Patent ID: 8291951

Claim:
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 a circumferential direction of the tire, and topped radially by a tread, said tread being joined to two beads by means of two sidewalls, an axially widest working crown layer being radially internal to the other working crown layers; and in each shoulder, a single additional layer of reinforcement elements which are parallel to each other in said additional layer and are oriented substantially perpendicular relative to the reinforcement elements of one of the working layers radially adjacent to said additional layer; wherein an axially inner end of said additional layer is radially adjacent to an edge of a radially outer working crown layer; wherein at least part of said additional layer is coupled to an edge of the axially widest working crown layer, wherein the crown reinforcement is finished off radially to the outside by at least one supplementary ply, referred to as a protective ply, of what are called elastic reinforcement elements, which are oriented relative to the circumferential direction at an angle of between 10° and 45° and of the same direction as the angle formed by the inextensible elements of the working ply which is radially adjacent thereto, and wherein the crown reinforcement comprises at least one continuous layer of circumferential reinforcement elements.
