GENERAL INFORMATION
Use only approved wheel and tire sizes,
using other sizes could damage your vehicle.
If you change the diameter of the tires from
that fitted at the factory, the speedometer
may not display the correct speed. If you
intend to change the size of the wheels from
that fitted by the manufacturer, you can
check the suitability with an authorized
dealer.
Additional information related to the
functionality and maintenance of your tires
can be found later in this chapter. See Tire
Care (page 409).
You can find the recommended tire inflation
pressures can on the Tire Label, which is on
the B-pillar or the edge of the driver door.
You can also find this information on the
Safety Compliance Certification Label, affixed
to either the door hinge pillar, door-latch
post, or the door edge that meets the door
latch post; next to the driver seating position. We strongly recommend maintaining these
tire pressures at all times. Failure to follow
the tire pressure recommendations can
cause uneven treadwear patterns, reduced
fuel economy, and adversely affect the way
your vehicle handles.
Note:
Check and set the tire pressure at the
ambient temperature in which you are
intending to drive your vehicle and when the
tires are cold.
Note: Check your tire pressures at least once
per month.
If your vehicle has a spare tire, set the
pressure to the highest value given for your
vehicle and tire size combination.
Notice to utility vehicle and truck
owners WARNING:
Utility vehicles have a
significantly higher rollover rate than other
types of vehicles. WARNING:
Vehicles with a higher
center of gravity (utility and four-wheel
drive vehicles) handle differently than
vehicles with a lower center of gravity
(passenger cars). Avoid sharp turns,
excessive speed and abrupt steering in
these vehicles. Failure to drive cautiously
increases the risk of losing control of your
vehicle, vehicle rollover, personal injury
and death. WARNING:
In a rollover crash, an
unbelted person is significantly more likely
to die than a person wearing a seatbelt. WARNING:
Do not become
overconfident in the ability of four-wheel
drive vehicles. Although a four-wheel drive
vehicle may accelerate better than a
two-wheel drive vehicle in low traction
situations, it won't stop any faster than
two-wheel drive vehicles. Always drive at
a safe speed.

Utility vehicles and trucks handle differently
than passenger cars in the various driving
conditions that are encountered on streets,
highways and off-road. Utility vehicles and
trucks are not designed for cornering at
speeds as high as passenger cars any more
than low-slung sports cars are designed to
perform satisfactorily under off-road
conditions.
Study your owner's manual and any
supplements for specific information about
equipment features, instructions for safe
driving and additional precautions to reduce
the risk of an accident or serious injury.
Four-wheel drive system (If Equipped)
WARNING:
Do not become
overconfident in the ability of four-wheel
drive vehicles. Although a four-wheel drive
vehicle may accelerate better than a
two-wheel drive vehicle in low traction
situations, it won't stop any faster than
two-wheel drive vehicles. Always drive at
a safe speed. A vehicle equipped with four-wheel drive,
when selected, has the ability to use all four
wheels to power itself. This increases traction
which may enable you to safely drive over
terrain and road conditions that a
conventional two-wheel drive vehicle cannot.
Power is supplied to all four wheels through
a transfer case or power transfer unit.
Four-wheel drive vehicles allow you to select
different modes as necessary. For
information on transfer case operation and
shifting procedures, See Four-Wheel Drive
(page 233). For information on transfer case
maintenance,
See Maintenance (page 377).
You should become thoroughly familiar with
this information before you operate your
vehicle.
On some four-wheel drive vehicles, the initial
shift from two-wheel to four-wheel drive
when the vehicle is moving can cause a
momentary clunk and ratcheting sound.
These sounds are normal and are not cause
for concern. In four-wheel drive vehicles, the size of the
spare tire relative to the remaining tires can
have an effect on the 4x4 system. If there is
a significant difference between the size of
a spare and the remaining tires, four-wheel
drive functionality may be limited. See Using
Four-Wheel Drive
(page 233).
How your vehicle differs from other
vehicles
Sport utility vehicles and trucks can differ
from some other vehicles in a few noticeable
ways. Your vehicle may be:
408
Navigator (TB9) Canada/United States of America, enUSA, First-Printing Wheels and Tires

