2021 FORD F-350 fuel

GENERAL INFORMATION
Use only approved wheel and tire sizes,
using other sizes could damage your
vehicle. If you change the diameter of the
tires from that fitted at the factory, the
speedometer may not display the correct
speed. If you intend to change the size of
the wheels from that fitted by the
manufacturer, you can check the suitability
with an authorized dealer.
Additional information related to the
functionality and maintenance of your tires
can be found later in this chapter. See Tire
Care (page 404).
You can find the recommended tire
inflation pressures can on the Tire Label,
which is on the B-pillar or the edge of the
driver door. You can also find this
information 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 seating position.
We strongly recommend maintaining these
tire pressures at all times. Failure to follow
the tire pressure recommendations can
cause uneven treadwear patterns, reduced
fuel economy, and adversely affect the
way your vehicle handles.
Note: 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.
Note: Check your tire pressures at least
once per month.
If your vehicle has a spare tire, set the
pressure to the highest value given for your
vehicle and tire size combination. Notice to utility vehicle and truck
owners WARNING:
Utility vehicles have a
significantly higher rollover rate than
other types of vehicles. WARNING:
Vehicles with a higher
center of gravity (utility and four-wheel
drive vehicles) handle differently than
vehicles with a lower center of gravity
(passenger cars). Avoid sharp turns,
excessive speed and abrupt steering in
these vehicles. Failure to drive cautiously
increases the risk of losing control of your
vehicle, vehicle rollover, personal injury
and death. WARNING:
In a rollover crash, an
unbelted person is significantly more
likely to die than a person wearing a
seatbelt. WARNING:
Do not become
overconfident in the ability of four-wheel
drive vehicles. Although a four-wheel
drive vehicle may accelerate better than
a two-wheel drive vehicle in low traction
situations, it won't stop any faster than
two-wheel drive vehicles. Always drive
at a safe speed.
Utility vehicles and trucks handle
differently than passenger cars in the
various driving conditions that are
encountered on streets, highways and
off-road. Utility vehicles and trucks are not
designed for cornering at speeds as high
as passenger cars any more than low-slung
sports cars are designed to perform
satisfactorily under off-road conditions.

Replacing a Tire That is
Greenhouse Gas Certified
The tires installed on this vehicle
at the factory as original
equipment are certified for
Greenhouse Gas and Fuel
Efficiency regulations.
Replacement tires must be of
equal or lower rolling resistance
level (TRRL or Crr). Consult with
your tire supplier(s) for
appropriate replacement tires.
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
’s 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 wheel and
replace it with your spare tire and
wheel. 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.

Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 202008, Third-Printing- Wheels and Tires

non-recommended tires and wheels can
cause steering, suspension, axle, transfer
case or power transfer unit failure.
Follow the Ford recommended tire
inflation pressure found on the Safety
Compliance Certification Label (on the
door hinge pillar, door latch post or the
door edge that meets the door latch
post, next to the driver seat), or Tire
Label 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.
WARNING: Do not use snow chains
on snow-free roads.
Note: Do not use snow chains on vehicles
with LT275/65R20 or LT 285/75R18 sized
tires.
The tires on your vehicle have all-weather
treads to provide traction in rain and snow.
However, in some climates, you may need
to use snow tires and cables. If you need
to use cables, we recommend that you use
steel wheels of the same size and
specification, as cables may chip
aluminum wheels.
Note: The suspension insulation and
bumpers will help prevent vehicle damage.
Do not remove these components from your
vehicle when using snow tires and chains.
Follow these guidelines when using snow
tires and chains:
• If possible, avoid fully loading your
vehicle.
• Use only SAE Class S chains.
• Install chains securely, verifying that
the chains do not touch any wiring,
brake lines or fuel lines.
• Only install snow chains on the rear
axle. •
For Dual Rear Wheel (DRW) vehicles,
only install snow chains on the outer
wheel of each pair.
• Drive cautiously. If you hear the chains
rub or bang against your vehicle, stop
and retighten the chains. If this does
not work, remove the chains to prevent
damage to your vehicle.
• Remove the tire chains when you no
longer need them. Do not use tire
chains on dry roads.
If you have any questions regarding snow
chains or cables, please contact your
authorized dealer.
TIRE PRESSURE MONITORING
SYSTEM
Vehicle Tire Pressure Monitoring
System WARNING:
The tire pressure
monitoring system is not a substitute for
manually checking tire pressures. You
should periodically check tire pressures
using a pressure gauge. Failure to
correctly maintain tire pressures could
increase the risk of tire failure, loss of
control, vehicle rollover and personal
injury. Check each tire, including the
spare, if provided, monthly when
cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer on the vehicle placard or tire
inflation pressure label. If your vehicle has
tires of a different size than the size
indicated on the vehicle placard or tire
inflation pressure label, you should
determine the proper tire inflation pressure
for those tires.

As an added safety feature, your vehicle
has been equipped with a Tire Pressure
Monitoring System (TPMS) that
illuminates a low tire pressure telltale
when one or more of your tires is
significantly under-inflated. Accordingly,
when the low tire pressure telltale
illuminates, you should stop and check
your tires as soon as possible, and inflate
them to the proper pressure. Driving on a
significantly under-inflated tire causes the
tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency
and tire tread life, and may affect the
vehicle
’s handling and stopping ability.
Please note that the TPMS is not a
substitute for proper tire maintenance, and
it is the driver's responsibility to maintain
correct tire pressure, even if under-inflation
has not reached the level to trigger
illumination of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped with
a TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is
combined with the low tire pressure
telltale. When the system detects a
malfunction, the telltale flashes for
approximately one minute and then
remains continuously illuminated. This
sequence continues upon subsequent
vehicle start-ups as long as the
malfunction exists.
When the malfunction indicator is
illuminated, the system may not be able
to detect or signal low tire pressure as
intended. TPMS malfunctions may occur
for a variety of reasons, including the
installation of replacement or alternate
tires or wheels on the vehicle that prevent
the TPMS from functioning properly. Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and wheels
allow the TPMS to continue to function
properly.
This device complies with Part 15 of the
FCC Rules and with Industry Canada
license-exempt RSS standard(s).
Operation is subject to the following two
conditions:
•
This device may not cause harmful
interference.
• This device must accept any
interference received, including
interference that may cause undesired
operation.
Note: Changes or modifications not
expressively approved by the party
responsible for compliance could void the
user's authority to operate the equipment.
The term "IC" before the radio certification
number only signifies that Industry Canada
technical specifications were met.
