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.

[SV28399(ALL)01/95]
Treadwear
*
[SV28400(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
*
[SV28500(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
*
[SV28700(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
*
[SV29000(ALL)01/95]
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.

RWARNING
Snow tires must be the same size and
grade as the tires you currently have on
your vehicle.
