2002 FORD F150 tires

Never drive with chains on the front tires of 4WD vehicles without also
putting them on the rear tires. This could cause the rear to slide and
swing around during braking.
Tires, Replacement Requirements
4WD vehicles are equipped with tires designed to provide for safe ride
and handling capability.
Do not use a size and type of tire and wheel other than that originally
provided by Ford because it can affect the safety and performance of
your vehicle, which could lead to loss of vehicle control or roll over and
serious injury. Make sure all tires and wheels on the vehicle are of the
same size, type, tread design, brand and load-carrying capacity. If you
have questions regarding tire replacement, see an authorized Ford or
Lincoln/Mercury dealer.
If you nevertheless decide to equip your 4WD for off-road use with tires
larger than what Ford recommends, you should not use these tires for
highway driving.
If you use any tire/wheel combination not recommended by Ford, it may
adversely affect vehicle handling and could cause steering, suspension,
axle or transfer case failure.
Do not useºaftermarket lift kitsº or other suspension modifications,
whether or not they are used with larger tires and wheels.
These ªaftermarket lift kitsº could adversely affect the vehicle's handling
characteristics, which could lead to loss of vehicle control or roll over
and serious injury.
Tires can be damaged during off-road use. For your safety, tires that are
damaged should not be used for highway driving because they are more
likely to blow out or fail.
You should carefully observe the recommended tire inflation pressure
found on the safety compliance certification label attached to the left
front door lock facing or door latch post pillar. Failure to follow tire
pressure recommendations can adversely affect the way your vehicle
handles. Do not exceed the Ford recommended pressure even if it is less
than the maximum pressure allowed for the tire.

Each 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. Check tire pressure with a
tire gauge every few weeks
(including spare). Safe operation
requires tires that are neither
underinflated nor overloaded.
Periodically inspect the tire treads and remove stones, nails, glass or
other objects that may be wedged in the tread grooves. Check for holes
or cuts that may permit air leakage from the tire and make necessary
repairs.
Inspect the tire side walls for cuts, bruises and other damage. If internal
damage to the tire is suspected, have the tire demounted and inspected
in case it needs to be repaired or replaced.
Maintenance and Modifications
The suspension and steering systems on your vehicle have been designed
and tested to provide both reasonably safe, predictable performance
whether loaded or empty and durable load carrying capability. For this
reason, Ford strongly recommends that you do not make modifications
such as adding or removing parts (such as lift kits or stabilizer bars) or
by using replacement parts not equivalent to the original factory
equipment.
Any modifications to a vehicle that raise the center of gravity can make
it more likely the vehicle will roll over as a result of a loss of control.
Ford recommends that caution be used with any vehicle equipped with a
high load or device (such as ladder racks or pickup box cover).
Failure to maintain your vehicle properly may void the warranty, increase
your repair cost, reduce vehicle performance and operational capabilities
and adversely affect driver and passenger safety. Frequent inspection of
vehicle chassis components is recommended if the vehicle is subjected to
heavy off-road usage.

²Maximum Trailer Weight Rating:Maximum weight of a trailer the
vehicle is permitted to tow. The maximum trailer weight rating is
determined by subtracting the vehicle curb weight for each
engine/transmission combination, any required option weight for trailer
towing and the weight of the driver from the GCWR for the towing
vehicle.
²Maximum Trailer Weight:Maximum weight of a trailer the loaded
vehicle (including occupants and cargo) is permitted to tow. It is
determined by subtracting the weight of the loaded trailer towing
vehicle from the GCWR for the towing vehicle.
²Trailer Weight Range:Specified weight range that the trailer must
fall within that ranges from zero to the maximum trailer weight rating.
Remember to figure in the tongue load of your loaded trailer when
figuring the total weight.
Do not exceed the GVWR or the GAWR specified on the
certification label.
Do not use replacement tires with lower load carrying capacities than the
originals because they may lower the vehicle's GVWR and GAWR
limitations. Replacement tires with a higher limit than the originals do
not increase the GVWR and GAWR limitations.
The Safety Certification Label, found on the driver's door pillar, lists
several important vehicle weight rating limitations. Before adding any
additional equipment, refer to these limitations. If you are adding weight
to the front of your vehicle, (potentially including weight added to the
cab), the weight added should not exceed the front axle reserve capacity
(FARC). Additional frontal weight may be added to the front axle reserve
capacity provided you limit your payload in other ways (i.e. restrict the
number of occupants or amount of cargo carried).
Always ensure that the weight of occupants, cargo and equipment being
carried is within the weight limitations that have been established for
your vehicle including both gross vehicle weight and front and rear gross
axle weight rating limits. Under no circumstance should these limitations
be exceeded.
Exceeding any vehicle weight rating limitation could result in
serious damage to the vehicle and/or personal injury.

Special loading instructions for owners of pickup trucks and
utility-type vehicles
For important information regarding safe operation of this type
of vehicle, see thePreparing to drive your vehiclesection in
this chapter.
Loaded vehicles, with a higher center of gravity, may handle
differently than unloaded vehicles. Extra precautions, such as
slower speeds and increased stopping distance, should be taken when
driving a heavily loaded vehicle.
Your vehicle has the capability to haul more cargo and people than most
passenger cars. Depending upon the type and placement of the load,
hauling cargo and people may raise the center of gravity of the vehicle.
Calculating the load your vehicle can carry/tow
1.
Use the appropriate maximum gross combined weight rating (GCWR)
chart to find the maximum GCWR for your type engine and rear axle ratio.
2. Weigh your vehicle as you customarily operate the vehicle without
cargo. To obtain correct weights, try taking your vehicle to a shipping
company or an inspection station for trucks.
3. Subtract your loaded vehicle weight from the maximum GCWR on the
following charts. This is the maximum trailer weight your vehicle can tow
and must fall below the maximum shown under maximum trailer weight
on the chart.
TRAILER TOWING
Your vehicle may tow a class I, II or III trailer provided the maximum
trailer weight is less than or equal to the maximum trailer weight listed
for your engine and rear axle ratio on the following charts.
Your vehicle's load capacity is designated by weight, not by volume, so
you cannot necessarily use all available space when loading a vehicle.
Towing a trailer places an additional load on your vehicle's engine,
transmission, axle, brakes, tires and suspension. Inspect these
components carefully periodically during, and after any towing operation.
Exceeding the maximum GCWR could result in extensive damage
to your vehicle and personal injury.

