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...

Certification label
The certification label attached to the
bottom of driver’s side door pillar shows
GVWR (Gross Vehicle Weight Rating) and
GAWR (Gross Axle Weight Rating).
The GVW (Gross Vehicle Weight) must
never exceed the GVWR. GVW is the
combined total of weight of the vehicle,
fuel, driver, all passengers, luggage, any
optional equipment and trailer tongue
load...
To help prevent moisture from forming in
the fuel system and the risk of its freezing,
use of an antifreeze additive in the fuel
tank is recommended during cold weather.
Use only additives that are specifically
designed for this purpose. When an antifreeze
additive is used, its effect lasts
longer if the tank is refilled whenever the
fuel level reaches half empty...
