TIRE CARE
Information About Uniform Tire Quality Grading
Tire Quality Grades apply to new
pneumatic passenger car tires. The Tire
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 Ford Motor Company 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 1
1 2times 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.

INFORMATION CONTAINED ON THE TIRE SIDEWALL
Both U.S. and Canada Federal regulations require 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.)
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.

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. Tire Quality Grades
do not apply to this type of tire.
A.T:Indicates a type of tire, designated by the Tire and Rim
Association, that is intended for temporary service on cars, sport-utility
vehicles, minivans and light trucks.
B.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.
C.80:Indicates the aspect ratio, which gives the tire’s ratio of height to
width. Numbers of 70 or lower indicate a short sidewall.
D.D:Indicates a diagonal type tire.R:Indicates a radial type tire.
E.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. See the payload description and graphic in theLoad
Carryingchapter.
