Abstract

L'invention concerne un pneumatique comportant une bande de roulement (1). La bande de roulement (1) comprend une pluralité de blocs (3) séparés par des rainures (5), chaque bloc (3) comportant une surface de contact (7) destinée à venir en contact avec un sol et au moins une incision complexe (9) de profondeur P et de longueur L, chaque incision complexe étant délimitée par deux parois de gomme en vis-à-vis. Pour au moins une incision complexe (9) de longueur L, chaque paroi délimitant cette incision complexe comprend une alternance de bosses (11) et de creux (13) dans la longueur L de cette incision complexe (9). L'alternance de bosses (11) et de creux (13) s'étend de la surface de contact (7) du bloc (3) jusqu'à une profondeur Pa inférieure à la profondeur P de l'incision complexe. Les alternances de bosses (11) et de creux (13) des deux parois délimitant l'incision complexe sont complémentaires de sorte que l'espace entre ces parois est globalement constant dans cette zone d'alternance. Au moins une paroi délimitant l'incision complexe comprend, à partir de la profondeur Pa, un enfoncement (15), ledit enfoncement s'étendant dans la longueur L de l'incision complexe (9) de sorte que l'incision complexe a une largeur W dans cette zone d'enfoncement.The invention relates to a tire comprising a tread (1). The tread (1) comprises a plurality of blocks (3) separated by grooves (5), each block (3) having a contact surface (7) intended to come into contact with a ground and at least one complex incision (9) Depth P and length L, each complex incision being delimited by two gum walls vis-à-vis. For at least one complex incision (9) of length L, each wall delimiting this complex incision comprises an alternation of bumps (11) and recesses (13) in the length L of this complex incision (9). The alternation of bumps (11) and recesses (13) extends from the contact surface (7) of the block (3) to a depth Pa less than the depth P of the complex incision. The alternations of bumps (11) and recesses (13) of the two walls delimiting the complex incision are complementary so that the space between these walls is generally constant in this zone of alternation. At least one wall delimiting the complex incision comprises, from the depth Pa, a depression (15), said depression extending in the length L of the complex incision (9) so that the complex incision has a W width in this driving area.
