2017 LINCOLN NAVIGATOR tire size

PRINCIPLE OF OPERATION
WARNINGS
Vehicle modifications involving braking
system, aftermarket roof racks,
suspension, steering system, tire
construction and wheel and tire size may
change the handling characteristics of your
vehicle and may adversely affect the
performance of the electronic stability control
system. In addition, installing any stereo
loudspeakers may interfere with and
adversely affect the electronic stability
control 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 electronic stability control
sensors. Reducing the effectiveness of the
electronic stability control system could lead
to an increased risk of loss of vehicle control,
vehicle rollover, personal injury and death. WARNINGS
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
electronic stability control system 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 electronic stability
control system activates, SLOW DOWN. The system automatically turns on each time
you switch the ignition on.
If a fault occurs in either the stability control
or the traction control system, you may
experience the following conditions:•
The stability and traction control light
illuminates steadily.
• The stability control and traction control
systems do not enhance your vehicle's
ability to maintain traction of the wheels.
If a driving condition activates either the
stability control or the traction control system
you may experience the following conditions:
• The stability and traction control light
flashes.
• Your vehicle slows down.
• Reduced engine power.
• A vibration in the brake pedal.
• The brake pedal is stiffer than usual.
• If the driving condition is severe and your
foot is not on the brake, the brake pedal
may move as the system applies higher
brake force.
The stability control system has several
features built into it to help you maintain
control of your vehicle:

Your vehicle may be equipped with a
temporary or conventional spare tire. A
“temporary” spare tire is different in size
(diameter or width), tread-type (All-Season
or All-Terrain) or is from a different
manufacturer than the road tires on your
vehicle. Consult information on the tire label
or Safety Compliance label for limitations
when using.
Launching or Retrieving a Boat or
Personal Watercraft (PWC)
Note:
Disconnect the wiring to the trailer
before backing the trailer into the water.
Note: Reconnect the wiring to the trailer
after
removing the trailer from the water.
When backing down a ramp during boat
launching or retrieval:
• Do not allow the static water level to rise
above the bottom edge of the rear
bumper.
• Do not allow waves to break higher than
6 inches (15 centimeters) above the
bottom edge of the rear bumper. Exceeding these limits may allow water to
enter vehicle components:
•
Causing internal damage to the
components.
• Affecting driveability, emissions, and
reliability.
Replace the rear axle lubricant anytime the
rear axle has been submerged in water.
Water may have contaminated the rear axle
lubricant, which is not normally checked or
changed unless a leak is suspected or other
axle repair is required.
TOWING POINTS WARNINGS
Using recovery hooks is dangerous
and should only be done by a person
familiar with proper vehicle recovery safety
practices. Improper use of recovery hooks
may cause hook failure or separation from
the vehicle and could result in serious injury
or death. WARNINGS
Always slowly remove the slack from
the recovery strap prior to pulling.
Failure to do so can introduce significantly
higher loads which can cause the recovery
hooks to break off, or the recovery strap to
fail which can cause serious injury or death. Never link two straps together with a
clevis pin. These heavy metal objects
could become projectiles if the strap breaks
and can cause serious injury or death. Your vehicle comes equipped with
frame-mounted front recovery hooks. These
hooks should never have a load applied to
them greater than the gross vehicle weight
rating of your vehicle.
Before using recovery hooks:
•
Make sure all attaching points are secure
and capable of withstanding the applied
load.
• Never use chains, cables or tow straps
with metal hook ends.

BREAKING-IN
You need to break in new tires for
approximately 300 miles (480 kilometers).
During this time, your vehicle may exhibit
some unusual driving characteristics.
Avoid driving too fast during the first 1000
miles (1600 kilometers). Vary your speed
frequently and change up through the gears
early. Do not labor the engine.
Do not tow during the first 1000 miles (1600
kilometers).
REDUCED ENGINE PERFORMANCE
WARNING
Continued operation will increase the
engine temperature and cause the
engine to shut down completely. If the engine coolant temperature gauge
needle moves to the upper limit position, the
engine is overheating. See Gauges (page
96). You must only drive your vehicle for a short
distance if the engine overheats. The
distance you can travel depends on ambient
temperature, vehicle load and terrain. The
engine will continue to operate with limited
power for a short time.
If the engine temperature continues to rise,
the fuel supply to the engine will reduce. The
air conditioning will switch off and the engine
cooling fan will operate continually.
1. Reduce your speed gradually and stop
your vehicle as soon as it is safe to do
so.
2. Switch the engine off immediately to prevent severe engine damage.
3. Wait for the engine to cool down.
4. Check the coolant level.
See Engine
Coolant Check (page 268).
5. Have your vehicle checked by an authorized dealer as soon as possible. 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.
• Anticipate stops; slowing down may
eliminate the need to stop.
• Combine errands and minimize
stop-and-go driving (When running
errands, go to the furthest destination
first and then work your way back home).
• Close the windows for high-speed
driving.
• Drive at reasonable speeds.
• Keep the tires properly inflated and use
only the recommended size.
• Use the recommended engine oil.
• Perform all regularly scheduled
maintenance.

