2013 FORD EXPLORER tire size

USING YOUR FOUR WHEEL DRIVE (4WD) SYSTEM
The intelligent 4WD system continuously monitors vehicle conditions and
automatically adjusts the power distribution between the front and rear
wheels. It combines transparent all-surface operation with highly capable
four-wheel drive.
The 4WD system is always active and requires no driver input. It is
capable of handling all road conditions, including street and highway
driving as well as off-road and winter driving. The driver can optimize
more 4WD control by moving the terrain management switch for the
correct terrain. See theTerrain Managementchapter for more
information.
Note:When an 4WD system fault is present, the warning Check 4WD
will display in the message center. The 4WD system is not functioning
correctly and will default to front-wheel drive. When this warning is
displayed, have your vehicle serviced at an authorized dealer.
Note:The 4WD Off message may also be displayed in the message
center if the 4WD system has overheated and defaulted to front-wheel
drive. This condition may occur if the vehicle was operated in extreme
conditions with excessive wheel slip, such as deep sand. To resume
normal 4WD function as soon as possible, stop the vehicle in a safe
location and stop the engine for at least 10 minutes. After the engine has
been restarted and the 4WD system has adequately cooled, the 4WD Off
message will turn off and normal 4WD function will return. The 4WD Off
message will turn off when the system cools and normal 4WD function
returns.
If your vehicle is equipped with 4WD, a spare tire of a different size
other than the tire provided should never be used. If the mini-spare tire
is installed, the 4WD system may disable automatically and enter
front-wheel drive only mode to protect driveline components. This
condition may be indicated by an 4WD Off message in the information
display. If there is an 4WD Off message in the message center from using
the spare tire, this indicator should turn off after reinstalling the repaired
or replaced normal road tire and cycling the ignition off and on. It is
recommended to reinstall the repaired or replaced road tire as soon as
possible. Major dissimilar tire sizes between the front and rear axles
could cause the 4WD system to stop functioning and default to
front-wheel drive or damage the 4WD system.

PRINCIPLES OF OPERATION
WARNING:Vehicle modifications involving braking system,
aftermarket roof racks, suspension, steering system, tire
construction and/or wheel/tire size may change the handling
characteristics of the vehicle and may adversely affect the performance
of the AdvanceTracsystem. In addition, installing any stereo
loudspeakers may interfere with and adversely affect the AdvanceTrac
system. Install any aftermarket stereo loudspeaker as far as possible
from the front center console, the tunnel, and the front seats in order
to minimize the risk of interfering with the AdvanceTracsensors.
Reducing the effectiveness of the AdvanceTracsystem could lead to
an increased risk of loss of vehicle control, vehicle rollover, personal
injury and death.
WARNING:Remember that even advanced technology cannot
defy the laws of physics. It’s always possible to lose control of a
vehicle due to inappropriate driver input for the conditions. Aggressive
driving on any road condition can cause you to lose control of your
vehicle increasing the risk of personal injury or property damage.
Activation of the AdvanceTracsystem is an indication that at least
some of the tires have exceeded their ability to grip the road; this could
reduce the operator’s ability to control the vehicle potentially resulting
in a loss of vehicle control, vehicle rollover, personal injury and death. If
your AdvanceTracsystem activates, SLOW DOWN.
The AdvanceTracwith Roll Stability Control™ (RSC) system helps you
keep control of your vehicle when on a slippery surface. The electronic
stability control (ESC) portion of the system helps avoid skids and lateral
slides, curve control assists in vehicle handling in following the road
during adverse maneuvering and roll stability control helps avoid a
vehicle rollover. The traction control system (TCS) helps avoid drive
wheel spin and loss of traction. (For details on TCS operation, see the
Traction Controlchapter.)

The system does not position the vehicle where I want in the
space
The vehicle is rolling in the opposite direction of the transmission (i.e.
rolling forward when R [Reverse] is selected)
The transmission is in R (Reverse); the vehicle must be moving forward
to detect a parking space
An irregular curb along the parking space prevents the system from
aligning the vehicle properly
Vehicles or objects bordering the space may not be positioned correctly
The vehicle was pulled too far past the parking space. The system
performs best when you drive the same distance past the parking space
The tires may not be installed or maintained correctly (i.e. not inflated
correctly, improper size, or of different sizes)
A repair or alteration has changed detection capabilities
A parked vehicle has a high attachment (i.e. salt sprayer, snowplow,
moving truck bed, etc.)
The parking space length or position of parked objects changed after
your vehicle passed
The temperature around your vehicle changes quickly (i.e. driving from
a heated garage into the cold, or after leaving a car wash)
REAR VIEW CAMERA SYSTEM (IF EQUIPPED)
WARNING:The rear view camera system is a reverse aid
supplement device that still requires the driver to use it in
conjunction with the interior and exterior mirrors for maximum
coverage.
WARNING:Objects that are close to either corner of the bumper
or under the bumper, might not be seen on the screen due to the
limited coverage of the camera system.
WARNING:Back up as slow as possible since higher speeds
might limit your reaction time to stop the vehicle.

