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
81–186 mph (130–299 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.

K. Maximum Load: Indicates the
maximum load in kilograms and pounds
that can be carried by the tire. See 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), for the correct
tire pressure for your vehicle.
L.
Treadwear, Traction and
Temperature Grades: •
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 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 generation of heat and its ability
to dissipate heat when tested under
controlled conditions on a specified
indoor laboratory test wheel. M.
Maximum Inflation Pressure:
Indicates the tire manufacturers'
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 Tires

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.
Inflating Your Tires
Safe operation of your vehicle requires
that your tires are properly inflated.
Remember that a tire can lose up to half
of its air pressure without appearing flat.
Every day before you drive, check your
tires. If one looks lower than the others,
use a tire gauge to check pressure of all
tires and adjust if required.
At least once a month and before long
trips, inspect each tire and check the tire
pressure with a tire gauge (including
spare, if equipped). Inflate all tires to the
inflation pressure recommended by Ford
Motor Company. You are strongly urged to buy a reliable
tire pressure gauge, as automatic
service station gauges may be
inaccurate. Ford recommends the use
of a digital or dial-type tire pressure
gauge rather than a stick-type tire
pressure gauge.
Use the recommended cold inflation
pressure for optimum tire performance
and wear. Under-inflation or
over-inflation may cause uneven
treadwear patterns
WARNING: Under-inflation is the
most common cause of tire failures
and may result in severe tire cracking,
tread separation or blowout, with
unexpected loss of vehicle control and
increased risk of injury. Under-inflation
increases sidewall flexing and rolling
resistance, resulting in heat buildup
342
MKZ (CC9) Canada/United States of America, enUSA, Edition date: 201905, Second-Printing Wheels and Tires

and internal damage to the tire. It also
may result in unnecessary tire stress,
irregular wear, loss of vehicle control
and accidents. A tire can lose up to
half of its air pressure and not appear
to be flat!
Always inflate your tires to the Ford
recommended inflation pressure even
if it is less than the maximum inflation
pressure information found on the tire.
The Ford recommended tire inflation
pressure is 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. Failure to follow the tire
pressure recommendations can cause
uneven treadwear patterns and
adversely affect the way your vehicle
handles Maximum Inflation Pressure is the tire
manufacturer's maximum permissible
pressure and the pressure at which the
maximum load can be carried by the tire.
This pressure is normally higher than the
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 Safety Compliance Certification
Label or Tire Label.
When weather temperature changes
occur, tire inflation pressures also
change. A 10°F (6°C) temperature drop
can cause a corresponding drop of 1 psi
(0.07 bar)
in inflation pressure. Check
your tire pressures frequently and adjust
them to the proper pressure which can
be found on the Safety Compliance
Certification Label or Tire Label. To check the pressure in your tire(s):
1. Make sure the tires are cool,
meaning they are not hot from
driving even a mile.
Note: If you are checking tire pressure
when the tire is hot, (for example driven
more than
1.0 mi (1.6 km), never bleed
or reduce air pressure. The tires are hot
from driving and it is normal for
pressures to increase above
recommended cold pressures. A hot tire
at or below recommended cold inflation
pressure could be significantly
under-inflated.
Note: If you have to drive a distance to
get air for your tire(s), check and record
the tire pressure first and add the
appropriate air pressure when you get
to the pump. It is normal for tires to heat
up and the air pressure inside to go up
as you drive.
2. Remove the cap from the valve on
one tire, then firmly press the tire
gauge onto the valve and measure
the pressure.
343
MKZ (CC9) Canada/United States of America, enUSA, Edition date: 201905, Second-Printing Wheels and Tires

