Regulations, Part 575 pursuant to the

Uniform Tire Quality Grading
Relevant tire grade inform ation on tire
flanks.
All passenger car tires m ust conform
to federal safety requirem ents 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 w et pavement as measured under
controlled conditions on specified
governm ent test surfaces of asphalt
and concrete. A tire marked " C " may
have poor traction performance.
W arning: The traction grade assigned
to this tire is based on braking
(straightahead) traction tests and
does not include cornering (turning)
traction.
Temperature " A " , " B " , " C "
The tem perature 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 tem pera
ture can cause the material of the tire
to degenerate and reduce tire life, and
excessive tem perature can lead to
sudden tire failure. The grade " C "
corresponds to a level of perform
ance which all passenger car tires
m ust meet under the Federal M otor
Vehicle Safety Standard No. 109.
Grades " B " and " A " represent higher
levels of perform ance on the labora
tory test wheel than the minimum
required by law. Warning: The tem
perature grade fo r this tire is estab
lished fo r a tire that is properly
inflated and not overloaded. Exces
sive speed, underinflation, or exces
sive loading, either separately or in
com bination, can cause heat buildup
and possible tire failure.
