Ford Motor Company recommends separate
functioning brake systems for trailers
weighing more than 1,500 lb (680 kg) when
loaded.
TOWING A TRAILER LIMITATIONS
The vehicle's load capacity designation
is by weight, not by volume, so you
cannot necessarily use all available
space when loading a vehicle or trailer.
Note: Your vehicle could have reduced
performance when operating at high
altitudes and when heavily loaded or
towing a trailer. When driving at
elevation, to match driving performance
as perceived at sea level, reduce gross
vehicle weight and gross combination
weight by 2% per
1,000 ft (300 m)
elevation. LOADING YOUR TRAILER
To help minimize how trailer movement
affects your vehicle when driving:
•
Load the heaviest items closest to
the trailer floor.
• Load the heaviest items centered
between the left and right side trailer
tires.
• Load the heaviest items above the
trailer axles or just slightly forward
toward the trailer tongue. Do not
allow the final trailer tongue weight
to go above or below 10-15% of the
loaded trailer weight. The trailer
tongue weight should never exceed
10% of the maximum towing capacity.
• Select a ball mount with the correct
rise or drop. When both the loaded
vehicle and trailer are connected, the
trailer frame should be level, or
slightly angled down toward your
vehicle, when viewed from the side. TRAILER TOWING HINTS
Towing a trailer places an extra load on your
vehicle's engine, transmission, axle, brakes,
tires and suspension. Periodically inspect
these components during and after any
towing operation.
When driving with a trailer or payload, a slight
takeoff vibration or shudder may be present
due to the increased payload weight.
Your vehicle may have a temporary or
conventional spare tire. A temporary spare
tire is different in diameter or width,
tread-type, 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.
When towing a trailer:
•
Obey country specific regulations for
towing a trailer.
• Do not drive faster than
70 mph
(113 km/h) during the first 500 mi
(800 km).
• Do not make full-throttle starts.

LOCATING 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.
See Locating the Safety Compliance
Certification Labels (page 290).
DEPARTMENT OF
TRANSPORTATION UNIFORM TIRE
QUALITY GRADES 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.
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 (c)(2).
U.S. Department of Transportation Tire
quality grades: The U.S. Department of
Transportation requires us to give you
the following information about tire
grades exactly as the government has
written it. 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 1½ 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.
363
2021 Nautilus (CD9) Canada/United States of America, enUSA, Edition date: 202011, First-Printing Wheel and Tire InformationE142542

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 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

C.
65: Indicates the aspect ratio which
gives the tire's ratio of height to width.
D.

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

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

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.

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

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.