3. Add enough air to reach the
recommended air pressure.
Note: If you overfill the tire, release air
by pressing on the metal stem in the
center of the valve. Then recheck the
pressure with your tire gauge.
4. Replace the valve cap.
5. Repeat this procedure for each tire,
including the spare.
Note: Some spare tires operate at a
higher inflation pressure than the other
tires. For T type mini-spare tires, see the
Dissimilar spare wheel and tire
assembly information for a description.
Store and maintain at 60 psi (4.15 bar).
For full-size and dissimilar spare tires,
see the Dissimilar spare wheel and tire
assembly information for a description.
Store and maintain at the higher of the
front and rear inflation pressure as
shown on the Tire Label. 6.
Visually inspect the tires to make
sure there are no nails or other
objects embedded that could poke
a hole in the tire and cause an air
leak.
7. Check the sidewalls to make sure there are no gouges, cuts or bulges.
Inspecting Your Tires and Wheel Valve
Stems
Periodically inspect the tire treads for
uneven or excessive wear and remove
objects such as stones, nails or glass
that may be wedged in the tread
grooves. Check the tire and valve stems
for holes, cracks, or cuts that may permit
air leakage and repair or replace the tire
and replace the valve stem. Inspect the
tire sidewalls for cracking, cuts, bruises
and other signs of damage or excessive
wear. If internal damage to the tire is
suspected, have the tire demounted and
inspected in case it needs to be repaired
or replaced. For your safety, tires that
are damaged or show signs of excessive
wear should not be used because they
are more likely to blow out or fail. Improper or inadequate vehicle
maintenance can cause tires to wear
abnormally. Inspect all your tires,
including the spare, frequently, and
replace them if one or more of the
following conditions exist:
Tire Wear
344
MKZ (CC9) Canada/United States of America, enUSA, Edition date: 201905, Second-Printing Wheels and TiresE142546

When the tread is worn down to 0.08 in
(2 mm), tires must be replaced to help
prevent your vehicle from skidding and
hydroplaning. Built-in treadwear
indicators, or wear bars, which look like
narrow strips of smooth rubber across
the tread will appear on the tire when
the tread is worn down to
0.08 in
(2 mm).
When the tire tread wears down to the
same height as these wear bars, the tire
is worn out and must be replaced.
Damage
Periodically inspect the tire treads and
sidewalls for damage (such as bulges in
the tread or sidewalls, cracks in the
tread groove and separation in the tread
or sidewall). If damage is observed or
suspected have the tire inspected by a
tire professional. Tires can be damaged
during off-road use, so inspection after
off-road use is also recommended. Age WARNING:
Tires degrade over
time depending on many factors such
as weather, storage conditions, and
conditions of use (load, speed, inflation
pressure) the tires experience
throughout their lives. WARNING:
In general, tires
should be replaced after six years
regardless of tread wear. However,
heat caused by hot climates or
frequent high loading conditions can
accelerate the aging process and may
require tires to be replaced more
frequently.
You should replace your spare tire
when you replace the road tires or
after six years due to aging even if it
has not been used. U.S. DOT Tire Identification Number
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.
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.

Tire Replacement Requirements
Your vehicle is equipped with tires
designed to provide a safe ride and
handling capability.
WARNING: Replace the wheels
and tires with the exact original brand,
size and construction that came
originally on your vehicle. Use of any
other wheel or tire combinations, even
with identical size ratings, may result
in insufficient running clearances, tire
rubbing and eventual puncture. Failure
to follow tire replacement
recommendations can lead to tire
failure, loss of vehicle control, serious
injury or death. WARNING: To reduce the risk of
serious injury, when mounting
replacement tires and wheels, you
should not exceed the maximum
pressure indicated on the sidewall of
the tire to set the beads without
additional precautions listed below. If
the beads do not seat at the maximum
pressure indicated, re-lubricate and
try again. WARNING:
When inflating the
tire for mounting pressures up to
20 psi (1.38 bar)
greater than the
maximum pressure on the tire sidewall,
the following precautions must be
taken to protect the person mounting
the tire:
1. Make sure that you have the correct
tire and wheel size.
2. Lubricate the tire bead and wheel
bead seat area again. 3. Stand at a minimum of
12 ft (3.66 m)
away from the wheel and tire
assembly.
4. Use both eye and ear protection. WARNING:
For a mounting
pressure more than 20 psi (1.38 bar)
greater than the maximum pressure,
a Ford dealer or other tire service
professional should do the mounting. WARNING:
Always inflate steel
carcass tires with a remote air fill with
the person inflating standing at a
minimum of
12 ft (3.66 m) away from
the wheel and tire assembly.
Important:
Remember to replace the
wheel valve stems when the road tires
are replaced on your vehicle
It is recommended that the two front
tires or two rear tires generally be
replaced as a pair.
346
MKZ (CC9) Canada/United States of America, enUSA, Edition date: 201905, Second-Printing Wheels and Tires

