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.
