Abstract

La présente invention a pour objet un pneumatique (1) pour véhicule lourd de génie civil et vise à améliorer le compromis de performances entre sa durée de vie en usure, sa résistance aux agressions et son adhérence. La bande de roulement (2) ayant une largeur axiale L0 et comprenant, de chaque côté d’un plan équatorial (XZ), au moins une découpure longitudinale extérieure (41) à une distance axiale LE au moins égale à 0.5*L0/2, et au moins une découpure longitudinale intérieure (42) à une distance axiale LI au plus égale à 0.4*L0/2, la au moins une découpure longitudinale extérieure (41) comprend une portion radiale extérieure (411) débouchant sur la surface de roulement (3) et ayant une largeur moyenne WE1 au moins égale à 0.6 fois sa hauteur HE1, et la au moins une découpure longitudinale intérieure (42) comprend une portion radiale intérieure (422) ne débouchant pas sur la surface de roulement (3) et ayant une largeur moyenne WI2 au moins égale à 0.6 fois sa hauteur HI2.
