Abstract

L’invention concerne un pneumatique du type HIGH LOAD CAPACITY pour véhicule de tourisme comprenant une surface lisse de référence (44) et au moins un élément moulé en creux (46) et/ou au moins un élément moulé en proéminence par rapport à la surface lisse de référence (44). Une épaisseur maximale Emax, la profondeur maximale Pmax de chaque élément moulé en creux (46) et/ou la hauteur maximale Hmax de chaque élément moulé en proéminence vérifient Emax^(0.4) x Pmax ≤ 1,1 et Emax^(0.4) x Hmax ≤ 1,1, Pmax et Hmax étant exprimés en mm. Emax est la distance maximale entre la couche renforcée axialement la plus extérieure (36) et la surface lisse de référence (44). Figure pour l’abrégé : Fig 3
