Described herein are systems and methods for determination of rolling resistance from a sensor or sensors in a tire or tires for application in smart cars to provide feedback to interested parties, such as Departments of Transportation or tire manufacturers.

The embodiments described herein generally relate to an electronic communication module suitable for incorporating into a tire or tire retread, where the electronic communication module comprises a radio device having at least a portion of its outer surface surrounded by a rubber composition. Certain embodiments also relate to tires or tire retreads containing the electronic communication module. In addition, certain embodiments relate to methods for improving the readability of a radio device incorporated into a tire or tire retread.

A chemically treated, RFID equipped mesh tire label configured to be integrally incorporated within a vulcanized tire and to provide unique identifier(s) and/or other information about the vulcanized tire during and post tire vulcanization, the label comprising: a mesh face layer configured to be adhered to an outer surface of an unvulcanized tire; a mesh backing layer attached to the mesh face layer and adapted to be integrally incorporated in a vulcanized tire after subjecting a green tire to a vulcanization process; and an RFID device affixed between the mesh face and mesh backing layers, the RFID device that is configured to provide unique identifier(s) and/or other information upon being read with an RFID reader during and post tire vulcanization.

An intelligent tire monitoring system includes a tire body, a sheet-shaped conductive polymer sensor, a micro control unit, an RF unit, a computer, and an RF circuit. The sheet-shaped conductive polymer sensor is affixed to an inner liner layer at a middle portion of a tire crown. One end of the sheet-shaped conductive polymer sensor is connected to the micro control unit through the RF unit, and the other end of the sheet-shaped conductive polymer sensor is connected to the computer through the RF circuit. The computer includes a power supply module, a communication port, a display screen, an audible alarm, a press-key input module, and a processor. The state of the tire is comprehensively determined by matching or combining a strain amplitude of the tire crown and an operating temperature with a fitting function.

A pneumatic tire (1) having: a toroidal carcass (2), which is comprised of a body ply (3) partially collapsed onto itself and therefore having two lateral flaps; two annular beads (4), each of which is surrounded by the body ply (3) and has a bead core (5) and a bead filler (6); an annular tread (7); a pair of sidewalls (11) arranged externally to the body ply (3) between the tread (7) and the beads (4); a pair of abrasion gum strips (12) arranged externally to the body ply (3) under the sidewalls (13) and at the beads (4); and a transponder (13) which is arranged in contact with the body ply (3) at a flap of the body ply (3) and is located below an edge (19) of the body ply (3) between the edge (19) of the body ply (3) and the bead (4).

An RFID mesh label configured to be integrally incorporated within a vulcanized tire and to further provide unique identifier(s) and/or other information about the vulcanized tire during and/or post-vulcanization, the RFID mesh label including a face layer configured to be positioned adjacent or flush to an outer surface of the vulcanized tire; an RFID layer positioned underneath the face layer, the RFID layer having an RFID device that is configured to provide unique identifier(s) and/or other information about the vulcanized tire upon being read with an RFID reader; and a mesh backing overlying the RFID layer and adapted to be integrally incorporated in a vulcanized tire after subjecting a green tire to a vulcanization process.

A tire suitable for running flat comprises a crown, two sidewalls and two beads, a carcass reinforcement with at least one carcass ply anchored in each bead and a sidewall insert placed axially internally relative to at least the carcass ply, wherein the tire is equipped with an electronic device comprising at least one radiofrequency transponder and wherein, each bead comprising a bead wire of revolution about a reference axis and H being one of the points of the bead wire closest to the axis of revolution, the electronic device is placed axially in a zone of the tire bounded by at least one of the beads and one of the sidewalls and radially externally at a radial distance larger than 20 mm from the point H.

An RFID mesh label configured to be integrally incorporated within a vulcanized tire and to further provide unique identifier(s) and/or other information about the vulcanized tire during and/or post-vulcanization, the RFID mesh label including a face layer configured to be positioned adjacent or flush to an outer surface of the vulcanized tire; an RFID layer positioned underneath the face layer, the RFID layer having an RFID device that is configured to provide unique identifier(s) and/or other information about the vulcanized tire upon being read with an RFID reader; and a mesh backing overlying the RFID layer and adapted to be integrally incorporated in a vulcanized tire after subjecting a green tire to a vulcanization process.

A tire integrated with an electronic device includes the electronic device attached to an inner liner or a side wall of the tire by vulcanization. The electronic device is attached to an inner side or an outer side of an end of a bead filler depending on a length of the bead filler not to reduce durability of the tire.

A chemically treated, RFID equipped mesh tire label configured to be integrally incorporated within a vulcanized tire and to provide unique identifier(s) and/or other information about the vulcanized tire during and post tire vulcanization, the label comprising: a mesh face layer configured to be adhered to an outer surface of an unvulcanized tire; a mesh backing layer attached to the mesh face layer and adapted to be integrally incorporated in a vulcanized tire after subjecting a green tire to a vulcanization process; and an RFID device affixed between the mesh face and mesh backing layers, the RFID device that is configured to provide unique identifier(s) and/or other information upon being read with an RFID reader during and post tire vulcanization.
