tions of their use and may vary due to driving habits, service prac-
tices, differences in road characteristics, and climate.
• Traction - The traction grades from highest to lowest are AA, A, B,
a
nd 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.
• Temperature - The temperature grades are A (the highest), B, and C,
r
epresenting 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 tempera -
tures can cause the materials of the tire to degenerate and reduce tire
li
fe, and excessive temperature can lead to sudden tire failure. The
grade C corresponds to a level of performance that all passenger car
tires must meet under the Federal Motor Vehicle Safety Standard
No. 139. Grades B and A represent higher levels of performance on
the laboratory test wheel than the minimum required by law.
• D OT Quality Grades - All passenger car tires must conform to
f
ederal requirements in addition to these grades. CAUTION!
The traction grade assigned to tires is based on locked braking
( s
traight ahead) traction tests and does not include cornering
(turning) traction.
WARNING!
The temperature grade is established for a tire that is properly
in
flated and not overloaded. Excessive speed, underinflation, or
excessive loading either separately or in combination can cause
heat buildup and possible tire failure. This can cause an accident,
which could lead to serious personal injury or death.
