TYRE FOR HEAVY VEHICLES COMPRISING, AT LEAST IN EACH SHOULDER, AT LEAST TWO ADDITIONAL LAYERS IN THE CROWN REINFORCEMENT

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