Subaru Forester: Uniform tire quality grading standards / TRACTION AA, A, B, C
The traction grades, from highest to
lowest, are AA, A, B and C. Those
grades 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.
WARNING
The traction grade assigned to
this tire is based on straightahead
braking traction tests,
and does not include acceleration,
cornering, hydroplaning,
or peak traction characteristics.
The temperature grades are 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 conditions
on a specified indoor laboratory
test wheel...
