    Abstract: Tire comprising at least two sidewalls, a crown provided radially externally with a tread, a carcass-type reinforcing structure and a crown reinforcement, the inner surface of the sidewalls and of the crown forming an inner wall of the tire, at least one portion of said wall being covered with a self-sealing layer comprising a thermoplastic stirene (TPS) elastomer and the tire being able to be inflated to a given service inflation pressure Pi. For any temperature within a given temperature range, between +30° C. and +100° C., the self-sealing layer has a loss factor tan δ of less than 0.2 and a dynamic modulus G* of less than Pi, tan δ and G* being measured at a frequency of 10 Hz.

    Abstract: A process for the manufacture of a tire the beads of which are without anchoring bead wires and are reinforced by complexes of layers of reinforcement elements of low angle, around which complexes the radial carcass reinforcement is anchored by winding, said process being characterized in that each complex is produced independently of the carcass reinforcement blank, the manufacture of said complex including using at least one raw blank of reinforcement elements which are oriented at a higher angle than the angle to be obtained in the vulcanized state, subjecting said ply to pre-extension before formation of a two-layer sleeve, the pitch, angle and width characteristics of which are obtained by pantograph effect upon a second extension.

    Abstract: Each bead of a pneumatic tire has the following characteristics:a) it has no bead wire and has an annular element whose tensile strength isppreciably less than that necessary for a bead wire;b) at least two reinforcing plies are placed in contact with or near this annular element;c) the combination of reinforcing plies has a tensile strength at least equal to that which would be necessary for a bead wire;d) the carcass ply is wrapped around the annular element;e) the outer region of the bead includes a rubber having an elastic loss modulus G" of less than 1 MPa and/or it includes a rubber whose thickness is at most equal to 2 mm.
