SENSORY MISALIGNMENT SIPING

摘要

A wear detection system for truck steer tires is provided. A plurality of sipe groups are located in a tread rib of the tire. Each sipe group includes a first sipe group portion having an axially inward directed apex and a second sipe group portion having an axially outwardly directed apex, such that an axially directed wear force component causes the apex of the sipe group directed in the direction of the wear force component to be more tactilely detectable by a human fingertip than the apex of the other sipe group portion.
