TIRES
Information about tire quality
grades
New vehicles are fitted with tires
that have their Tire Quality Grade
(described below) molded into the
tire's sidewall. These Tire Quality
Grades are determined by
standards that the United States
Department of Transportation has
set.
Tire Quality Grades apply to new
pneumatic tires for use on
passenger cars. They do not apply
to deep tread, winter-type snow
tires, space-saver or temporary use
spare 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 Ford 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 grade 150
would wear one and one-half (1
1/2) times as well on the
government course as a tire grade
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 A B C
The traction grades, from highest
to lowest are A, B, and C, and they
represent the tire's ability to stop
on wet pavement as measured
under 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
braking (straightahead) traction
tests and does not include
cornering (turning) traction.
Temperature A B C
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
com_treadwear.01
com_traction_abc.01
com_temperature_abc.01
Maintenance and care
183

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. 109. Grades B and A
represent higher levels of
performance on the laboratory test
wheel than the minimum required
by law.
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.
Servicing the tires
Checking the tire pressure
Check the tire pressure at least
once a month or after rotating
tires and inflate tires as necessary.
Tire pressure is most accurate
when tires are cold (after vehicle
has been parked for at least one
f12_servicing_tires
Maintenance and care
184

hour or driven less than 5 km [3
miles]).
The cold pressure amount is listed
on the Safety Compliance
Certification Label located on the
inside driver door latch pillar.
Improperly inflated tires
can affect vehicle handling
and can fail suddenly, possibly
resulting in loss of vehicle
control.
Rotating the tires
Rotate your tires at regular
intervals to ensure even wear.
Refer to the following diagrams for
rotation cycles. Rotation intervals
are listed in the ªService Guide.º
Your wheels and tires are
match-mounted for improved ride.
Before you begin a tire repair,
mark the wheel and tire to ensure

Maintenance and care
185

proper alignment when
remounting.
²Four-tire rotation
²Five-tire rotation
Replacing the tires
Replace the tires when the wear
band is visible through the tire
treads.

Maintenance and care
186

When replacing full size
tires, never mix radial,
bias-belted, or bias-type tires.
Use only the tire sizes that are
listed on the tire pressure decal.
Make sure that all tires are the
same size, speed rating, and
load-carrying capacity. Use only
the tire combinations
recommended on the decal. If
you do not follow these
precautions, your vehicle may
not drive properly and safely.
Make sure that all
replacement tires are of
the same size, type, load-carrying
capacity and tread design (e.g.,
ªAll Terrainº, etc.), as originally
offered by Ford.
Do not replace your tires
with ªhigh performanceª
tires or larger size tires.
Failure to follow these
precautions may adversely
affect the handling of the vehicle
and make it easier to lose control
and roll over.
Identifying tire types
Refer to the Safety Compliance
Certification Label to determine
the specific size tire and wheel
Ford Motor Company recommends
for use on this vehicle.

Snow tires and chains
Snow tires must be the
same size and grade as the
tires you currently have on your
vehicle.
The tires on your vehicle have all
weather treads to provide traction
in rain and snow.
However, in some climates, you
may need to use snow tires and
chains.
Follow these guidelines when using
snow tires and chains.
²Use only SAE Class ªSº chains.
²Install chains securely, verifying
that the chains do not touch any
wiring, brake lines or fuel lines.
²4x2: Install tire chains on rear
tires (of all sizes) only.
²4x4: Install tire chains on rear
tires (of all sizes), and on front
tires of size P235/70R16 only.
²Drive cautiously. If you hear the
chains rub or bang against your
vehicle, stop and retighten the
chains. If this does not work,
remove the chains to prevent
damage to your vehicle.
²If possible, avoid fully loading
your vehicle.
²Remove the tire chains when
they are no longer needed. Do
not use tire chains on dry roads.
²The suspension insulation and
bumpers will help prevent
vehicle damage. Do not remove

these components from your
vehicle when using snow tires
and chains.
FUEL
Important safety precautions
Do not overfill the fuel
tank. The pressure in an
overfilled tank may cause
leakage and lead to fuel spray
and fire.
If you do not use the
proper fuel cap, the
pressure in the fuel tank can
damage the fuel system or cause
it to work improperly in a
collision.
The fuel system may be
under pressure. If the fuel
cap is venting vapor or if you
hear a hissing sound, wait until it
stops before completely
removing the cap.
Automotive fuels can
cause serious injury or
death if misused or mishandled.
