■Traction AA, A, B, C
The traction grades, from highest to lowest, are AA, 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
(straight ahead) traction tests and does not include cornering (turn-
ing) traction.
■Temperature A, B, C
The temperature grades are A (the hi ghest), B, and C, representing
the tire’s resistance to the generation of heat and its ability to dissi-
pate heat when tested under cont rolled 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 pas-
senger car tires must meet under the Federal Motor Vehicle Safety
Standard No. 109.
Grades B and A represent higher le vels of performance on the labo-
ratory test wheel than the minimum required by law.
Warning: The temperature grades for this tire are established for a
tire that is properly inflated and not overloaded.
Excessive speed, underinflation, or excessive loading, either sepa-
rately or in combination, can cause heat buildup and possible tire
failure.
