wheel FORD MUSTANG 1998 4.G Owner's Manual

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
Maintenance and care
150

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 tire pressure label
inside the glove compartment door.
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 Schedule maintenance guide. If you notice
that the tires wear unevenly, have them checked.
Maintenance and care
151

Tires that are larger or smaller than your vehicle's
original tires may also affect the accuracy of your
speedometer.
SNOW TIRES AND CHAINS
Driving too fast for conditions creates the
possibility of loss of vehicle control. Driving
at very high speeds for extended periods of time
may result in damage to vehicle components.
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. Use chains on the tires only in an emergency
or if the law requires them.
Follow these guidelines when using snow tires and
chains:
²Chains may damage aluminum wheels.
²Use only Cable Type chains with size P225/55R16
or 245/45ZR17 tires. Use of SAE Class S chains
may damage vehicle.
²SAE Class S chains may be used on P205/65R15
tires.
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.
Maintenance and care
153

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.
²Use of 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.
²Flat terrain driving improves fuel economy over
hilly roads.
²Transmissions give their best fuel economy when
operated in the top cruise gear and with steady
pressure on the gas pedal.
²Close windows for high speed driving.
Maintenance and care

windshield as described inCleaning the wiper
blades and windshield.
Repairing paint chips
Minor scratches or paint damage from road debris
may be repaired with touch-up paint, repair foil or
aerosol paint spray from the Ford accessory line.
Observe the application instructions on the
products.
Remove particles such as bird droppings, tree sap,
insect remains, tar spots, road salt and industrial
fallout immediately.
Cleaning the wheels
Wash with the same detergent as the body of your
vehicle. Do not use acid-based or alcohol-based
wheel cleaners, steel wool, fuel or strong detergents.
Never use abrasives that will damage the finish of
special wheel surfaces. Use a tar remover to remove
grease and tar.
Cleaning the engine
Engines are more efficient when they are clean
because grease and dirt buildup keep the engine
warmer than normal. When washing:
²Take care when using a power washer to clean
the engine. The high pressure fluid could
penetrate the sealed parts and cause damage.
²Do not spray with cold water to avoid cracking
the engine block or other engine components.
