Abstract: Methods, apparatuses, computer program products, systems for enhanced tracking of tire tread wear are disclosed. In a particular embodiment, a tire monitoring sensor (TMS) detects a tread wear reporting event, generates tread wear data including at least a rotational time period, and transmits the tread wear data to a vehicle control system (VCS). The rotational time period may be a measure of time the tire takes to complete a particular number of revolutions. The VCS receives, from the TMS, the tread wear data including at least the rotational time period, determines a current circumference of the tire based on at least the rotational time period, and determines a tread wear value based on at least the current circumference.

Abstract: Determining tread depth using data from a tire mounted sensor (TMS), including: determining, based on data collected by the tire mounted sensor, a tire deformation for a tire; determining, based on the tire deformation, an effective rolling radius of the tire; and determining, based at least on the effective rolling radius of the tire, an estimated tread depth for the tire.
