A tire (1) for a heavy vehicle of construction plant type and aims to improve the performance compromise between its lifetime in terms of wear, its resistance to attack and its grip. With the tread (2) having an axial width L0 and, on each side of an equatorial plane (XZ), at least one outer longitudinal cut (41) at an axial distance LE at least equal to 0.5*L0/2, and at least one inner longitudinal cut (42) at an axial distance LI at most equal to 0.4*L0/2, the at least one outer longitudinal cut (41) with an outer radial portion (411) that opens onto the tread surface (3) and has a mean width WE1 at least equal to 0.6 times its height HE1, and the at least one inner longitudinal cut (42) has an inner radial portion (422) that does not open onto the tread surface (3) and has a mean width WI2 at least equal to 0.6 times its height HI2.
