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 (A1, A2) the absolute value of which is at least equal to 20° and at most equal to 50°, such that these respective angles are of opposite sign. The reinforcing elements of each ply are made up of individual metal threads or monofilaments having a cross section the smallest dimension of which is at least equal to 0.20 mm and at most equal to 0.5 mm. The tire also comprises axially exterior major grooves (24) in the tread (2). The mean linear profile L of the axially exterior major grooves (24) of a width W at least equal to 1 mm and of a depth D at least equal to 5 mm forms, with the circumferential direction (XX′), an angle C belonging to the interval [min(A1,A2)+100°, max(A1, A2)+80°].
