The invention relates to a method for determining a wheel load (WL) acting on a tire (1) of a vehicle, comprising: a) determining a footprint (L) of the tire (1), b) receiving a tire information (ti) that identifies a type of the tire (1) and/or characterizes physical properties of the tire (1) as such, c) receiving tire operation conditions (toe) based on a measurement, d) selecting one of a plurality of predetermined calculation models (mod(ti)) based on the received tire information (ti), wherein each of the predetermined calculation models (mod(ti)) defines the wheel load (WL) as a function of the footprint (L) and the tire operation conditions (toe) for a respective tire type and/or respective physical properties of the tire (1) as such, e) calculating the wheel load (WL) based on the determined footprint (L) and the received tire operation conditions (toe), using the selected calculation model (mod(ti)). Further, a corresponding system (10) for determining a wheel load (WL) is proposed. Advantageously, the invention can be employed very universally and can deal with the problem of varying tire characteristics.

A tire includes a plurality of tire components defining a plurality of layers. A radio frequency identification (RFID) tag is disposed between at least two of the plurality of layers. The RFID tag is in contact with each of the at least two layers and is configured to transmit a response signal in response to receiving a request signal. When no air is in a region surrounding the RFID tag, a first response signal is emitted from the tire at a first frequency and first power. However, when air is in the region surrounding the RFID tag, a second response signal is emitted from the tire at the first frequency and a second power different from the first power.

A rubber article having an electronics attachment mechanism is provided. In one embodiment, the rubber article is a tire, comprising: a tread surface; an inner surface; and a tire body contained between the tread surface and the inner surface; wherein the tire body comprises a cavity having a cavity major width in at least one of an axial direction and a circumferential direction, wherein a channel extends between the cavity and the inner surface, wherein the channel has a channel major width in at least one of the axial direction and the circumferential direction, and wherein the cavity major width is greater than the channel major width.

A rubber article having an electronics device fastener is provided. In one embodiment, a tire is provided, the tire comprising: a first surface; a second surface; and a tire body contained between the first surface and the second surface; wherein the tire body comprises a cavity having a cavity major width in at least one of an axial direction and a circumferential direction, wherein a channel extends between the cavity and the first surface, wherein the channel has a channel major width in at least one of the axial direction and the circumferential direction, wherein the cavity major width is greater than the channel major width, and wherein a protrusion of a fastener is engaged within the cavity.

An inflatable electronics band for use in a tire features an annular, flexible, inflatable, tubular body configured to contact an inner portion of a tire opposite the tread surface, such as an innerliner. The inflatable electronics band further features an inflation valve, disposed on the tubular body. The tubular body is configured to inflate to a pressure at least 10% greater than the recommended tire inflation pressure.

An assembly for mounting an electronics package to an interior of a tire includes a carriage configured to receive an electronics package. The assembly also includes an attaching device having a first side and a second side. The first side of the attaching device is permanently affixed to the interior of the tire. The second side of the attaching device has an attaching structure. The attaching structure is configured to receive the carriage to form a secure and locked connection.

A long-distance radio frequency electronic identification tire structure is provided. When the production of the tire is completed and an electronic tag reading device is used for identification, an RFID chip of an ultra high frequency electronic tag of a main tire body receives and sends an electromagnetic wave signal generated by a far-field copper film antenna and the electronic tag reading device. The frequency band and the bandwidth of the electromagnetic wave signal are adjusted by a frequency band/bandwidth adjustment portion, and first and second field effect adjustment grooves of first and second field effect adjustment portions are configured to adjust the field effect when a tire bead bundle and a steel belt layer reflect the electromagnetic wave signal, so that the electronic tag reading device can read the identification code of the ultra high frequency electronic tag at a wide angle and a long distance.

A tire monitor includes a sensor generating tire data. The tire monitor is configured to wake in response to a low frequency interrupt signal received from a remote source. Upon waking, the tire monitor scans Bluetooth Low Energy (BLE) channels to establish a BLE connection with the remote source. The tire monitor communicates with the remote source over the BLE connection.

Provided is a tire information acquisition device. A sensor unit substrate on which a sensor for acquiring tire information and a power supply unit for supplying electric power to the sensor are disposed is provided, and a heat-insulating material is disposed at at least a periphery of the power supply unit.
