Abstract
Pneumatique radial (1) ayant un diamètre de jante au moins égal à 24 pouces et une charge nominale au moins égale à 8 000 Kg pour un véhicule minier, comprenant une bande de roulement (22) d’épaisseur radiale E au moins égale à 0.04 fois le rayon extérieur du pneumatique. La bande de roulement (2) comprend au moins deux compositions de caoutchouc, composant au moins 90% de l’épaisseur E. La première composition (221), radialement intérieure à la deuxième composition (222) compose au moins 40 % et au plus 66% de l’épaisseur E ; elle a un module d’extension sécant à 10 % de déformation, à 23° C, supérieur à 5.2 MPa, un allongement à rupture à 100°C supérieur à 500%, et une perte dynamique maximale à 100°C et 10 Hz supérieur à 0,13. Le taux en masse exprimé en pce de charge de la deuxième composition (222) est supérieur au taux en masse exprimé en pce de charge de la première composition (221). Figure d’abrégé : figure 1
