摘要： A tire includes a carcass, a belt structure, and a tread band. The belt structure includes at least two belt plies and at least one belt layer radially external to the belt plies. The at least one belt layer extends at least for an axial width of the at least two belt plies and includes at least one first elongated element and at least one second elongated element. The elongated elements form turns substantially oriented in a circumferential direction of the tire. The turns are alternately disposed along an axial development of the at least one belt layer. The at least one first elongated element is a hybrid cord including at least one high-elastic-modulus filament and at least one low-elastic-modulus filament that are twisted together. An elastic modulus of the at least one second elongated element is lower than an elastic modulus of the at least one first elongated element.

摘要： A tire having (i) an asymmetric tread profile with a shoulder drop difference of 0.3 to 0.9; and (ii) an asymmetric tread pattern so as to have a ratio between the inner void/solid ratio and the outer void/solid ratio of 1.1 to 1.50. By the above combination of features, handling and aquaplaning performance is remarkably improved even at high operating speeds without negatively affecting the wear resistance of the tread band.

摘要： 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.

摘要： A tire includes a carcass structure including at least one carcass ply, the carcass structure including a crown portion and two axially opposite side portions terminating in beads for mounting the tire on a rim; a tread band; and a belt structure interposed between the carcass structure and the tread band. The bead includes a bead core. The bead core includes: at least one first elongated element including at least one metal wire, and at least one second elongated element including at least one carbon fiber. The bead core results in an increased bead, forcing an improved bead unseating resistance and a decreased weight.
