Abstract
The invention relates to a tire (100) comprising a crown (110), of which a most radially inner working layer (114) is corrugated, sidewalls (120A, 120B), bead ribs (130A, 130B), a toroidal inflation cavity (150), and a stiffening structure (160) including at least one stiffening element (160A), which extends continuously in the toroidal cavity from a sidewall and / or bead to the crown, which includes a penetration point (163A), in which the stiffening element penetrates the crown to anchor itself therein, and an anchoring section (166A), entirely arranged in the crown and extending axially so as to be entirely disposed radially above an anchoring corrugation (114.2) among the corrugations of the corrugated working layer.The anchor section is radially convex outwards, forming a summit portion which is arranged radially outside the rest of the anchor section, and axially on either side of which the anchor section extends axially in a curved manner.
