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.
