Consumer Information

“ National Traffic and Motor Vehicle
Safety Act of 1966” .
Uniform Tire Quality Grading
Relevant tire grade information on tire
flanks.
All passenger car tires must conform to
federal safety requirements in addition
to these grades.
Traction “A” , “ B” , “C”
The traction grades, from highest to
lowest, are “A ” , “ B” and “ C" and they
represent the tire's ability to stop on
wet pavement as measured under con­
trolled conditions on specified govern­
ment test surfaces of asphalt and con­
crete. A tire marked “C” may have poor
traction performance. Warning: The
traction grade assigned to this tire is
based on braking (straightahead) trac­
tion tests and does not include cor­
nering (turning) traction.
Temperature “A ” , “ B” , “C ”
The temperature grades of “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 condi­
tions 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” cor­
responds to a level of performance
which all passenger car tires must
meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades “ B”
and “A ” represent higher levels of per­
formance 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 ex­
cessive loading, either separately or in
combination, can cause heat buildup
and possible tire failure.
