A tire or tire tread features a helical, metallic RFID tag antenna, configured to provide an operable frequency response between 900 and 930 MHz upon receiving 100 electromagnetic waves having a power between 12 and 24 dBm. The helical, metallic RFID tag antenna is disposed within the at least one tread feature and has a wear rate commensurate with a wear rate of the at least one tread feature. The response(s) from the helical, metallic RFID tag antenna are used to track tread wear.

The present invention provides an RFID tag and a processing method for an RFID tag. The RFID tag is mainly applied to a rubber product. The RFID tag includes: a substrate, a chip and an antenna; a chip is arranged on a substrate, wherein the chip has a predetermined code thereon to enable a reader to identify; an antenna, in which the antenna is in a communication connection with a chip, and is configured for transmitting a radio frequency signal between the chip and a reader; the substrate is further provided with a connecting part, and the antenna is connected to the substrate through the connecting part. The RFID tag in the present invention solves the problem in the related art that a substrate in a RFID tag is not reliably connected to an antenna.

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 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 pneumatic tire comprises a first sound damper fixed to a tire inner surface and being made of a sponge material; a second sound damper disposed on a tire internal space side of the first sound damper, and being made of a sponge material; and a communication device retained between the first sound damper and the second sound damper. The second sound damper has a hardness in a range of greater than 25N and no greater than 55N. The first sound damper has a hardness in a range of no less than 25N and less than 55N. The hardness of the second sound damper is greater than the hardness of the first sound damper. The hardness is measured in accordance with the Method A in Section 6.4 of the test methods as defined under the Hardness Tests in Section 6 of JIS K6400-2 (2012).

Methods for increasing the read range of an electronic communication module within a tire and methods for improving the read range of an electronic communication module within a tire are provided herein. As discussed further herein, the read range can be improved by applying strain to the tire without circumferentially contacting the outer surface of its tread, resulting in an increase in the same-distance-signal-strength of 5% or more. Also provided are tires made according to the disclosed methods.

Disclosed are pre-cure RFID-enabled bead labels based on an RFID inlay construction consisting of an aluminum antenna etched on to a high temperature resistant polyimide film that is connected to an integrated memory circuit positioned on the surface of the polyimide film. This RFID inlay being further inserted into an overall label construction having a plurality of layers that include, for example, a plurality of polyester layers and a plurality of high temperature resistant adhesive layers that bond/adhere layers together, the plurality of layers further protecting and insulating the RFID inlay while the label is bonded to the external bead (or sidewall) of a tire. The compositions/devices disclosed herein can be used for electronic identification when applied on rubber-based articles (e.g., tires) prior to being subjected to stress related to the vulcanization process and normal use of this article during the manufacturing process.

Identification labels and their incorporation in rubber-based articles are described. The labels include RFID components and can be incorporated in tires. The labels can withstand the relatively harsh conditions associated with vulcanization.
