Consumer information
The following text is published as required
of all manufacturers of passenger cars un-
der Title 49, Code of U.S. Federal Regula-
tions, Part 575 pursuant to the “National
Traffic and Motor Vehicle Safety Act of
1966”.Uniform tire quality grading
Quality grades can be found, where appli-
cable, on the tire sidewall between tread
shoulder and maximum section width. For
example:
All passenger car tires must conform to
federal safety requirements in addition to
these grades.Tread wear
The tread wear grade is a comparative rat-
ing based on the wear rate of the tire when
tested under controlled conditions on a
specified government test course. For ex-
ample, a tire graded 150 would wear one
and one-half (1½) times as well on the gov-
ernment 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
The traction grades, from highest to lowest
are AA, A, B, and C. Those grades repre-
sent the tire’s ability to stop on wet pave-
ment as measured under controlled
conditions on specified government test
surfaces of asphalt and concrete. A tire
marked C may have poor traction perfor-
mance.Tread wear

characteristics.

Distronic will reduce your vehicle
speed to the extent permitted by re-
duced throttle and up to 20% brak-
ing power to maintain the preset
minimum following distance.

Measurement for the inner friction (vis-
cosity) of the oil at different tempera-
tures. The higher the temperature an
oil can tolerate without becoming thin,
or the lower the temperature it can tol-
erate without becoming viscous, the
better the viscosity.

line as determined by a standardized
method. It is an indication of a gaso-
line's ability to resist undesired detona-
tion (knocking). The average of both
