C onsum er Inform ation
This has been prepared as re­
quired of all m anufacturers of
passenger cars under Title 49,
Code of U.S. Federal Regulations,
Part 575 pursuant to the “ National
Traffic and M otor V ehicle Safety
Act of 1966” .
Uniform Tire Quality Grading
Refer to the tire sidew all for the
specific tire grades for the tires with
which this vehicle is equipped.
All passenger car tires m ust co n ­
form to federal safety requirem ents
in addition to these grades.
Treadw ear
The treadw ear grade is a com ­
parative rating based on the w ear
rate of the tire when tested under
controlled conditions on a specified
governm ent test course. For exam ­
ple, a tire graded 150 would w ear
one and one-half (1 1/ 2 ) tim es as
well on the governm ent course as
a tire graded 100. The relative perf­
orm ance of tires depends upon the
actual conditions of their use, how ­
ever, and may depart significantly
from the norm due to variations in
driving habits, service practices
and differences in road ch aracte r­
istics and clim ate.
Traction
The traction grades, from highest
to lowest, are AA, A, B, and
C.
Those grades represent the tire ’s
ability to stop on w et pavem ent as
m easured under controlled co n d i­
tions on specified governm ent test
surfaces of asphalt and concrete.
A tire m arked
C m ay have poor
traction perform ance.
controlled conditions on a specified
indoor laboratory test wheel.
Sustained high tem perature can
cause the m aterial of the tire to
degenerate and reduce tire life,
and excessive tem perature can
lead to sudden tire failure. The
grade C corresponds to a level of
perform ance which all passenger
car tires m ust m eet under the
Federal M otor Vehicle Safety
Standard No. 109. G rades B and A
represent higher levels of
perform ance on the laboratory test
w heel than the m inim um required
by law.
W arning!
The traction g rade assigned to
this tire is based on straig h t­
ahead braking traction tests,
and does not include accelera­
tion, cornering, hydroplaning,
or peak traction characteristics.
Tem perature
The tem perature grades are A (the
highest), B, and C, representing
the tire ’s resistance to the gen era ­
tion of heat and its ability to
dissipate heat w hen tested under
W arning!
The tem perature 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
com bination, can cause
excessive heat build up and
possible tire failure.
