system to not function during a hard braking
event. This could cause an accident or serious
personal injury. Use the table below to determine
the acceptable range of tire rev/mile.
For proper ABS operation all tire sizes must be within the
appropriate range listed below. A change of tire size may
require that the ABS ECU be changed based on the listed
