Abstract

Pneumatique (1) comprenant un sommet (2) comportant une armature de ceinture ayant une largeur axiale W, une bande de roulement (5) en matériau élastomérique, la bande de roulement comprenant une pluralité de blocs de sculpture (50), deux blocs de sculpture axialement adjacents étant séparés par une rainure (7) s'étendant au moins en partie circonférentiellement, une couche de rigidification constituée d'éléments filaires de renfort rigides en compression, lesdits éléments filaires de renfort étant orientés selon une direction moyenne formant un angle compris entre 50° et 90° avec la direction circonférentielle C, dans lequel les éléments filaires de renfort sont fractionnés en se déplaçant le long de leur direction moyenne, formant des fragments avec recouvrement d'amplitude « R » entre fragments adjacents circonférentiellement et dans lequel les éléments filaires de renfort ont une dimension minimale de 0,15 mm dans le plus petit axe de leur section.Tire (1) comprising a crown (2) comprising a belt reinforcement having an axial width W, a tread (5) made of elastomeric material, the tread comprising a plurality of tread blocks (50), two blocks axially adjacent sculpture being separated by a groove (7) extending at least partially circumferentially, a stiffening layer made up of rigid reinforcing wire elements in compression, said reinforcing wire elements being oriented in a medium direction forming an angle included between 50 ° and 90 ° with the circumferential direction C, in which the reinforcing wire elements are divided by moving along their mean direction, forming fragments with overlap of amplitude "R" between circumferentially adjacent fragments and in which the reinforcing wire elements have a minimum dimension of 0.15 mm in the smallest axis of their section.
