Abstract
The disclosed technology includes a system comprising a tire-mounted inertial measurement unit (IMU). The IMU can be configured to measure linear acceleration data and angular velocity data associated with a tire, and the system can be configured to determine various indicators of tire health based on the linear acceleration data and angular velocity data. The system can be configured to determine a distance between the IMU and an outer rolling surface of the tire. The system can be configured to monitor changes in this distance over time, which can be indicative of tread wear over time. Accordingly, the system can be configured to monitor change in the tread depth over time such that the system is configured to monitor tread depth of the tire.
