Technique to increase the endurance of tires comprising two working layers (41, 42), comprising mutually parallel reinforcing elements (411, 421) each forming, with the circumferential direction (XX′) of the tire, an oriented angle (AA, AB), such that these respective angles are of opposite sign, the reinforcing elements being comprised of individual metal threads, by combining a manufacturer-recommended direction of rotation (SR) and an optimized design of tread pattern. The tire also comprises axially exterior major grooves (24) in the tread (2) having a mean linear profile L of a width W at least equal to 1 mm and of a depth D at least equal to 5 mm. Different conditions governing the angular orientations of the mean linear profiles L of the axially exterior major grooves (24) apply to the left-hand axially exterior portion (22) and to the right-hand axially exterior portion (23) of the tread (2).
