, handling,
and braking of your vehicle. This can cause unpredictable han-
dling 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.

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 40°F (5°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
TIRES
19

authorized tire dealer for recommended safe operating speeds, loading
and cold tire inflation pressures.
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
NOTE:For vehicles equipped with Tire Service Kit instead of a spare tire,
please refer to “Tire Service Kit” in “In Case Of Emergency” in your
Owner ’s Manual 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
TIRES
20

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 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 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
original equipped 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

DEPARTMENT OF TRANSPORTATION UNIFORM
TIRE QUALITY GRADES
The following tire grading categories were established by the Na-
tional Highway Traffic Safety Administration. The specific grade
rating assigned by the tire’s manufacturer in each category is shown
on the sidewall of the tires on your vehicle.
All passenger vehicle tires must conform to Federal safety require-
ments 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 characteristics 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 controlled conditions on specified government test
surfaces of asphalt and concrete. A tire marked C may have poor
traction performance.
WARNING!
The traction grade assigned to this tire is based on straight-ahead
braking traction tests, and does not include acceleration, corner-
ing, hydroplaning, or peak traction characteristics.
