LT type tires have some additional
information beyond those of P
type tires; these differences are
described below.

Note: Tire Quality Grades do not
apply to this type of tire.

A. LT: Indicates a tire, designated
by the Tire and Rim Association,
that is intended for service on light
trucks.

B. Load Range and Load
Inflation Limits: Indicates the
tire's load-carrying capabilities
and its inflation limits.

C. Maximum Load Dual lb (kg)
at psi (kPa) cold: Indicates the
maximum load and tire pressure
when the tire is used as a dual,
defined as four tires on the rear
axle (a total of six or more tires on
the vehicle).

D. Maximum Load Single lb
(kg) at psi (kPa) cold: Indicates
the maximum load and tire
pressure when the tire is used as
a single, defined as two tires
(total) on the rear axle.

Information on T Type Tires

T type tires have some additional
information beyond those of P
type tires; these differences are
described below:

T145/80D16 is an example of a
tire size.

Note: The temporary tire size for
your vehicle may be different from
this example. Tire Quality Grades
do not apply to this type of tire.

A. T: Indicates a type of tire,
designated by the Tire and Rim
Association, that is intended for
temporary service on cars,
sport-utility vehicles, minivans and
light trucks.

B. 145: 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. 80: Indicates the aspect ratio
which gives the tire's ratio of
height to width. Numbers of 70 or
lower indicate a short sidewall.

D. D: Indicates a diagonal type tire.

R: Indicates a radial type tire.
E. 16: 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.

Location of the Tire Label

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 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.

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.

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.
