A tire tread (1), for a heavy-duty construction plant vehicle, having an improved compromise between resistance to mechanical attack caused by stony ground and grip on muddy ground. The tread (1) having five rows (41, 42, 43) separated in pairs by a longitudinal cut (51, 52) and distributed, along the transverse direction (YY′), in a median row (43), two intermediate rows (42), and two lateral rows (41), the blocks (31, 32, 33) in one and the same row (41, 42, 43) being separated in pairs by a transverse cut (61, 62, 63), each transverse cut in a lateral row (41) is a transverse groove, each transverse cut (62) in an intermediate row (42) with a first transverse groove portion (621) and a second transverse sipe portion (622), and each transverse cut (63) in the median row (43) is a transverse sipe which is offset along the longitudinal direction (XX′).
