INFORMATION ABOUT UNIFORM TIRE QUALITY GRADING
New vehicles are fitted with tires
that have a rating on them called
Tire Quality Grades. 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 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 graded 150 would wear one
and one-half (1 1/2) 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
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.

INFORMATION CONTAINED ON THE TIRE SIDEWALL
Federal law requires tire manufacturers to place standardized
information on the sidewall of all tires. This information identifies and
describes the fundamental characteristics of the tire and also provides a
U.S. DOT Tire Identification Number for safety standard certification and
in case of a recall.
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.)
1.P: Indicates a tire, designated by
the Tire and Rim Association
(T&RA), that may be used for
service on cars, SUVs, minivans and
light trucks.
Note: If your tire size does not
begin with a letter this may mean it
is designated by either ETRTO
(European Tire and Rim Technical Organization) or JATMA (Japan Tire
Manufacturing Association).
2. 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.
3. 65: Indicates the aspect ratio which gives the tire ’s ratio of height to
width.
4. R: Indicates a “radial ”type tire.
5. 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.
6. 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 Guide. 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.

Information on“T ” type tires
“ T ” type tires have some additional
information beyond those of “P ”
type tires; these differences are
described below:
T145/80D16 is an example of a tire
size.
Note: The temporary tire size for
your vehicle may be different from
this example.
1. T: Indicates a type of tire,
designated by the Tire and Rim
Association (T&RA), that is
intended for temporary service on
cars, SUVs, minivans and light
trucks.
2. 145: 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.
3. 80: Indicates the aspect ratio which gives the tire ’s ratio of height to
width. Numbers of 70 or lower indicate a short sidewall.
4. D: Indicates a “diagonal ”type tire.
R: Indicates a “radial ”type tire.
5. 16: 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.
Location of the tire label
You will find a tire label containing tire inflation pressure by tire size and
other important information located on the B-Pillar or the edge of the
driver ’s door.
TIRE CARE
Improper or inadequate vehicle maintenance can also cause tires to wear
abnormally. Here are some of the important maintenance items:
Tire wear
Measure and inspect the tire tread on all your tires periodically.
Advanced and unusual tire wear can reduce the ability of tread to grip

Wheels
Your Ford GT is equipped with unique wheels matched to the tires.
These wheels are more susceptible to damage due to their diameter,
width and low profile tires. To avoid damage to your wheels:
•Maintain proper tire pressure (see “Tires ”previously listed).
• When installing wheels, always torque lug nuts to specification with a
torque wrench.
• Inspect your wheels for damage on a regular basis. If a wheel is
damaged, replace it immediately.
• In the event that you encounter an abnormally harsh impact, inspect
the outer diameter of your wheels, both inside and out, for damage
Operating a performance vehicle at higher than normal speeds
Your Ford GT is capable of operating at higher than normal speeds and is
equipped with tires rated for the vehicles ’maximum speed. However, it
is important to remember to always drive safely, obey all traffic laws and
only operate your Ford GT at higher than normal speeds at locations and
under conditions where such can be done safely. Also, before operating
your vehicle at higher than normal speeds:
• Maintain your tire pressures according to the tire information and high
speed warning labels located on the B-pillar or the edge of the driver ’s
door.
• Inspect wheels and tires for wear and damage. Replace any damaged
wheels or tires.
Winter driving
The original equipment tires on your Ford GT are designed for maximum
performance in dry and wet conditions. They are not designed for winter
use on ice or snow and cannot be used with snow chains or other tire
mounted traction aids.
Tire and wheel alignment
A bad jolt from hitting a curb or pothole can cause the front end of your
vehicle to become misaligned or cause damage to your tires. If your
vehicle seems to pull to one side when you ’re driving, the wheels may be
out of alignment. Have a qualified technician at a Ford or
Lincoln/Mercury dealer check the wheel alignment periodically.

WASHING THE EXTERIOR
Wash your vehicle regularly with cool or lukewarm water and a neutral
Ph shampoo, such as Motorcraft Detail Wash (ZC-3–A), which is available
from your dealer.
• Do not drive your vehicle through an automated, commercial
car wash due to the vehicle ’s low ground clearance, tire width
and track. Wash your vehicle by hand, with a commercial wand,
or by using a touchless commercial wash with no mechanical
tracks on the floor.
• Never use strong household detergents or soap, such as dish washing
or laundry liquid. These products can discolor and spot painted
surfaces.
• Never wash a vehicle that is “hot to the touch ”or during exposure to
strong, direct sunlight.
• Always use a clean sponge or car wash mitt with plenty of water for
best results.
• Dry the vehicle with a chamois or soft terry cloth towel in order to
eliminate water spotting.
• It is especially important to wash the vehicle regularly during the
winter months, as dirt and road salt are difficult to remove and cause
damage to the vehicle.
• Immediately remove items such as gasoline, diesel fuel, bird droppings
and insect deposits because they can cause damage to the vehicle ’s
paintwork and trim over time.
• Suntan lotions and insect repellents can damage any painted
surface; if these substances come in contact with your vehicle,
wash off as soon as possible.
