a cloth or a paper towel
to do this; but be sure to use
a scraper or wire

Traction -- A, B, C
The tmction 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 perf’ormance.
Wxning: The traction grade assigned
to this tire is based
on braking (straight ahead) traction tests and does not
include cornering (tuning) traction.
Temperature -- A, B, C
The temperature grades are A (,the highest), B, and C.
representing the tire‘s resistance to the gencration of
heat and its ability to dissipate heat when tested undcr
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. 109. Grades B and A represent higher levels of
performance
on the laboratory test wheel than the
minimum required
by law.
Warnin?: Thc ten~perat~u-e pxde for this tire is
estnblishcd for a tire that is properly intlated and not
overloaded. Excessive speed. underinflation, or
excessive loading. either separatcly or in combination.
