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： A winter tyre has a tread pattern comprising two particularly wide longitudinal grooves (12, 13) so as to create in a footprint area working zones of the tread band - a central zone (LI) and two shoulder zones (L2, L3) - which are substantially independent of each other; the central zone (LI) occupies a substantial part of the tread band and comprises a plurality of circumferentially consecutive blocks provided with sipes (40) arranged in an oblique direction with respect to the equatorial plane of the tyre; the inclination of the sipes (40) formed in circumferentially adjacent blocks alternates in the circumferential direction, forming sequences of inclined and counter-inclined sipes.

摘要： The tread band (7) of a tyre (1) has two circumferential portions, a central one (13) and an inner intermediate one (14) respectively, that are subdivided into centre (20) and intermediate (24) blocks respectively; an inner-shoulder circumferential portion (16) has first (26) and second (27) inner-shoulder cuts, axially offset from each other and distributed in an alternated sequence, to confine a continuous inner-shoulder rest surface (29) with an undulated course; an outer intermediate circumferential portion (15) has first (34) and second (35) intermediate cuts, and an outer-shoulder circumferential portion (17) has first (30) and second (31) outer-shoulder cuts. The first and second intermediate cuts (34, 35) and the outer-shoulder cuts (30, 31) respectively, mutually converge at an angle of about 20° and are axially offset from each other and circumferentially distributed in an alternated sequence, to delimit continuous rest surfaces, an intermediate (36) and outer-shoulder (33) surface respectively, with an undulated course.

摘要： Tyre (1) for a motor vehicle having a tread (2) comprising a central portion (L1) straddling an equatorial plane (7) and two shoulder portions, the central portion (L1) being separated from the shoulder portions (L2, L3) of the tread by two first circumferential grooves (3, 6), at least two second circumferential grooves (4, 5) being present in said central portion (L1). The second circumferential grooves (4, 5) define a central circumferential rib (10) comprising a plurality of sipes (20), arranged parallel to each other and spaced apart from each other. The second circumferential grooves (4, 5) have a mid-line extending in an undulating pattern along the circumferential extension of the tyre. The mid-lines with undulating pattern are substantially in phase with each other along the circumferential extension of the tyre (1).