The tire pressure sensors mounted in
the wheels (originally installed on your
vehicle) are not designed to be used in
aftermarket wheels.
The use of wheels or tires not
recommended by Ford Motor Company
may affect the operation of your tire
pressure monitoring system.
If the tire pressure monitoring system
indicator is flashing, your system is
malfunctioning. Your replacement tire
might be incompatible with your tire
pressure monitoring system, or some
component of the system may be
damaged.
Safety Practices
WARNING: If your vehicle is
stuck in snow, mud or sand, do not
rapidly spin the tires; spinning the tires
can tear the tire and cause an
explosion. A tire can explode in as little
as three to five seconds. WARNING:
Do not spin the
wheels at over 34 mph (55 km/h). The
tires may fail and injure a passenger
or bystander.
Driving habits have a great deal to do
with your tire mileage and safety.
• Observe posted speed limits
• Avoid fast starts, stops and turns
• Avoid potholes and objects on the
road
• Do not run over curbs or hit the tire
against a curb when parking
Highway Hazards
No matter how carefully you drive there
is always the possibility that you may
eventually have a flat tire on the
highway. Drive slowly to the closest safe
area out of traffic. This may further
damage the flat tire, but your safety is
more important. If you feel a sudden vibration or ride
disturbance while driving, or you suspect
your tire or vehicle has been damaged,
immediately reduce your speed. Drive
with caution until you can safely pull off
the road. Stop and inspect the tires for
damage. If a tire is under-inflated or
damaged, deflate it, remove the wheel
and replace it with your spare tire and
wheel (if provided). If you cannot detect
a cause, have the vehicle towed to the
nearest repair facility or tire dealer to
have the vehicle inspected.
Tire and Wheel Alignment
A bad jolt from hitting a curb or pothole
can cause the front end of your vehicle
to become misaligned or cause damage
to your tires. If your vehicle seems to
pull to one side when you’re driving, the
wheels may be out of alignment. Have
an authorized dealer check the wheel
alignment periodically.
347
MKZ (CC9) Canada/United States of America, enUSA, Edition date: 201905, Second-Printing Wheels and Tires

Wheel misalignment in the front or the
rear can cause uneven and rapid
treadwear of your tires and should be
corrected by an authorized dealer.
Front-wheel drive vehicles and those
with an independent rear suspension (if
equipped) may require alignment of all
four wheels.
The tires should also be balanced
periodically. An unbalanced tire and
wheel assembly may result in irregular
tire wear.
Tire Rotation
Note:
If your tires show uneven wear
ask an authorized dealer to check for
and correct any wheel misalignment,
tire imbalance or mechanical problem
involved before tire rotation. Note:
Your vehicle may be equipped
with a dissimilar spare wheel and tire
assembly. A dissimilar spare wheel and
tire assembly is defined as a spare
wheel and tire assembly that is different
in brand, size or appearance from the
road tires and wheels. If you have a
dissimilar spare wheel and tire assembly
it is intended for temporary use only and
should not be used in a tire rotation.
Note: After having your tires rotated,
inflation pressure must be checked and
adjusted to the vehicle requirements.
Rotating your tires at the recommended
interval (as indicated in the Scheduled
Maintenance chapter) will help your tires
wear more evenly, providing better tire
performance and longer tire life.
Front-wheel drive and all-wheel drive
vehicles (front tires on the left side of
the diagram) All vehicles with directional tires (front
tires on the left of the diagram)
Sometimes irregular tire wear can be
corrected by rotating the tires.
