An assembly of a pneumatic tire and of a wheel, the pneumatic tire () being fitted to the wheel. The assembly comprises first and second self-sealing products housed in the internal volume (V) of the pneumatic tire (). The first self-sealing product, referred to as solid self-sealing product (OS), covers a predetermined part of the internal surface of the pneumatic tire (). The relative position of this predetermined part in the pneumatic tire () does not substantially vary under the effect of gravity. The second self-sealing product, referred to as liquid self-sealing product (OL), is in the liquid form.

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.
