Abstract: Systems and methods are disclosed herein for monitoring tire aging with respect to a motor vehicle and/or across vehicle fleets. A computing device (e.g., cloud server) is linked to vehicle-mounted data acquisition devices which provide signals corresponding to ambient temperature and contained air temperatures for respective tires. The computing device ascertains oxidative aging characteristics for the tires, based on at least the collected ambient temperature and respective contained air temperature, and respective rates of accumulation thereof with respect to time and/or distance traveled, and further ascertains the oxidative aging characteristics for each tire with respect to a fixed reference ambient temperature, and respective rates of accumulation thereof with respect to time and/or distance traveled. Selectively generated output signals correspond to monitored characteristics and respective rates of accumulation thereof for the respective tires. The oxidative aging characteristics may for example be ascertained at least in part via Arrhenius reaction rate integration.

Abstract: A real time tire pressure sensing system includes sensors to collectively generate signals corresponding to a contained tire air temperature, a contained inflation pressure, and an ambient temperature associated with a tire mounted on a vehicle. A processor determines an effective tire inflation pressure based on the generated signals and further at least on a calculated moving average of the ambient temperature (e.g., over a defined time period such as 24 hours) and generates real time notifications associated with the determined effective tire inflation pressure to specified user interfaces. At least one sensor may be an inflation pressure sensor configured to generate event-based signals corresponding to detected changes per unit pressure. The processor may further generate real time feedback control signals to an automatic tire inflation device, based on the determined effective tire inflation pressure, or enable and prompt manual control of the tire inflation device via the user interface.

Abstract: A tire having an indicator device that visually indicates exposure of the tire to a pre-selected temperature is provided, and an indicator device that may be positioned on a tire, for indicating that the tire has been exposed to a pre-selected temperature. The device includes expandable graphite dispersed within a pouch or binder. Also described is a method for detecting that a tire has been exposed to excessive temperature. The method includes providing a tire that includes at least one indicator device that contains a pouch or binder and expandable graphite dispersed in the pouch or binder. Visual inspection of the tire to detect a change in the appearance, shape, volume or texture of the indicator device can indicate that the tire has been exposed to a temperature that meets or exceeds a pre-selected temperature.
