Beschreibung
Zusammenfassung:	A method for checking the electrical conductivity of tyres for vehicle wheels comprises: associating a tyre (2) with a plurality of angularly spaced pairs of electrodes, each pair of electrodes comprising a radially internal electrode (19) and a radially external electrode (18), wherein the radially external electrode (18) rests against a tread (9) of the tyre (2) and the radially internal electrode (19) rests against a bead (7) of the tyre (2). The radially external electrode (18) and the radially internal electrode (19) are substantially aligned with each other along a radial direction of the tyre (2). The method further provides for generating a voltage between the radially external electrode (18) and the radially internal electrode (19) and obtaining an electrical resistance value between the radially external electrode (18) and the radially internal electrode (19) of each pair of electrodes.
