摘要
The invention relates to a tyre that comprises a crown reinforcement made of at least two crown working layers (71, 72) including reinforcement members. According to the invention, the tyre further includes, at least in each shoulder, two layers (2, 3) formed by circumferentially winding a complex strip (1) made of two layers (2, 3) consisting of continuous reinforcement members (4) extending from one layer to the other, said reinforcement members (4) being parallel in one layer and intersecting each other from one layer to the other at angles, relative to the circumferential direction, which are identical in terms of absolute value, wherein said additional complex strip is radially adjacent to the edge of a crown working layer (72), and the axially outer end of said additional complex strip is located at a distance (72) from the tyre equatorial plane that is at least equal to the distance between said plane and the end of the working layer to which it is adjacent. The complex strip (1) is previously obtained by crushing a tube containing the reinforcement members (4).