Blocked Sensor
WARNING:Do not use ACC when towing a trailer with brake
controls. Aftermarket trailer brakes will not function properly
when ACC is activated because the brakes are electronically controlled.
Failing to do so may result in loss of vehicle control, which could result
in serious injury.
WARNING:Do not use tires sizes other than those
recommended because this can affect the normal operation of
ACC. Failing to do so may result in a loss of vehicle control, which
could result in serious injury.
A message regarding a blocked
sensor is displayed if the radar
signals from the sensor have been
obstructed. The sensor is located
behind a fascia cover near the driver
side of the lower grille. A vehicle
ahead cannot be detected and the
system will not function when the
radar signals are obstructed. The
following table lists possible causes
and actions for this message being
displayed.
Cause Action
The surface of the radar in the
grille is dirty or obstructed in
some wayClean the grille surface in front of
the radar or remove the object
causing the obstruction
The surface of the radar in the
grille is clean but the message
remains in the displayWait a short time. It may take
several minutes for the radar to
detect that it is no longer
obstructed
Heavy rain or snow is interfering
with the radar signalsDo not use ACC in these condition
because it may not detect, warn,
or respond to potential collisions.

BREAKING-IN
Your vehicle does not need an extensive break-in. Try not to drive
continuously at the same speed for the first 1,000 miles (1,600 km) of
new vehicle operation. Vary your speed frequently in order to give the
moving parts a chance to break in.
Drive your new vehicle at least 1,000 miles (1,600 km) before towing a
trailer.
Do not add friction modifier compounds or special break-in oils since
these additives may prevent piston ring seating.
ECONOMICAL DRIVING
Fuel economy is affected by several things such as how you drive, the
conditions you drive under and how you maintain your vehicle.
There are some things to keep in mind that may improve your fuel
economy:
•Accelerate and slow down in a smooth, moderate fashion.
•Drive at steady speeds without stopping.
•Anticipate stops; slowing down may eliminate the need to stop.
•Combine errands and minimize stop-and-go driving.
•Close the windows for high-speed driving.
•Drive at reasonable speeds (traveling at 55 mph [88 km/h] uses 15%
less fuel than traveling at 65 mph [105 km/h]).
•Keep the tires properly inflated and use only the recommended size.
•Use the recommended engine oil.
•Perform all regularly scheduled maintenance.
There are also some things you may not want to do because they may
reduce your fuel economy:
•Sudden or hard accelerations.
•Rev the engine before turning it off.
•Idle for periods longer than one minute.
•Warm up your vehicle on cold mornings.
•Use the air conditioner or front defroster.
•Use the speed control in hilly terrain.
•Rest your foot on the brake pedal while driving.

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 properly inflated and not overloaded. Excessive
speed, underinflation, 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 of the amount of air in a tire.

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
(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).
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.
E.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.
F.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 manual. 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.

G.H:Indicates the tire’s speed rating. The speed rating denotes the
speed at which a tire is designed to be driven for extended periods of
time under a standard condition of load and inflation pressure. The tires
on your vehicle may operate at different conditions for load and inflation
pressure. These speed ratings may need to be adjusted for the difference
in conditions. The ratings range from 81 mph (130 km/h) to 186 mph
(299 km/h). These ratings are listed in the following chart.
Note:You may not find this information on all tires because it is not
required by federal law.
Letter rating Speed rating - mph (km/h)
M 81 mph (130 km/h)
N 87 mph (140 km/h)
Q 99 mph (159 km/h)
R 106 mph (171 km/h)
S 112 mph (180 km/h)
T 118 mph (190 km/h)
U 124 mph (200 km/h)
H 130 mph (210 km/h)
V 149 mph (240 km/h)
W 168 mph (270 km/h)
Y 186 mph (299 km/h)
Note:For tires with a maximum speed capability over 149 mph
(240 km/h), tire manufacturers sometimes use the letters ZR. For those
with a maximum speed capability over 186 mph (299 km/h), tire
manufacturers always use the letters ZR.
H.U.S. DOT Tire Identification Number (TIN):This begins with the
letters “DOT” and indicates that the tire meets all federal standards. The
next two numbers or letters are the plant code designating where it was
manufactured, the next two are the tire size code and the last four
numbers represent the week and year the tire was built. For example,
the numbers 317 mean the 31st week of 1997. After 2000 the numbers
go to four digits. For example, 2501 means the 25th week of 2001. The
numbers in between are identification codes used for traceability. This
information is used to contact customers if a tire defect requires a recall.
I.M+S or M/S:Mud and Snow, or
AT:All Terrain, or
AS:All Season.
