TREAD WEAR
TEMPERATURE-A, B AND C
The temperature grades are A (the
highest), B and C, representing the tire’s
resistance to generate heat and to
dissipate heat when tested under
controlled conditions on a specified
indoor laboratory test wheel. Sustained
high temperatures can cause the material
of the tire to degenerate and reduce tire
life, and excessive temperature can lead
to sudden tire failure. Grade C
corresponds to a level of performance
that all passenger vehicle tires must meet
under the Canadian Motor Vehicle
Safety Standard No. 109: Grades A and
B represent higher levels of performance
on the laboratory test wheel than the
maximum required by law.
WARNING - Tire
Temperature
The tread wear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled conditions
on a specified government test course.
For example, a tire graded 150 would
wear one-and-a-half times as well on the
government course as a tire graded 100.
The relative performance of tires
depends upon the actual conditions of
their use. Variations in driving habits,
service practices and differences in road
The temperature grade for a 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
build-up and possible sudden tire
failure. This can cause loss of
vehicle control and death or
personal injury.
characteristics
and climate may
significantly affect performance.
TRACTION - A, B AND 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 controlled
conditions on specified government test
surfaces of asphalt and concrete. A tire
marked C may have poor traction
performance.
