摘要

The present invention relates to a tire comprising a crown reinforcement formed of at least two working crown layers of reinforcement elements. According to the invention, the tire also comprises at least in each shoulder two layers formed by circumferential winding of a complex formed of two layers consisting of continuous reinforcement elements passing from one layer to the other, said reinforcement elements are parallel in a layer and crossed from one layer to the other with angles with respect to the circumferential direction are identical in absolute value, said additional complex strip being radially adjacent to the edge of a working crown layer, and the axially outer end of said strip additional complex being situated at a distance from the equatorial plane of the tire at least equal to the distance separating said plane and the end of the layer to which it is adjacent.
