Subaru Crosstrek Owners Manual: 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.

driving - overconfidence because
you are driving a vehicle with the
Vehicle Dynamics Control system
could easily lead to a serious accident.
CAUTION
Even if your vehicle is equipped
with Vehicle Dynamics Control
system, winter tires should be

Temperature A, B, C
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. Sustained high
temperature can cause the material

To increase the speed (by the "RES/ SET" switch)
Press the "RES/SET" switch to the "RES"
side and hold it until the vehicle reaches
the desired speed. Then, release the
switch. The vehicle speed at that moment
will be memorized and treated as the new
set speed.
