characteristics and climates.
Traction - AA, A, B, C:
The traction grades, from highest
to lowest are: AA, A, B, and C. They represent the tires
ability to stop on wet pavement as measured under con-
trolled 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 acceleration, cornering, hydroplaning, or
peak traction characteristics.
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 fail-
ure. The grade ‘C’ corresponds to a level of performance
which all passenger car Tires must meet under Federal
Motor Car 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 load-
ing, either separately or in combination, can cause
heat buildup and possible tire failure.
These grades are moulded onto the sidewalls of pas-
senger car tires. All passenger car tires must conform to
Federal safety requirements in addition to these grades.
