    Abstract: A method of determining at least one characteristic of a tire selected from the three components of a resultant of forces which are exerted by the road on the contact area of a tire and the self-alignment torque generated by the tire, includes the steps of making at least two measurements of circumferential extension or contraction in at least one sidewall of the tire at two fixed points in space, which are situated at different azimuths along the circumference, and based on the measurements deriving a value for the selected characteristic.

    Abstract: A patch configured to fix an electronic system, which includes a sensor, to a tire. The patch has a foot with a surface configured to be fixed to the tire. The foot has at least two portions connected to one another by at least one bridging element. The bridging element has, in a section which is parallel to the surface of the foot that is configured to be fixed to the tire, a surface area which is smaller than the overall surface area in the same section between the connected portions of the foot. In the same section, the bridging element continuously connects the connected portions of the foot.

    Abstract: Disclosed is a methodology for deriving data related to various selected tire (10) conditions. One or more sensors are analyzed in a manner similar to that of analyzing an electro-cardiogram taken from a human patient in order to determine selected operational characteristics of the monitored tires (10). Analysis of the signal waveforms may involve analysis of a single waveform and/or comparison of paired waveforms originating for sensors associated with a single tire or paired tires (10).
