1999 FORD F150 tires

Changing the wiper blades
To replace the wiper blades:
1. Pull the wiper arm away from the
windshield and lock into the service
position.
2. Turn the blade at an angle from
the wiper arm. Push the lock pin
manually to release the blade and
pull the wiper blade down toward
the windshield to remove it from the
arm.
3. Attach the new wiper to the
wiper arm and press it into place
until a click is heard.
INFORMATION ABOUT TIRE QUALITY GRADES
New vehicles are fitted with tires
that have their Tire Quality Grade
(described below) molded into the
tire's sidewall. These Tire Quality
Grades are determined by standards
that the United States Department
of Transportation has set.
Tire Quality Grades apply to new
pneumatic tires for use on
passenger cars. They do not apply
to deep tread, winter-type snow
tires, space-saver or temporary use spare 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 Ford 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 one
and one-half (1 1/2) 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
The traction grades, from highest to lowest are AA, A, B, and C. Those
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.
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.
Temperature A B C
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. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the minimum required by
law.
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.

SERVICING YOUR TIRES
Checking the tire pressure
²Use an accurate tire pressure gauge.
²Check the tire pressure when tires are cold, after the vehicle has been
parked for at least one hour or has been driven less than 5 km (3
miles).
²Adjust tire pressure to recommended specifications found on the label
located on the passenger door panel.
Improperly inflated tires can affect vehicle handling and can fail
suddenly, possibly resulting in loss of vehicle control.
Tire rotation
Because your vehicle's tires perform different jobs, they often wear
differently. To make sure your tires wear evenly and last longer, rotate
them as indicated in the Scheduled Maintenance Guide. If you notice
that the tires wear unevenly, have them checked.
The following procedure applies to vehicles equipped with single rear
wheels, if your vehicle is equipped with dual rear wheels it is
recommended that only the front wheels be rotated (side to side).
²Four tire rotation

Replacing the tires
Replace the tires when the wear
band is visible through the tire
treads.
When replacing full size tires, never mix radial, bias-belted, or
bias-type tires. Use only the tire sizes that are listed on the tire
pressure decal. Make sure that all tires are the same size, speed rating,
and load-carrying capacity. Use only the tire combinations
recommended on the decal. If you do not follow these precautions,
your vehicle may not drive properly and safely.
Make sure that all replacement tires are of the same size, type,
load-carrying capacity and tread design (e.g., ªAll Terrainº, etc.),
as originally offered by Ford.
Maintenance and care
193

Do not replace your tires with ªhigh performanceº tires or larger
size tires.
Failure to follow these precautions may adversely affect the
handling of the vehicle and make it easier for the driver to lose
control and roll over.
Tires that are larger or smaller than your vehicle's original tires may also
affect the accuracy of your speedometer.
SNOW TIRES AND CHAINS
Snow tires must be the same size and grade as the tires you
currently have on your vehicle.
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 chains. If you need to use chains, it is recommended that steel
wheels (of the same size and specifications) be used as chains may chip
aluminum wheels.
Follow these guidelines when using snow tires and chains:
²Use only SAE Class S chains.
²Install chains securely, verifying that the chains do not touch any
wiring, brake lines or fuel lines.
²Drive cautiously. If you hear the chains rub or bang against your
vehicle, stop and re-tighten the chains. If this does not work, remove
the chains to prevent damage to your vehicle.
²If possible, avoid fully loading your vehicle.
²Remove the tire chains when they are no longer needed. Do not use
tire chains on dry roads.
²The suspension insulation and bumpers will help prevent vehicle
damage. Do not remove these components from your vehicle when
using snow tires and chains.
Maintenance and care
194

²Drive at reasonable speeds (traveling at 105 km /h [65 mph] uses 15%
more fuel than traveling at 88 km/h [55 mph]).
²Revving the engine before turning it off may reduce fuel economy.
²Use of the air conditioner or defroster may reduce fuel economy.
²Use of speed control (if equipped) may improve fuel economy. Speed
control can help maintain a constant speed and reduce speed changes.
You may want to turn off the speed control in hilly terrain as
unnecessary shifting between third and fourth gears may occur and
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 Specifications.
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
2 km/h [1 mpg] is lost for every 180 kg [400 lb] of weight carried).
²Adding certain accessories to your vehicle (for example bug
deflectors, rollover/light bars, running boards, ski/luggage racks) may
reduce fuel economy.
²To maximize the fuel economy, drive with the tonneau cover installed
(if equipped).
²Use of fuel blended with alcohol may lower fuel economy.
