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： Car tyre (1) having a tread (2) comprising a central portion (L1) located across an equatorial plane (X-X), a first shoulder portion (L2) located towards an outer side of the tyre and a second shoulder portion (L3) located towards an inner side of the tyre, the central portion (L1) being separated from the first shoulder portion by two first circumferential grooves (3, 6), wherein:
- said first shoulder portion (L2) and said second shoulder portion (L3) comprise a plurality of first transverse grooves (56, 66) having a first end located substantially at the respective edge of the tread (2), having a width greater than or equal to about 4 mm and an axial extension equal to at least 50% of the width of the shoulder portion in which they are located;
- the number of said first transverse grooves (56, 66) of the first shoulder portion (L2) is lower than the number of said first transverse grooves of the second shoulder portion (L3);
- said central portion (L1) comprises at least one circumferential rib (9, 10, 11), comprising a plurality of second transverse grooves (16, 17, 18);
- said second transverse grooves (16, 17, 18) have a maximum width smaller than or equal to about 3 mm and define in said at least one circumferential rib (9, 10, 11) a void-to-rubber ratio smaller than or equal to about 0.06. [Fig. 2]

摘要： In a tyre for vehicle wheels a carcass ply (3a, 3b) is obtained by depositing on a radially outer surface (15) with respect to a forming drum (13) a plurality of strip- like elements (14) in circumferential side by side relationship with each other, superimposing a lateral longitudinal portion (18) of a strip-like element (14) on the lateral longitudinal portion (18) of an adjacent strip-like element (14). A central part (17) of each of the strip-like elements (14) comprises a plurality of parallel first cords (15a) having a first average diameter (d1). The two lateral longitudinal portions (18) each having a reduced thickness (S2), with respect to a thickness (S1) of the central part (17), and having at least one second end cord (15b) with a second average diameter (d2) smaller than the first average diameter (d1). The superimposition of the lateral longitudinal portions (18) provided with a reduced thickness (S2) and the smaller second cords (15b) allows providing the carcass ply (3a, 3b) with a substantially uniform thickness and maintaining, in the working conditions, the neutral axis (NA) of the radial section of the sidewall (12) of the tyre (1) inside the tyre (1) and outside the carcass structure (2).
