    Abstract: The bead portion of the pneumatic tire includes a bead structure having a bead core composed of a bead cord, and an annular plate which extends to the tire circumferential direction and is formed of a resin material. The annular plate has a planar first annular ring portion extending to the tire circumferential direction and a second annular ring portion positioned outside the tire radial direction of the first annular portion and extending to the tire circumferential direction, the first annular portion is provided along the bead structure, and the second annular portion is further inclined to the outside in tire width direction of the first annular portion.

    Abstract: The invention relates to a tire having at least one carcass reinforcement (2) comprising reinforcers, surmounted radially on the outside by a crown reinforcement (3) comprising two axial ends S, itself radially on the inside of a tread (4), said crown reinforcement (3) being made up of at least one layer of reinforcement elements, said tread (4) being connected to two beads (5) by way of two sidewalls (6), said beads (5) being intended to come into contact with a rim flange having a rim flange top C, each bead having at least one circumferential reinforcement element (7) known as a bead wire, said carcass reinforcement (2) comprising an end (8) at each bead (5), the end (8) of the carcass reinforcement (2) being turned up once in an outward radial direction of the tire and about said bead wire, so as to form a turnup, then being folded in the radially outward direction so as to form a fold of the carcass ply (2), said fold forming a radially external end (12a) and three adjacent parts along an axial axis made up of a central part (10), of an axially internal lateral part (11), and of an axially external lateral part (0), the fold being executed in an outward axial direction with respect to the centre of the tire, characterized in that a decoupling elastomer composition (14) having a secant modulus at 10% extension of greater than or equal to 10 MPa and preferably greater than or equal to 30 MPa and less than or equal to 60 MPa is present between the axially internal lateral part and the central part of said turnup, and at the radially external end (12a) of said turnup (12), said elastomer composition being present along a radial length comprised between the radially external end of the turnup and a radially internal point F with respect to the end of said turnup, said point being situated on the sidewall and at a distance from said radially external end by a length greater than 10 mm, and in that the radially external end (12a) of the turnup (12) is disposed between the rim flange top C and a point D, said points C and D being situated at the surface of the sidewall (6) and disposed on either side of a point E situated on the sidewall corresponding to the nominal section width, said point D being disposed at a maximum radial length equal to 85% of the length present between the axial end S of the crown reinforcement (3) and the rim flange top C.

    Abstract: In a carcass (13), between first sections (13A) in which an inter-cord distance between a body portion and turn-back portions gradually decreases outward in a tire radial direction and second sections (13B) in which the inter-cord distance gradually increases, there are disposed first distance-invariant sections (13C) in which the turn-back portions (14B) are brought closer to the body portion (14A) that becomes a substantial bending neutral axis and in which the inter-cord distance is constant, so compressive force acting on the cords of the turn-back portions (14B) can be reduced. By disposing the first distance-invariant sections (13C) between the first sections (13A) and the second sections (13B), the direction of the cords of the turn-back portions (14B) is not suddenly changed, so it becomes difficult for stress to concentrate in the rubber between the cords of the turn-back portions (14B).

    Abstract translation: 在胎体（13）中，在轮胎径向方向上主体部分和折回部分之间的线间距离逐渐减小的第一部分（13A）之间，并且其中帘线间距离 逐渐增加，设置第一距离不变部分（13C），其中折回部分（14B）更靠近成为实质弯曲中立轴线的主体部分（14A），并且其中绳间距离为 可以减小作用在折回部分（14B）的帘线上的压缩力。 通过在第一部分（13A）和第二部分（13B）之间布置第一距离不变部分（13C），折返部分（14B）的帘线的方向不会突然改变，因此难以 应力集中在回转部分（14B）的帘线之间的橡胶中。
