Abstract

A tire is disclosed that includes at least one annular bead wire forming a body of revolution about a reference axis. A carcass ply of generally toroidal shape about the same axis as the bead wire has a portion that is folded around the wire. A materials interface is defined at least in part by the junction between a rubber first mass and a second mass that includes an electronic member. By way of example, the electronic member is a passive radiofrequency identification transponder. The interface extends from a free edge of the folded portion of the carcass ply radially away from the reference axis to a circumferential junction line between the interface and the carcass ply.
