摘要： A tire comprising a crown, two sidewalls and two beads, a carcass reinforcement anchored in each of the beads and a crown reinforcement. The carcass reinforcement comprises at least two circumferential alignments of first reinforcing threads of high elasticity modulus, each circumferential alignment of first reinforcing threads being, within each bead, bordered axially inwardly and axially outwardly by second reinforcing threads oriented substantially circumferentially of a modulus greater than or equal to that of the first reinforcing threads. The first reinforcing threads and the second reinforcing threads are separated by a layer of mix of very high elasticity modulus. The outer surface of each bead comprises a seat, a frustoconical wall of substantially radial orientation radially inwardly adjacent to a wall section in the shape of an arc of a circle EF of center C which center C is arranged axially outwardly relative to the bead. Considering a straight line CD passing through the center C and the bead and forming an angle nullnullnull45null5 degrees relative to the axis A of the tire, all the second reinforcing threads are arranged at a radial distance from the axis A less than or equal to the locus of the line CD.

摘要： Formation of a carcass ply takes place by laying down onto a toroidal support (11), a first and a second series of strip-like sections (13, 14) cut to size from a continuous strip-like element (2a) and each comprising longitudinal thread-like elements (15) incorporated into a layer of elastomer material (18). The sections (13) of the first series are sequentially disposed at some circumferential distance from each other, to form side portions (19) to the end flaps (19a) of which primary portions (4a) of respective bead-reinforcing structures (4) are applied. The sections (14) of the second series are each interposed in the space defined between two sections of the first series (13), with the respective end flaps (20a) overlapping the primary portions (4a) of the annular structures (4). Additional portions (24) of the annular structures are applied to the end flaps (20a) of the sections (14) belonging to the second series.

摘要： A pneumatic radial tire includes a bead portion having a plurality of bead cores, and one or plural radial carcass plies wound up from a tire inner side toward an outer side at the respective bead cores. One-half or more of the number of end portion(s) of the radial carcass ply (plies) wound up on the bead cores is/are positioned at each bead core within a range of 35 to 55% of a tire section height as measured from the reference line of the tire section height. In accordance with this structure, rigidity from the bead portion to a side portion of the tire markedly improves. Accordingly, even when the tire is large and a load applied thereto is increased, deformation of the bead portion in the loaded state is suppressed, a strain level of the bead portion is reduced, and excellent durability of the bead portion is ensured.
摘要翻译：充气子午线轮胎包括具有多个胎圈芯的胎圈部，以及在胎圈芯处从轮胎内侧向外侧卷绕的一个或多个胎体帘布层。在胎圈芯上卷绕的径向胎体帘布层（帘布层）的端部的数量的一半以上被定位在每个胎圈芯的轮胎截面高度的35至55％的范围内从轮胎截面高度的参考线测量。根据该结构，从胎圈部向轮胎侧部的刚性明显提高。因此，即使在轮胎大且施加负荷的情况下，也能够抑制加载状态下的胎圈部的变形，从而能够减小胎圈部的应变水平，确保胎圈部的耐久性。
