Abstract: The present invention provides a process of manufacturing envelope integrated tire comprising steps of: (a) placing a tread, at least one carcass ply, at least one inner liner having an inner surface and an outer surface; (b) joining a semi-vulcanized envelope between a surface of carcass ply and said inner surface of inner liner; (c) joining said surface of carcass ply and the tread of the envelope integrated tire; (d) joining a strengthening fabric on a side wall of said envelope integrated tire; (e) wrapping a bead to connect the envelope integrated tire to a rim of a wheel; (f) pasting through adhesive, curing and vulcanizing said carcass ply, inner liner and semi-vulcanized envelope on the tread to form an envelope integrated tire; (g) injecting a fluid inside said envelope through at least one injection valve; (h) fixing said injection valve to avoid any kind of leakage.
