PROBLEM TO BE SOLVED: To provide a tire bead facilitating mounting that has overcoming problems of prior art. SOLUTION: A tire comprises two beads (2) set to be in contact with seats of a mounting rim and two sidewalls (1), the tire comprising first reinforcing threads (4) forming a carcass reinforcement (3). Each bead comprises an anchoring structure (20) for the carcass reinforcement formed of at least one circumferentially oriented second reinforcing thread (7) cooperating with an adjacent portion of the carcass reinforcement by means of an anchoring rubber material (9) having an elasticity modulus at 10% deformation at least equal to 30 MPa. This tire is characterized in that, at least axially on one side of the anchoring structure (2) of the carcass reinforcement (3), a rubber mix referred to as "decoupling mixtures" (11, 12), this decoupling mixture having an elasticity modulus, at 10% deformation, less than half of the elasticity modulus of the anchoring mix.
