Abstract: A tire is described that includes a casing defining a cavity and equipped to receive an object, such as an electronic circuit, for example, through use of a two-part attachment, such as a touch-close attachment, of which a first part is fixed to a wall of the casing and a second part can be joined to the first part when placed in contact with the first part to keep the object on the casing in a service position. The first part of the attachment includes connection elements that are an integral part of the wall of the casing of the tire. The connection elements allow these two parts to have freedom to move relative to each other, thereby limiting the transmission of stresses, which affect the wall of the tire, to the object. The connection elements may be loops of flexible thread formed by the extremities of turns of a coiled thread integrated into the wall of the tire during the tire's manufacture.
