The pneumatic tire comprises a crown, two sidewalls (1) and beads (2). Its carcass (3) is reinforced with layers laid in a circumferential direction between bead and a sidewall and anchored in (3). The bead anchoring zone (20) has a second reinforcing system (7) located circumferentially, co-operating with the adjacent reinforcement by a rubber anchoring mixture (9) between the reinforcing elements. The pneumatic tire comprises a crown, two sidewalls (1) and beads (2), has its carcass (3) reinforced with adjacent primary layers laid in a circumferential direction between at least one bead and a sidewall and anchored in the bead. The bead anchoring zone (20) contains a second reinforcing system (7) which is located circumferentially and co-operates with the adjacent portion of the carcass reinforcement by means of a rubber anchoring mixture (9) in contact with the two sets of reinforcing elements. The rubber mixture has a modulus of elasticity at 10 % deformation of 10-20 MPa. The rubber anchoring mixture contains at least one synthetic elastomer selected from styrene-butadiene rubber (SBR) or polybutadienes, with a total proportion of synthetic elastomer greater than 50 wt. % of the total elastomer. |
