TIRE CARE
Important Information for
235/40R18 Low-Profile Tires
and Wheels
If your vehicle is equipped with
235/40R18 tires, they are
low-profile tires. These tires and
wheels are designed to give your
vehicle a sport appearance. With
low-profile tires, you may notice
an increase in road noise and
faster tire wear, depending on
road conditions and driving styles.
Due to their design, low-profile
tires and wheels are more prone
to road damage from potholes,
rough or unpaved roads, car wash
rails and curb contact than
standard tires and wheels.
Note:
Your vehicle ’s warranty does
not cover these types of damage.
Tires should always be kept at the
correct inflation pressures and
extra caution should be taken when
operating on rough roads to avoid
impacts that could cause wheel
and tire damage. 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 ©)(2).

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

J.
Tire Ply Composition and
Material Used: Indicates the
number of plies or the number of
layers of rubber-coated fabric in
the tire tread and sidewall. Tire
manufacturers also must indicate
the ply materials in the tire and the
sidewall, which include steel,
nylon, polyester, and others.
K. Maximum Load: Indicates the
maximum load in kilograms and
pounds that can be carried by the
tire. Refer to 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
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 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.

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.

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 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! 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.
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 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 or 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.
253
Focus (CDH) Canada/United States of America, HM5J 19A321 AA enUSA, Edition date: 201608, First Printing Wheels and Tires

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 (7 kPa) 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 mile
[1.6 kilometers], 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. 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, refer to 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, refer to 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.

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
(such as load, speed, inflation
pressure, etc.) the tires experience
throughout their lives.
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 United States 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 United States 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.
WARNINGS
Only use replacement tires
and wheels that are the same
size, load index, speed rating and
type (such as P-metric versus
LT-metric or all-season versus
all-terrain) as those originally
provided by Ford. The
recommended tire and wheel size
256
Focus (CDH) Canada/United States of America, HM5J 19A321 AA enUSA, Edition date: 201608, First Printing Wheels and Tires

WARNINGS
may be found on either 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 the Tire Label which
is located on the B-Pillar or edge
of the driver ’s door. If this
information is not found on these
labels, then you should contact
your authorized dealer as soon as
possible. Use of any tire or wheel
not recommended by Ford can
affect the safety and performance
of your vehicle, which could result
in an increased risk of loss of
vehicle control, vehicle rollover,
personal injury and death.
Additionally the use of
non-recommended tires and
wheels could cause steering,
suspension, axle, transfer case or
power transfer unit failure. If you
have questions regarding tire
replacement, contact your
authorized dealer as soon as
possible. 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. WARNINGS
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.
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.
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.
