Provided is a pneumatic tire including one fastener in a separable pair of mechanical fasteners, the one fastener being disposed on the tire inner surface. The one fastener includes at least two components. The at least two components are fixed together while sandwiching the fixing member made from a resin or a resin composition composed of a blend of a resin and an elastomer.

An apparatus and method for monitoring parameters of a tire using a piezoelectric device is provided. The piezoelectric device is mounted as part of a tire mountable apparatus with a circumferential orientation in a tire such that that the direction defined by length of the piezoelectric device is generally aligned with the direction of rotation of the tire. This can lead to increased coupling of the piezoelectric device to changing circumferential tire shape as the piezoelectric device enters and exits the contact patch of the tire while at the same time reducing the coupling of the piezoelectric device to changing lateral tire shape. Contact patch entry and exit times from piezoelectric signals generated by the piezoelectric device can be more readily identified, leading to increased accuracy of tire parameters determined from the contact patch entry and exit times, such as tire revolution count, tire speed, and contact patch angle.

The invention further relates to a method for producing a tire pressure monitoring unit.

A pneumatic tire (1) includes a mechanical fastener (3) formed of at least two or more fastener components (3a, 3b) and attached to a tire inner surface (2). In such a pneumatic tire (1), the two or more fastener components (3a, 3b) of the mechanical fastener (3) are fixed with a resin reinforcement member (7) sandwiched therebetween, the resin reinforcement member (7) including at least one layer of a resin film or resin sheet including any of: (a) a resin or a resin composition made of a blend of resin and an elastomer; (b) a resin or a resin composition made of a blend of a resin and an elastomer including arranged fibers; and (c) a resin or a resin composition made of a blend of a resin and an elastomer with short fibers compounded therein.

A flexible sensor for monitoring operating parameters, including pressure and temperature, of a flexible structure, such as a tire, provides electrodes and an active area that are formed of flexible materials. In particular, the active area may be formed from an elastomeric piezoresistive material, such as an ionic liquid-polymer. The flexible properties of the sensor allow it to be readily incorporated into the body of a tire during manufacture. This allows the operating parameters of the tire to be monitored, such as in real-time, while the tire is in operation. Furthermore, the sensor is formed of materials that allow the sensor to be formed using additive manufacturing techniques, such as 3D (three-dimensional) printing. As such, the sensor may be 3D printed together with another structure, such as a tire tread, so that the sensor is integrated therein.

An apparatus (14) for installation and removal of electronic components (10) for a tire comprises an expansion device (16) having a plurality of movably supported longitudinal prongs (18), wherein the expansion device (16) is adapted for moving at least a part of the plurality of prongs (18) between a neutral position with a least distance between the prongs (18) and at least one expansion position with a distance between the prongs (18) exceeding the least distance. The prongs (18) comprise prong tips (20), which each comprise a curved engagement surface (22), wherein each prong is adapted for engaging an exposed top lip (8) of an elastic container (2), in which the electronic component (10) is storable. The expansion device (16) is adapted for moving at least a part of the plurality of prongs (18) to an expansion position with the engagement surfaces (22) engaging the top lip (8) of the container (2), in which expansion position the top lip (8) is expanded.

The RF tag known in the art incorporated in a tire has a problem that it can easily get distorted when the stresses occurring in the running tire converge on its vicinity. The present invention provides a tire (1) configured to prevent distortion from occurring in the RF tag (50) incorporated therein. The tire (1) includes an RF tag structure (50A) which is constructed of the RF tag (50) covered with a coating rubber (51). The modulus of elasticity of the coating rubber (51) is higher than that of the rubbers of the adjacent members (13, 32) located adjacently on the respective axial sides of the coating rubber (51).

A method is provided for storing tire information in a tire sensor. For this purpose, a tire sensor is fastened to a tire having a passive RFID transponder. The RFID transponder is then supplied with energy via an energy field, with the result that the RFID transponder emits the stored tire information. If the tire sensor has determined that the tire sensor is fastened to the tire, the tire information is received and is permanently stored in the tire sensor. The tire information written to a tire sensor is preferably transmitted to the vehicle by the tire sensor and is then taken into account during a movement-dynamic function, for example.
