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
a 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
The traction grades, from highest to lowest are: A, B, and C. 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.
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.
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.
Those grades are molded on the sidewalls of passenger car tires.

Downloaded from www.Manualslib.com manuals search engine This transaxle is the first of a new generation of “SMART” transmissions.
The computer which controls the electronic shift solenoids adapts to
changing environments while you drive. This provides consistent high
quality shifts under all conditions. Communication between the engine
and transaxle through this computer controls engine output during
activation
of torque management or traction control. Smooth shifting is
ensured by design. Hydraulic accumulators control shift pressures and all
shifts are made to free wheeling elements.
The 4T80E uses a
dry sump lubrication system with a scavenger pump.
This unique feature enables the transaxlc to maintain itdcqlriltt!
pressurized oil supply during all mancl~vcr\.