RECREATIONAL TOWING (ALL WHEELS ON THE GROUND)
An example of recreational towing would be towing your vehicle behind a
motorhome. Follow these guidelines if you have the need for recreational
towing your vehicle with all four wheels on the ground. These guidelines are
designed to ensure that your transmission is not damaged.
2WD vehicles (with automatic transmissions)
²Place the transmission in N (Neutral)
²Maximum speed is 56 km (35 mph)
²Maximum distance is 80 km (50 miles)
If a distance of 80 km (50 miles) or a speed of 56 km (35 mph) must be
exceeded, the drive shaft will have to be removed before the vehicle is towed.
Ford recommends the driveshaft be removed/installed only by a qualified
technician. See your local dealer for driveshaft removal/installation.
Improper removal/installation of the driveshaft can cause
transmission fluid loss, damage to the driveshaft and internal
transmission components.
4WD vehicles electronic shift transfer case (with automatic
transmissions)
4x4 vehicles with electronic shift on the fly cannot be towed with any
wheels on the ground.
SNOWPLOWING
Ford recommends the following specifications for low speed, personal
use snow removal:
²
F-150 4x4 (except F-150 Supercrew, ªLightningº and ªHarley-Davidsonº)
²5.4L engine
²Heavy duty service package
²Super engine cooling
²Heavy duty front suspension package
²Automatic transmission with auxiliary automatic transmission fluid
cooling
²All-terrain tires
²Limited slip and optional axle ratio.
Do not install a snowplow and plow with your vehicle until it has been
driven at least 800 km (500 miles).
Driving
206

Engine temperature while plowing
When driving with a plow, your
engine may run at a higher
temperature than normal because
the attached snowplow blade will
restrict airflow to the radiator.
If you are driving more than 24 km (15 miles) at temperatures above
freezing, angle the plow blade either full left or full right to provide
maximum airflow to the radiator.
If you are driving less than 24 km (15 miles) at speeds up to 64 km/h
(40 mph) in cold weather, you will not need to worry about blade
position to provide maximum airflow.
Transmission operation while plowing
²Shift transfer case to 4L (4WD Low) when plowing in small areas at
speeds below 8 km/h (5 mph).
²Shift transfer case to 4H (4WD High) when plowing larger areas or
light snow at higher speeds. Do not exceed 24 km/h (15 mph).
²Do not shift the transmission from a forward gear to R (Reverse) until
the engine is at idle and the wheels are stopped.
²If the vehicle is stuck, shift the transmission in a steady motion
between forward and reverse gears. Do not rock the vehicle for more
than a few minutes. The transmission and tires may be damaged or
the engine can overheat.
Do not rock the vehicle if the engine is not at operating
temperature. Do not rock the vehicle for more than a few
minutes. The transmission and tires may be damaged or the
engine may overheat.
Do not spin the wheels at over 35 mph (55 km/h). The tires may
fail and injure a passenger or bystander.

CHANGING THE TIRES
If you get a flat tire while driving, do not apply the brake heavily.
Instead, gradually decrease your speed. Hold the steering wheel firmly
and slowly move to a safe place on the side of the road.
Spare tire information
Your vehicle is equipped with a spare tire that may be used as a spare or
a regular tire. The spare tire wheel may not match the road wheel, and is
not equipped with wheel trim. The wheel trim from the wheel/tire may
be used on the spare if the wheels match.
If your vehicle is equipped with 4WD, a spare tire of a different
size than the road tires should not be used. Such a tire could
result in damage to driveline components and make the vehicle
difficult to control.
Roadside Emergencies
220

²Using the air conditioner or defroster may reduce fuel economy.
²You may want to turn off the speed control in hilly terrain if
unnecessary shifting between third and fourth gear occurs.
Unnecessary shifting of this type could result in reduced fuel
economy.
²Warming up a vehicle on cold mornings is not required and may
reduce fuel economy.
²Resting your foot on the brake pedal while driving may reduce fuel
economy.
²Combine errands and minimize stop-and-go driving.
Maintenance
²Keep tires properly inflated and use only recommended size.
²Operating a vehicle with the wheels out of alignment will reduce fuel
economy.
²Use recommended engine oil. Refer toLubricant specificationsin
this chapter.
²Perform all regularly scheduled maintenance items. Follow the
recommended maintenance schedule and owner maintenance checks
found in your vehicle scheduled maintenance guide.
Conditions
²Heavily loading a vehicle or towing a trailer may reduce fuel economy
at any speed.
²Carrying unnecessary weight may reduce fuel economy (approximately
0.4 km/L [1 mpg] is lost for every 180 kg [400 lb] of weight carried).
²Adding certain accessories to your vehicle (for example bug
deflectors, rollbars/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
²To maximize the fuel economy, drive with the tonneau cover installed
(if equipped).
²Using fuel blended with alcohol may lower fuel economy.
²Fuel economy may decrease with lower temperatures during the first
12±16 km (8±10 miles) of driving.
²Driving on flat terrain offers improved fuel economy as compared to
driving on hilly terrain.
