Technique to increase the endurance of tires comprising two crossed working layers (), comprising mutually parallel reinforcing elements () forming, with the circumferential direction (XX') of the tire, an angle at least equal to 20&#xb0; and at most equal to 50&#xb0;, the reinforcing elements being made up of individual metal threads or monofilaments having a cross section at least equal to 0.20 mm and at most equal to 0.6 mm. The end of the monofilaments comprises flats such that they reduce the shear forces in the rubber compounds of the tire under compressive loading.
