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...

WARNING
Never turn the ignition switch to
the “LOCK” position while the
vehicle is being driven or towed
because that will lock the steering
wheel, preventing steering
control. And when the engine is
turned off, it takes a much greater
effort than usual to steer...
New transmitters can be programmed to
the remote engine start system in the
event that a transmitter is lost, stolen,
damaged or additional transmitters are
desired (the system will accept up to eight
transmitters). New remote engine start
transmitters can be programmed according
to the following procedure...
