Abstract: A pneumatic tyre (10) having a reinforced bead structure (15), wherein at least one flipper (17) is provided to at least parcially envolope the respective annular reinforing element (14) and bead fillter (16). The flipper comprises a plurality of mutually substantially parallel elongated reinforcing elements which comprises at least one preformed threadlike metallic element having a diameter in the range of from 0.25 mm. The resulting tyre has improved durability,especially at high speed and/or extreme driving conditions, combined with exellemt handling and ride comfort characteristics.
Abstract translation: 一种具有增强的胎圈结构（15）的充气轮胎（10），其中至少一个胎圈（17）被设置成至少与相应的环形加强元件（14）和胎圈填充器（16）基本相同。 导板包括多个相互基本上平行的细长加强元件，其包括直径在0.25mm范围内的至少一个预成型的线状金属元件。 所得到的轮胎具有改善的耐久性，特别是在高速和/或极限驾驶条件下，结合起重机操纵和乘坐舒适特性。

Abstract: A pneumatic tyre includes a pair of axially-spaced-apart annular reinforcing elements and bead fillers, a carcass structure, at least one flipper, a tread band, a belt structure, and at least one pair of sidewalls. The carcass structure includes at least one carcass ply, extends between the annular reinforcing elements, and is secured at axially opposite end portions to respective annular reinforcing elements. Each end portion is turned up around the respective annular reinforcing element. Each bead filler is disposed radially outward of the respective annular reinforcing element. The at least one flipper at least partially envelops an associated annular reinforcing element and bead filler and includes a plurality of first elongated reinforcing elements that are substantially parallel to each other. The first elongated reinforcing elements include at least one preformed metallic element having a diameter greater than or equal to 0.05 mm and less than or equal to 0.25 mm.

Abstract: Tyre for motor vehicles, provided with a belt structure (3) interposed circumferentially between the carcass (2) and the tread band (4), and comprising at least one pair of belt plies (5,7) radially superimposed on each other and extending axially substantially by the same amount as said tread band. Each ply (5,7) has a plurality of cords (6,8) orientated obliquely with respect to the equatorial plane of the tyre and in opposite directions, and a reinforcing layer (10) radially external to said at least one pair of belt plies (5,7), having reinforcing elements (11) which are substantially parallel to each other and parallel to the equatorial plane. The reinforcing elements (11) of the 0° layer comprise single metal wires preformed according to a given preforming ratio, which have a high elastic modulus and a considerable elongation at low stresses.

Abstract: A pneumatic tire having a belt structure includes: a first belt layer; a second belt layer in a radially inner position with respect to the first belt layer, a third belt layer in a radially inner position with respect to the first and second belt layers, each belt layer including a plurality of elongated reinforcing elements disposed at a first, second and third belt angle respectively. The first and second belt angles have an absolute value of 15 to 40 degrees; the second angle is of opposite sign with respect to the first belt angle; and the third belt angle has an absolute value of 40 to 90 degrees and is of opposite sign with respect to the second belt angle. The belt structure also includes a zero degree belt layer placed in a radially outer position with repeat to the first belt layer including elongated reinforcing elements arranged such as to form a belt angle which is substantially zero.
