The tread wear grade is a compara- The traction grades, from highest to
tive rating based on the wear rate of lowest, are AA, A, B and C. The
grades represent the tires ability to
stop on wet pavement as measured
under controlled conditions on spec-
ified government test surfaces of
asphalt and concrete. A tire marked
C may have poor traction perfor-
mance.
The temperature grade for this
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
tires failure.This can cause lo ss
of vehicle control and serious
injury or death.

conditions on a specified govern-

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. However, performance
may differ from the norm because of
variations in driving habits, service
practices and differences in road
characteristics and climate.
