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.
