Tyre (10) comprising a radial carcass reinforcement (2) anchored in beads, the tyre (10) comprising two sidewalls (1), each sidewall (1) extending between a bead (4) and a crown (3), the two sidewalls comprising a first additional reinforcement (6) positioned either between the carcass reinforcement and the internal cavity of the tyre or axially on the outside of the carcass reinforcement, and at least one of the sidewalls comprising a second additional reinforcing reinforcement (5), this tyre being characterized in that the first additional reinforcement comprises a plurality of reinforcing elements of a textile nature directed at an angle of at least 80 degrees and at most 90 degrees with respect to the circumferential direction, and in that the second additional reinforcement (5) comprises, in the circumferential direction and alternating, a plurality of first parts (51); and of second parts (52), these second parts (52) having a mean width at least equal to 20 mm, these first and second parts having rupture strengths, that is to say rupture forces per unit width of reinforcement, which are such that the rupture strength of the second parts (52) is lower than the rupture strength of the first parts (51), and in that the first and second additional reinforcements are positioned on either side of the carcass reinforcement. |
