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...
Other information:
This light blinks if the vehicle is driven with
tires of differing diameters fitted on the
wheels or with an excessively low air
pressure in any of the tires.
WARNING
If the AWD warning light flashes,
promptly park in a safe location then
check whether all four tires are the
same diameter and whether any of
the tires has a puncture or has lost
air pressure for some other reason...
