A tire assembly comprising an assembly of uncured components is disclosed. The assembly of uncured components includes a circumferential uncured internal composite comprising a combination of at least one uncured layer (6A, 6B) of a metal cord reinforcement containing rubber composition with a sulfur content of at least 2.5 phr and at least one adjoining auxiliary buffer layer (11 A, 11B, 11 C) of uncured rubber without cord reinforcement and having a sulfur content of at least 1 phr less than the sulfur content of the metal cord reinforcement containing rubber composition. The uncured internal composite is positioned between an outer circumferential uncured tread (2) and a supporting inner uncured carcass (7). Also, a tire comprising a sulfur cured tire assembly is disclosed.
