Abstract: Two crossed tire working layers (41, 42), comprise mutually parallel reinforcing elements forming, with the circumferential direction (XX′) of the tire, an angle at least equal to 20° and at most equal to 50°. The reinforcing elements are made up of individual metal threads or monofilaments having a cross section at least equal to 0.20 mm and at most equal to 0.5 mm. The tire also comprises major grooves of a depth D at least equal to 5 mm and of a width W at least equal to 1 mm, axially exterior major grooves (26) opening inwardly into a circumferential groove (24) comprising at least one bridge of rubber (27) connecting the two main faces of the groove, the at least one bridge of rubber having a length LB at least equal to W and a height h at least equal to half the depth D of the groove.

Abstract: Technique to increase the endurance of tires comprising two crossed working layers (41, 42), comprising mutually parallel reinforcing elements that form, with the circumferential direction (XX′) of the tire, an angle which is at least equal to 20° and at most equal to 50°. The reinforcing elements are made up of individual metal threads or monofilaments having a cross section which is at least equal to 0.20 mm and at most equal to 0.5 mm. The tire also comprises axially exterior sipes (24) having a mean width W at most equal to 1 mm, of a depth D at least equal to 5 mm and spaced apart, in the circumferential direction (XX′), by a circumferential spacing P at least equal to 4 mm, and axially exterior grooves (25) having a mean width W at least equal to 1 mm, of a depth D at most equal to 5 mm.

Abstract: 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°].

Abstract: 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).

Abstract: Technique to increase the endurance of tires comprising two crossed working layers (41, 42), comprising mutually parallel reinforcing elements forming, with the circumferential direction (XX′) of the tire, an angle which is at least equal to 20° and at most equal to 50°. The reinforcing elements are made up of individual metal threads or monofilaments having a cross section which is at least equal to 0.20 mm and at most equal to 0.5 mm. The tire also comprises grooves comprising a radially inferior zone Z1 having a radial height h1 equal to D/3, and a radially superior zone Z2 having a radial height h2 equal to 2D/3. These grooves have a mean width W at least equal to 1 mm and a depth D at least equal to 5 mm, and a maximum width W1 of zone 1, at least equal to 2 mm and a width of zone 2 at most equal to 1 mm.
