•Narrower – to provide greater
maneuverability in tight spaces,
particularly in off-road use.
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 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.

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 of the amount of air in a tire.
•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 (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 Metric 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.
•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 mile (1.6 kilometers).
•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’s seating position) or Tire Label
located on the B-Pillar or the edge of the driver’s 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.

M.Maximum Inflation Pressure:Indicates the tire manufacturer’s
maximum permissible pressure or the pressure at which the maximum
load can be carried by the tire. This pressure is normally higher than the
vehicle manufacturer’s recommended cold inflation pressure, which can
be 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’s seating position), or Tire Label which
is located on the B-Pillar or the edge of the driver’s door. The cold
inflation pressure should never be set lower than the recommended
pressure on the vehicle label.
The tire suppliers may have additional markings, notes or warnings, such
as standard load or radial tubeless.
Additional Information Contained on the Tire Sidewall for LT Type

telltale after replacing one or more tires or wheels on your vehicle to
ensure that the replacement or alternate tires and wheels allow the
TPMS to continue to function properly.
The tire pressure monitoring system complies with part 15 of the FCC
rules and with RSS-210 of Industry Canada. Operation is subject to the
following two conditions: (1) This device may not cause harmful
interference, and (2) This device must accept any interference received,
including interference that may cause undesired operation.
Changing Tires with a Tire Pressure Monitoring System
Note:Each road tire is equipped
with a tire pressure sensor located
inside the tire and wheel assembly
cavity. The pressure sensor is
attached to the valve stem. The
pressure sensor is covered by the
tire and is not visible unless the tire
is removed. Take care when
changing the tire to avoid damaging
the sensor.
You should always have your tires serviced by an authorized dealer.
Check the tire pressure periodically (at least monthly) using an accurate
tire gauge. SeeInflating Your Tiresin this chapter.
Understanding Your Tire Pressure Monitoring System
The tire pressure monitoring system measures pressure in your four road
tires and sends the tire pressure readings to your vehicle. The low tire
pressure warning light will turn on if the tire pressure is significantly low.
Once the light is illuminated, your tires are under-inflated and need to be
inflated to the manufacturer’s recommended tire pressure. Even if the
light turns on and a short time later turns off, your tire pressure still
needs to be checked.
When your spare tire is installed
When one of your road tires needs to be replaced with the spare, the tire
pressure monitoring system will continue to identify an issue to remind
you that the damaged road wheel or tire needs to be repaired and put
back on your vehicle.
To restore the full function of the tire pressure monitoring system, have
the damaged road wheel or tire repaired and remounted on your vehicle.
For additional information, seeChanging Tires with a Tire Pressure
Monitoring Systemin this section.

When you believe your system is not operating properly
The main function of the tire pressure monitoring system is to warn you
when your tires need air. It can also warn you in the event the system is
no longer capable of functioning as intended. See the following chart for

When inflating your tires
When putting air into your tires (such as at a gas station or in your
garage), the tire pressure monitoring system may not respond
immediately to the air added to your tires.
It may take up to two minutes of driving over 20 mph (32 km/h) for the
light to turn off after you have filled your tires to the recommended
inflation pressure.
How temperature affects your tire pressure
The tire pressure monitoring system monitors tire pressure in each
pneumatic tire. While driving in a normal manner, a typical passenger
tire inflation pressure may increase approximately 2 to 4 psi (14 to
28 kPa) from a cold start situation. If the vehicle is stationary overnight
with the outside temperature significantly lower than the daytime
temperature, the tire pressure may decrease approximately 3 psi
(21 kPa) for a drop of 30°F (17°C) in ambient temperature. This lower
pressure value may be detected by the system as being significantly
lower than the recommended inflation pressure and activate the system
warning light for low tire pressure. If the low tire pressure warning light
is on, visually check each tire to verify that no tire is flat. If one or more
tires are flat, repair as necessary. Check air pressure in the road tires. If
any tire is under-inflated, carefully drive the vehicle to the nearest
location where air can be added to the tires. Inflate all the tires to the
recommended inflation pressure.
