Abstract: A tyre 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 tyre. 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 tyre, 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 tyre during the tyre's manufacture.

Abstract: A heat-expandable rubber layer is provided to an inner all of a pneumatic tire when the tire is in an uncured state. The rubber layer is expanded when the tire is in a vulcanized state. Once expanded, the rubber layer is capable of reducing rolling noises of the tire. The rubber layer includes an elastomer composition based on at least an elastomer, e.g., natural rubber or butyl rubber; a reinforcing filler, e.g., silica and/or carbon black; between 10 and 80 phr of a blowing agent, e.g., an azodicarbonamide compound; and between 10 and 50 phr of a hot-melt compound with a melting point between 70° C. and 150° C., e.g., urea. The combination of the blowing agent and the hot-melt compound, at recommended high contents, makes it possible to very greatly reduce an expansion ratio and therefore a thickness of the rubber layer once the pneumatic tire is vulcanized, without affecting noise absorption properties provided by the blowing agent.
