Abstract: An “all season” tyre (1) for cars and/or light transport vehicles is described, having a tread band (8) provided with a plurality of longitudinal channels and a plurality of grooves (6, 7, 11, 12, 13) and sipes (21, 22, 23, 24, 25) having a substantially transverse course, regularly arranged in the central ribs formed by the longitudinal channels and in the shoulder regions (L2, L3) over the whole tread band (8). The tread band (8) also has transverse notches resulting from joining a groove and a sipe having a transverse course, arranged consecutively to each other, and seamlessly extending substantially over the whole portion of the tyre containing them, i.e., the shoulder regions (L2, L3) or some of the central ribs (9, 10).

Abstract: A car tyre (1), in particular a high or ultra high performance car tyre also suitable for use on track, is described. The tread band (8) of the tyre has a central region (L1) having a limited extension, separated from two large shoulder regions, respectively an outer shoulder region (L2) and inner shoulder region (L3). At least the outer shoulder region (L2) and the central region (L1) have a set, limited in type, number, size and extension, of transverse grooves. In the tread band (8) there are also annular portions (S1, S2, M) substantially lacking grooves such that the void-to-rubber ratio being zero.

Abstract: All season tyre (1) for SUVs and Crossovers; the tyre having a tread band (7) provided with a plurality of sipes (21,22,23,24,25,26) regularly and homogeneously arranged, and a wide central region (LI) provided with three rows of blocks, at least wo of which are provided with transverse grooves only slightly inclined relative to a direction orthogonal to the equatorial plane. The central region (LI) lacks circumferential annular portions having a low void-to-rubber ratio located adjacent to central annular portions having a medium or high void-to-rubber ratio.

Abstract: A tire for vehicle wheels comprises a tread band (2), on which a first circumferential rib (14) is formed, on which a plurality of first notches (20) are formed, which extend as a whole over at least 80% of the width of the first circumferential rib and each of which comprises: ? i. a first portion (21) which is substantially rectilinear and has a first inclination with respect to a circumferential direction, ? ii. a second portion (22) which is substantially rectilinear and has a second inclination with respect to the circumferential direction having a sign opposite to said first inclination, and ? iii. a connecting portion (23) that extends between said first portion and said second portion; respective pluralities of the second and the third notches (30; 40), which are blind and substantially parallel to the first (21) and the second portion (22), respectively, of said first notches (20), are further formed on the first circumferential rib (14).

Abstract: Tyre (1) for vehicle wheels comprises a tread band (2) on which there are formed—a pair of shoulder regions (7, 8) that are axially opposite one another;—at least a first circumferential rib (12) interposed between said pair of shoulder regions and delimited by a first pair of circumferential grooves (10, 11);—a plurality of first blind recesses (20), which are formed in said first circumferential rib (12) and have a first longitudinal extension, and—a plurality of second blind recesses (30), which are formed in said first circumferential rib (12) and have a second longitudinal extension that is smaller than said first longitudinal extension,—at least a second circumferential rib (15) interposed between said pair of shoulder regions and delimited by a second pair of circumferential grooves (13, 14), and;—a plurality of through-recesses (40), which are formed in said second circumferential rib (15) and extend between the grooves of said second pair of circumferential grooves.

Abstract: A system for determining interaction between a tire and a contact surface during movement of a motor vehicle includes at least one first sensor and processing means. The at least one first sensor includes one or more first elongated piezoelectric elements which extend along at least a first portion of the tire. The at least one first sensor supplies a first signal to the processing means. The first signal is generated by rotation of the tire and is generated cyclically with each revolution of the tire. The processing means detects variations in time intervals between distinctive elements of the first signal. A tire including the system, a kit for detecting behaviour of a tire moving with respect to a contact surface, a method for monitoring events correlated with interactions between tires of a moving vehicle and a contact surface, and related systems, tires, methods, and vehicles are also disclosed.
