<p>A tire comprising two beads (20), two sidewalls (30) joining in a crown, and at least one carcass reinforcement (60) extending from the beads through the sidewalls to the crown, the carcass reinforcement being anchored in the two beads by a turn-up around an annular reinforcing structure (70) in such a way as to form in each bead an incoming portion (61) and a wrapped-around portion (62), wherein each bead comprises a bead filler (110) and an outer band (120), the latter being placed axially outside of both the carcass reinforcement and the bead filler, wherein the outer band (120) is made of a rubber compound having an elastic modulus G′ less than or equal to 15 MPa and a viscous modulus G″ such that: G″ [MPa]≦̸0.2G′ [MPa]−0.2 MPa, the elastic and viscous moduli being measured at 23° C.</p> |
