Information About Tire Quality Grades
*
[SV27500(ALL)01/95]
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.
*
[SV27550(ALL)01/95]
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 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.

Treadwear
*
[SV27800(ALL)01/95]
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
*
[SV28000(ALL)01/95]
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 (straightahead) traction tests and
does not include cornering (turning) traction.

Temperature A B C
*
[SV28300(ALL)01/95]
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. 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.

Snow Tires and Chains
*
[SV28601(ALL)06/93]
During the winter months in some climates, you may need to
use snow tires and occasionally chains for your tires.
*
[SV28700(ALL)05/95]
RWARNING
Snow tires must be the same size and grade as the tires
you currently have on your vehicle.
*
[SV28750(ALL)02/95]
Use chains on the tires only in an emergency or if the law
requires them where you live. If you choose to use chains on
your vehicle's tires, be aware of the following:
*
[SV28801(ALL)11/94]
n
Tire chains may scratch or chip aluminum wheels. IT IS
RECOMMENDED THAT TIRE CHAINS ARE INSTALLED
ON STEEL WHEELS ONLY. Be sure to remove wheel
covers (if equipped) from steel rims before using tire chains
to avoid scratches or damage.
