Traction AA A B C
WARNING
The traction grade assigned to
this tire is based on
straight-ahead braking traction
tests, and does not include
acceleration, cornering,
hydroplaning or peak traction
characteristics.
The traction grades, from highest to
lowest are AA, A, B, and C. The
grades 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.
Temperature A B C
WARNING
The temperature 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 combination,
can cause heat buildup and possible
tire failure.
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
failure. The grade C corresponds to
a level of performance which 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.
Glossary of Tire Terminology
• Tire label: A label showing the
original equipment tire sizes,
recommended inflation pressure
and the maximum weight the
vehicle can carry.
• Tire Identification Number: A
number on the sidewall of each
tire providing information about
the tire brand and manufacturing
plant, tire size and date of
manufacture. Also referred to as
DOT code.
• Inflation pressure: A measure
of the amount of air in a tire.
