A tire having a radial carcass reinforcement comprising a crown reinforcement formed of at least two working crown layers of inextensible reinforcement elements, which are crossed from one ply to the other, forming angles of between 10° and 45° with the circumferential direction, which itself is topped radially by a tread, said tread being joined to two beads by means of two sidewalls. The tire additionally comprises at least in each shoulder a layer of reinforcement elements which are parallel to each other in the layer and are oriented substantially perpendicular relative to the reinforcement elements of the working layer radially adjacent to said additional layer, said additional layer being radially adjacent to the edge of the radially outer working crown layer, and the axially outer end of said additional layer being located at a distance from the equatorial plane of the tire which is equal to the distance between said plane and the end of the working layer to which it is adjacent. |