GENERAL INFORMATION
Use only approved wheel and tire sizes,
using other sizes could damage your vehicle.
If you change the diameter of the tires from
that fitted at the factory, the speedometer
may not display the correct speed. Take your
vehicle to an authorized Ford dealer to have
the system reprogrammed. If you intend to
change the size of the wheels from that fitted
by the manufacturer, you can check the
suitability with an authorized dealer.
Additional information related to the
functionality and maintenance of your tires
can be found later in this chapter. See Tire
Care (page 298).
The Ford recommended tire inflation
pressures can be found on the Tire Label,
which is located on the B-pillar or the edge
of the driver's door. This information can also
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 last post; next to the
driver’ s seating position). Ford strongly recommends maintaining these
tire pressures at all times. Failure to follow
the tire pressure recommendations can
cause uneven treadwear patterns, reduced
fuel economy, and adversely affect the way
your vehicle handles.
Note:
Check and set the tire pressure at the
ambient temperature in which you are
intending to drive your vehicle and when the
tires are cold.
Note: Check your tire pressures at least once
per month.
Set the pressure for your spare tire to the
highest value given for your vehicle and tire
size combination (if equipped). Notice to utility vehicle and truck
owners WARNINGS
Utility vehicles have a significantly
higher rollover rate than other types of
vehicles. To reduce the risk of serious injury
or death from a rollover or other crash you
must avoid sharp turns and abrupt
maneuvers, drive at safe speeds for the
conditions, keep tires inflated to Ford
recommended pressures, never overload or
improperly load your vehicle, and make sure
every passenger is properly restrained. In a rollover crash, an unbelted person
is significantly more likely to die than
a person wearing a seat belt. All occupants
must wear seat belts and children/infants
must use appropriate restraints to minimize
the risk of injury or ejection. Do not become overconfident in the
ability of four-wheel drive vehicles.
Although a four-wheel drive vehicle may
accelerate better than a two-wheel drive
vehicle in low traction situations, it won't stop
any faster than two-wheel drive vehicles.
Always drive at a safe speed. 295
Navigator (TB5) Canada/United States of America, enUSA, First Printing Wheels and Tires

Utility vehicles and trucks handle differently
than passenger cars in the various driving
conditions that are encountered on streets,
highways and off-road. Utility vehicles and
trucks are not designed for cornering at
speeds as high as passenger cars any more
than low-slung sports cars are designed to
perform satisfactorily under off-road
conditions.
Study your owner's manual and any
supplements for specific information about
equipment features, instructions for safe
driving and additional precautions to reduce
the risk of an accident or serious injury. Four-wheel drive system (If Equipped) WARNING
Do not become overconfident in the
ability of four-wheel drive vehicles.
Although a four-wheel drive vehicle may
accelerate better than a two-wheel drive
vehicle in low traction situations, it won't stop
any faster than two-wheel drive vehicles.
Always drive at a safe speed. A vehicle equipped with four-wheel drive
(when selected) has the ability to use all four
wheels to power itself. This increases traction
which may enable you to safely drive over
terrain and road conditions that a
conventional two-wheel drive vehicle cannot.
Power is supplied to all four wheels through
a transfer case or power transfer unit.
Four-wheel drive vehicles allow you to select
different modes as necessary. For
information on transfer case operation and
shifting procedures, See Four-Wheel Drive
(page
174). For information on transfer case
maintenance, See Maintenance (page 262).
You should become thoroughly familiar with
this information before you operate your
vehicle.
On some four-wheel drive vehicles, the initial
shift from two-wheel to four-wheel drive
while the vehicle is moving can cause a
momentary clunk and ratcheting sound.
These sounds are normal and are not cause
for concern.
For four-wheel drive vehicles, a spare tire of
a different size other than the tire provided
should never be used. A dissimilar spare tire
size (other than the spare tire provided) or
major dissimilar tire sized between the front
and rear axles could cause the four-wheel
drive system to stop functioning and default
to front-wheel drive. See Using Four-Wheel
Drive
(page 174).

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 ½) 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
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.

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.
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
