Abstract

A tire for heavy loads, having an inextensible radial carcass ply anchored to a bead wire to form an upturn, the end of which is located at a radial distance from the base of the bead. Each bead is reinforced by at least two additional reinforcement armatures, one armature formed of radial inextensible metallic reinforcement elements and a second armature formed of metallic elements forming an angle with the circumferential direction, the first armature being formed of at least one ply wound around the anchoring bead wire on the inside of the carcass reinforcement to form two strands, such that the axially inner strand, between the radially lower end of its radially upper edge parallel to the meridian profile of the carcass reinforcement and its point of tangency with the anchoring bead wire, follows a rectilinear trace referred to as 'shortest-path'.
