Replacing the Tires
*
[MC18900(ALL)01/96]

Information About Tire Quality Grades
*
[MC19900(ALL)01/96]
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.
*
[MC20000(ALL)01/96]
Tire Quality Grades apply to new pneumatic tires for use on
this vehicle. 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 (254-305 mm) or
limited production tires as defined in Title 49 Code of Federal
Regulations Part 575.104(c)(2).
*
[MC20100(ALL)01/96]
U.S. Department of Transportation Ð 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.
%*
[MC20200(ALL)01/96
]
Treadwear
*
[MC20300(ALL)01/96]
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 A B C
*
[MC20500(ALL)01/96]
The traction grades, from highest to lowest, are A, B, and C,
and they 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. Warning: The traction grade assigned
to this tire is based on braking (straight ahead) traction tests
and does not include cornering (turning) traction.
*
[MC20600(ALL)01/96]
Temperature A B C
[MC20700(ALL)01/96]
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 Stadard No. 109. Grades B and
A represent higher levels of performance on the laboratory test
wheel than the minimum required by law. 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.
%*
[MC20800(ALL)01/96
]
Snow Tires and Chains
*
[MC20900(ALL)03/96]
The tires on your vehicle have all-weather treads that provide
traction in rain or snow. However, during the winter months in
some climates, you may need to use snow tires and occasionally
chains for your tires.

Choosing the Right Fuel
*
[MC24200(ALL)03/96]
Use only UNLEADED FUEL. Using leaded fuel is prohibited by
federal law and could damage your vehicle. The damage may
not be covered by your warranty.
*
[MC24300(ALL)05/96]
Vehicle inspection programs may detect misfueling. Under these
circumstances, you may be required by law to make costly
repairs at your own expense.

Octane recommendation
*
[MC24500(ALL)03/96]
Your vehicle is designed to use regular unleaded gasoline with
an (R+M)/2 octane rating of 87. We do not recommend
gasolines labeled ªregularº in high altitude areas that are sold
with octane ratings of 86 or even less.
