Avoid wheelspin. This can lead to damage
to the drive train.
The traction grades, from highest to lowest,
are AA, A, B and C. These grades represent the
tire's ability to stop on wet surfaces, as
measured under controlled conditions on
specified government test surfaces of
asphalt and concrete. A tire marked C may
have poor traction performance.
The safe speed on a wet, snow covered or icy
road is always lower than on dry road sur-
faces.
The drivers must pay special attention to
road conditions when temperatures are
around freezing point.
smart recommends a minimum tread depth of
ã
in (4 mm) on all four winter tires. The
legally required minimum tread depth must
be observed. Winter tires can reduce the
braking distance on snow-covered surfaces
in comparison with summer tires. The brak-
ing distance is still much further than on
surfaces that are not icy or covered with
snow. Therefore take appropriate care when
driving.

WARNING
The temperature grade for this tire is
established for a tire that is properly
inflated and not overloaded. Excessive
speed, underinflation, or excessive load-
ing, either separately or in combination,
can cause excessive heat build-up and
possible tire failure.
The temperature grades are A (the highest), B
and C. They represent the tire's resistance to
the generation of heat and its ability to dis-
sipate 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 tempera-
ture 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. 109. Grades B and A represent
higher levels of performance on the labora-
tory test wheel than the minimum required
by law.

WARNING
Exceeding the stated tire load-bearing
