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.
