The device is composed of a series of two or more substantially circular protuberances that are eccentric with respect to the rim axis, and formed on the mounting rim in an axially inner position with respect to the bead seat, creating a confining space adjacent the bead seat and radially outwardly projecting with respect to it, so as to constitute a limit to the axial shifting of the tire bead heel towards the central well of the rim. |
