Subaru Forester: Uniform tire quality grading standards / TREADWEAR
The treadwear grade is a comparative
rating based on the wear rate of
the tire when tested under controlled
conditions on a specified
government test course.
For example, a tire graded 150
would wear one and one-half (1-
1/2) 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, and may
depart significantly from the norm
due to variations in driving habits,
service practices and differences in
road characteristics and climate.
This information indicates the relative
performance of passenger car
tires in the area of treadwear,
traction, and temperature resistance.
This is to aid the consumer
in making an informed choice in the
purchase of tires.
Quality grades can be found where
applicable on the tire sidewall betw..
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...
Other information:
The performance and long life of your
vehicle are dependent on how you handle
and care for your vehicle while it is new.
Follow these instructions during the first
1,000 miles (1,600 km):
Do not race the engine. And do not
allow engine speed to exceed 4,000 rpm
except in an emergency...
While the light control switch is in the
“AUTO” position, the headlights will automatically
turn on when the windshield
wipers operate several times. The headlights
will automatically turn off when the
wipers stop.
NOTE