•
Higher - to allow higher load carrying
capacity and to allow it to travel over
rough terrain without getting hung up or
damaging underbody components.
• Shorter - to give it the capability to
approach inclines and drive over the
crest of a hill without getting hung up or
damaging underbody components. All
other things held equal, a shorter
wheelbase may make your vehicle
quicker to respond to steering inputs
than a vehicle with a longer wheelbase.
• Narrower - to provide greater
maneuverability in tight spaces,
particularly in off-road use.
As a result of the above dimensional
differences, Sport utility vehicles and trucks
often have a higher center of gravity and a
greater difference in center of gravity
between the loaded and unloaded condition.
These differences that make your vehicle so
versatile also make it handle differently than
an ordinary passenger car. TIRE CARE
Information About Uniform Tire Quality
Grading
Tire Quality Grades apply to new
pneumatic passenger car tires. The
Quality grades can be found where
applicable on the tire sidewall between
tread shoulder and maximum section
width. For example: Treadwear 200
Traction AA Temperature A. These Tire Quality Grades are
determined by standards that the United
States Department of Transportation has
set.
Tire Quality Grades apply to new
pneumatic passenger car tires. They do
not apply to deep tread, winter-type
snow tires, space-saver or temporary
use spare tires, light truck or LT type
tires, tires with nominal rim diameters of
10 to 12 inches or limited production tires
as defined in Title 49 Code of Federal
Regulations Part 575.104 (c)(2).
U.S. Department of Transportation Tire
quality grades: The U.S. Department of
Transportation requires us to give you
the following information about tire
grades exactly as the government has
written it.

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 (1 ½) 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 AA A B C
WARNING: The traction grade
assigned to this tire is based on
straight-ahead braking traction tests,
and does not include acceleration,
cornering, hydroplaning or peak
traction characteristics. The traction grades, from highest to
lowest are AA, A, B, and C. The 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.
Temperature A B C WARNING:
The temperature
grade for this tire is established for a
tire that is properly inflated and not
overloaded. Excessive speed,
underinflation, or excessive loading,
either separately or in combination,
can cause heat buildup and possible
tire failure.
The temperature grades are A (the
highest), B and C, representing the tire ’s
resistance to the generation of heat and
its ability to dissipate heat when tested
under controlled conditions on a
specified indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to degenerate
and reduce tire life, and excessive
temperature can lead to sudden tire
failure. The grade C corresponds to a
level of performance which all
passenger car tires must meet under the
Federal Motor Vehicle Safety Standard
No. 139. Grades B and A represent
higher levels of performance on the
laboratory test wheel than the minimum
required by law.
Glossary of Tire Terminology

Information on P Type Tires
P215/65R15 95H is an example of a tire
size, load index and speed rating. The
definitions of these items are listed
below. (Note that the tire size, load index
and speed rating for your vehicle may
be different from this example.) A. P: Indicates a tire, designated by the
Tire and Rim Association, that may be
used for service on cars, sport utility
vehicles, minivans and light trucks.
Note:
If your tire size does not begin with a
letter this may mean it is designated by
either the European Tire and Rim
Technical Organization or the Japan Tire
Manufacturing Association.
B.
215: Indicates the nominal width of
the tire in millimeters from sidewall edge
to sidewall edge. In general, the larger
the number, the wider the tire.
C.
65: Indicates the aspect ratio which
gives the tire's ratio of height to width.
D.
R: Indicates a radial type tire.
E.
15: Indicates the wheel or rim
diameter in inches. If you change your
wheel size, you will have to purchase
new tires to match the new wheel
diameter. F.
95: Indicates the tire's load index. It
is an index that relates to how much
weight a tire can carry. You may find this
information in your owner’ s manual. If
not, contact a local tire dealer.
Note: You may not find this information
on all tires because it is not required by
federal law.
G.
H: Indicates the tire's speed rating.
The speed rating denotes the speed at
which a tire is designed to be driven for
extended periods of time under a
standard condition of load and inflation
pressure. The tires on your vehicle may
operate at different conditions for load
and inflation pressure. These speed
ratings may need to be adjusted for the
difference in conditions. The ratings
range from
81 mph (130 km/h) to
186 mph (299 km/h). These ratings are
listed in the following chart.
Note: You may not find this information
on all tires because it is not required by
federal law.
