High cross winds are present.
There is a large road crown.
Rough roads, grooves or shoulder drop-offs.

GENERAL INFORMATION
The recommended tire inflation pressures
are on the tire information label on the driver
side B-pillar.
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. See Technical Specifications
(page 379).
Note: Check your tire pressures regularly to
optimize fuel economy.
Only use approved wheel and tire sizes.
Using other sizes could damage your vehicle
and could make the National Type Approval
invalid.
Installation of any tires that are not the
original equipment tire size can cause the
speedometer to display incorrect vehicle
speed. TIRE CARE
Important Information About Low-
Profile Tires
If your vehicle is equipped with
245/40R20 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 damages. 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
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.

Information Contained on the Tire
Sidewall
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 U.S. DOT Tire Identification
Number for safety standard certification
and in case of a recall.
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.

T type tires have some additional
information beyond those of P type tires;
these differences are described below: 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’
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.
