Tyre, having a tread band comprising: - a central annular portion, located across the equatorial plane (X-X), and two shoulder annular portions (A2, A3), separated from said central annular portion by two circumferential grooves (3, 4); said central annular portion having at least one circumferential row of central blocks, comprising a plurality of central blocks, and at least two rows (9, 10) of lateral blocks, opposed to each other relative to said at least one circumferential row of central blocks, and comprising a plurality of lateral blocks, wherein - the central blocks are circumferentially separated by first transverse grooves and - said central blocks have a first and a second portion (20a; 20b) located opposite to each other relative to the equatorial plane (X-X); - said central blocks and said lateral blocks have a circumferential dimension greater than 2% of the development extension of the tread of the tyre; - said lateral blocks have an elongate portion and a head portion located at an end of said elongate portion; said elongate portion having a dimension S1 in axial direction and said head portion having a dimension S2 in axial direction, where S2>S1; - the elongate portion extends according to an extension direction forming an angle α relative to the equatorial plane comprised between 0° and 30°; - said elongate portion has an axially outer lateral wall facing one of said circumferential grooves (3, 4) and an axially inner lateral wall facing one of said first and second portions (20a, 20b) of the central blocks; - said head portion has a first transverse wall located so as to form with said axially inner lateral wall a concavity which points towards the equatorial plane (X-X) and is such that the first or the second portion (20a; 20b) of the central block being subsequent in axial direction faces said concavity and is at least partially surrounded by said axially inner lateral wall and by said first transverse wall; - said first and second portions (20a; 20b) of a same central block are circumferentially staggered; - said first and second portions (20a; 20b) have a second transverse wall facing the first transverse groove and at least partially opposed to said first transverse wall. - a central annular portion, located across the equatorial plane (X-X), and two shoulder annular portions (A2, A3), separated from said central annular portion by two circumferential grooves (3, 4); said central annular portion having at least one circumferential row of central blocks, comprising a plurality of central blocks, and at least two rows (9, 10) of lateral blocks, opposed to each other relative to said at least one circumferential row of central blocks, and comprising a plurality of lateral blocks, wherein - the central blocks are circumferentially separated by first transverse grooves and - said central blocks have a first and a second portion (20a; 20b) located opposite to each other relative to the equatorial plane (X-X); - said central blocks and said lateral blocks have a circumferential dimension greater than 2% of the development extension of the tread of the tyre; - said lateral blocks have an elongate portion and a head portion located at an end of said elongate portion; said elongate portion having a dimension S1 in axial direction and said head portion having a dimension S2 in axial direction, where S2>S1; - the elongate portion extends according to an extension direction forming an angle α relative to the equatorial plane comprised between 0° and 30°; - said elongate portion has an axially outer lateral wall facing one of said circumferential grooves (3, 4) and an axially inner lateral wall facing one of said first and second portions (20a, 20b) of the central blocks; - said head portion has a first transverse wall located so as to form with said axially inner lateral wall a concavity which points towards the equatorial plane (X-X) and is such that the first or the second portion (20a; 20b) of the central block being subsequent in axial direction faces said concavity and is at least partially surrounded by said axially inner lateral wall and by said first transverse wall; - said first and second portions (20a; 20b) of a same central block are circumferentially staggered; - said first and second portions (20a; 20b) have a second transverse wall facing the first transverse groove and at least partially opposed to said first transverse wall.
