Pneumatic tire

Sidewall of a pneumatic tire

A tire, designed to carry heavy loads, having a radial carcass reinforcement formed of at least one ply of inelastic reinforcing elements and anchored in each bead to a bead wire so as to form a turn-up whose end is a radial distance H away from the base of the bead, each bead being reinforced by at least two additional reinforcement armatures, at least one first armature being formed of radial reinforcement elements and at least one second armature being formed of elements that make with the circumferential direction an angle &agr; such that 0&deg;&lE;&agr;&lE;45&deg;, the first reinforcement armature being formed of radial elements and being wrapped around the bead wire outside the carcass reinforcement while the second armature is not wrapped around the said bead wire.

Reinforcing tire bead for a radial tire

A tire for heavy loads and having beads intended to be mounted on flat rim seats or rim seats which are inclined at 5&deg;, including at least one radial carcass ply formed of inextensible reinforcement elements and anchored in each bead to a bead wire to form an upturn, the end of which is located at a radial distance H from the base of the bead. Each bead is reinforced by at least two additional reinforcement armatures, at least one first armature formed of at least one ply of radial textile reinforcement elements which is located axially to the outside of a second armature formed of at least one ply of inextensible elements forming an angle &agr; with the circumferential direction such that 0&deg;&lE;&agr;&lE;45&deg;.
