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.

A tire data information system includes at least one tire that supports a vehicle and a processor. At least one sensor is mounted on the tire and is in electronic communication with the processor. The sensor measures a temperature and a pressure of the tire. A memory for storing tire identification information is in electronic communication with the processor. A tire wear state estimator generates a wear state of the tire and is in electronic communication with the processor. A tire wear rate estimator generates a wear rate of the tire and is in electronic communication with the processor. An antenna transmits the temperature, pressure, identification information, wear state, and wear rate of the tire to a display device that is accessible to a user of the vehicle. The display device includes indicators for showing the temperature, pressure, identification information, wear state, and wear rate to the user.

A tire having a contact face of a width TW is provided. The contact face is intended to come into contact with ground during rolling. The tread is provided with at least one groove of a depth D provided with a wear indicating means that extends generally in a circumferential orientation and opens to the contact face. The tread comprises a center region and a pair of shoulder regions that are positioned on two axial sides of the center region. The shoulder regions each comprise a shoulder rubber layer of a thickness ts made of a shoulder rubber composition different from a rubber composition constituting the tread. A shear storage modulus G′ of the shoulder rubber composition measured at 23° C., 10 Hz and 10% of strain is less than or equal to 1.0 MPa.

The aim of the disclosed solution is to present a method of inserting an insert to a tread a tire such that the insert, particularly a fragile insert such as an insert comprising electronic components, may be protected against gripping and impact forces during its insertion. The disclosed solution is premised on an insert being housed, at least partially, in a sleeve upon and during its installation to a tread of a tire. Thus, the sleeve may be employed to provide protection for the insert against gripping and/or impact forces during the insertion of the insert into the tread a tire.

A wear computing system (100, 200, 300) for computing a wear of a wheel (3) of a vehicle (2) comprises a revolution sensor (48) configured to detect a number of revolutions of the wheel (3), an acceleration sensor (49) configured to detect an acceleration of the vehicle (2) in a travel direction thereof, and a control unit (7) configured to compute a travel distance of the vehicle from the acceleration of the vehicle, and compute the wear from the travel distance and the number of revolutions of the wheel (3).

A drive-through vehicle inspection system acquiring information from engraved markings on the tire sidewalls of a moving vehicle. Optical imaging sensors disposed on opposite sides of the vehicle acquire images of the sidewall surfaces for each passing wheel assembly. The acquired images are evaluated by a processing system configured to identify, within the acquired images, visible markings engraved into the tire sidewall surfaces which include at first portion having a first optical reflectivity, and a second portion having a second optical reflectivity which is different from the first optical reflectivity. Each identified marking is decoded to retrieve data stored therein, representative of the tire, wheel assembly, and/or associated vehicle onto which the wheel assembly is installed. The retrieved data is incorporated into an inspection report and/or utilized by the vehicle inspection system to access vehicle-specific information contained within an indexed database.

A component life prediction system configured to predict the remaining life of a consumable component installed on an aircraft. The system includes a processor configured to: receive wear information indicative of a current wear state of the component; receive schedule information indicative of a future flight schedule for the aircraft; and determine the remaining life of the component based on the received wear information and the received schedule information.
