2015 FORD TRANSIT wheel

As a result of the above dimensional
differences, sport-utility vehicles, vans and
trucks often will 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 Grades 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.
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).
Tire Quality Grades are
determined by standards that the
United States Department of
Transportation has set.
United States Department of
Transportation Tire Quality
Grades
The United States of America
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 1½ times as well on
the government course as a tire
234 Transit (TTH) Canada/United States of America, enUSA, Edition date: 03/2014 Wheels and TiresE166373 E142542

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 correctly inflated and
not overloaded. Excessive speed,
under-inflation, 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
• Tire label: A label showing the
OE (Original Equipment) tire
sizes, recommended inflation
pressure and the maximum
weight the vehicle can carry.
• Tire Identification Number
(TIN): A number on the
sidewall of each tire providing
information about the tire
brand and manufacturing
plant, tire size and date of
manufacture. Also referred to
as DOT code.
• Inflation pressure: A measure

•
Standard load: A class of
P-metric or Metric tires
designed to carry a maximum
load at set pressure. For
example: for P-metric tires
35 psi (2.4 bar)
or 36 psi
(2.5 bar) depending on tire size
and for Metric tires
36 psi
(2.5 bar). Increasing the
inflation pressure beyond this
pressure will not increase the
tire capability.
• Extra load: A class of P-metric
or Me

tric tires designed to carry
a heavier maximum load at
42 psi (2.9 bar). Increasing the
inflation pressure beyond this
pressure will not increase the
tire ’s load carrying capability.
• bar Metric unit of atmospheric
pressure.
• kPa:
Kilopascal, a metric unit
of air pressure.
• PSI:
Pounds per square inch, a
standard unit of air pressure.
• Cold tire pressure:
The tire
pressure when the vehicle has
been stationary and out of
direct sunlight for an hour or
more and prior to the vehicle
being driven for 1 mi (1.6 km). •
Recommended inflation
pressure:
The cold inflation
pressure found 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) or Tire
Label located on the B-Pillar or
the edge of the driver door.
• B-pillar: The structural
member at the side of the
vehicle behind the front door.
• Bead area of the tire: Area of
the tire next to the rim.
• Sidewall of the tire:
Area
between the bead area and the
tread.
• Tread area of the tire: Area of
the perimeter of the tire that
contacts the road when
mounted on the vehicle.
• Rim: The metal support
(wheel) for a tire or a tire and
tube assembly upon which the
tire beads are seated.
Information Contained on the
Tire Sidewall
United States of America, and
Canada Federal regulations
require tire manufacturers to place
standardized information on the
sidewall of all tires. This
information identifies and

Treadwear, Traction
and Temperature
Grades:Treadwear The
treadwear grade is a
comparative rating based
on the wear rate of the tire
L
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. Traction:
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:
The
temperature grades are A
(the highest), B and C,
representing the tire's
resistance to the
