Operation
In a collision, the force of the impact is measured by the impact sensors,
pressure sensors and the RCM internal
accelerometer. The RCM evaluates the readings to determine the impact point on
the vehicle. The RCM also
determines if the readings exceed the limits for firing any of the airbags and
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

on the government course as a tire graded
100.
