Abstract: A pair of motor vehicle tyres includes a front tyre and a rear tyre to be mounted respectively on a front wheel and a rear wheel of a two-wheeled vehicle, each tyre of the pair having a tread band extending around an axis of rotation. The tread band of the front tyre includes a central annular portion straddling an equatorial plane and two annular shoulder portions disposed on axially opposite sides of the central annular portion. The central annular portion includes at least a pair of first grooves extending substantially longitudinally on opposite sides of the equatorial plane in such a way as to form a concavity directed toward the equatorial plane. Each shoulder portion includes a plurality of second grooves isolated from the first grooves and extending substantially transversally so as to form an average inclination with the equatorial plane greater than 90°.

Abstract: Motor vehicle tyre adapted to be mounted on the rear wheel of a motor vehicle, includes a tread band having a tread pattern including a module which is repeated along a direction of circumferential extension of the tyre. The module has at least one first pair of first grooves inclined in opposite directions with respect to an equatorial plane of the tyre, and extending from the equatorial plane toward a respective shoulder; at least one second pair of second grooves inclined in opposite directions with respect to the equatorial plane and extending from the equatorial plane toward a respective shoulder. The first and the second grooves are staggered relative to each other in the circumferential direction in such a way as to maintain a substantially constant distance of less than half the pitch, at the equatorial plane between each first or second groove and the adjacent one in the circumferential direction.

Abstract: A tyre (1) for motor vehicles, having a tread band (8) extending around a rotation axis (Z) and comprising an annular central portion (A) astride of an equatorial plane (X-X) of the tyre, two annular shoulder portions (B) arranged on axially opposite sides with respect to the annular central portion (A) and two annular side portions (C) each arranged between the annular central portion (A) and a respective annular shoulder portion (B), the tread band (8) having at least one module (Ti; T2) replicated along a circumferential direction of the tyre and comprising: at least one plurality of primary grooves inclined with respect to the equatorial plane (X-X) and arranged at least on the annular portions (B), (C); at least one plurality of secondary recesses arranged mainly on the annular central portion (A) and on at least one annular side portion (C); wherein a substantial disappearance of the secondary recesses determines a difference in the empty/solid ratio on the annular central (A) and side (C) portions betw

Abstract: A tyre for motorcycles, has a tread band and includes an annular central portion and two annular shoulder portions. The tread band includes at least one first groove extending from one annular shoulder portion to the other annular shoulder portion and having a first vertex at the annular central portion, and at least one pair of second grooves arranged on opposite sides with respect to the equatorial plane, each groove of said at least one pair of second grooves being inclined with respect to the equatorial plane and extending from a respective annular shoulder portion up the annular central portion without intersecting the equatorial plane. The distance in the circumferential direction between an axially inner end of each groove of said at least one pair of second grooves and the first vertex is no greater than 3.5% of the circumferential extension of the tread band.

Abstract: A tyre for motor vehicles, in particular for rear wheels of motor vehicles, has a tread band including an annular central portion, two first annular side portions and two second annular side portions, each arranged between the annular central portion and a respective first annular side portion and being narrower than the first annular side portion.

Abstract: Motorcycle tyre suitable for mounting on the rear wheel of a motorcycle, including a tread band having a tread pattern includes a module which is repeated in a direction of circumferential extension of the tyre, the module having: at least two substantially longitudinal first grooves which are inclined opposite to each other with respect to the equatorial plane of the tyre; and at least two substantially longitudinal second grooves which are inclined opposite to each other with respect to the equatorial plane. Each substantially longitudinal first groove alternates with a second longitudinal groove. The substantially longitudinal first grooves have, in a direction axially away from the equatorial plane of the tyre, two substantially consecutive curvilinear sections, the first section of which has a convexity and the second section of which has a concavity directed in the rolling direction of the tyre.
