▎ 摘　　要

NOVELTY - The tire (1) has a rubber inner layer (5) facing the inner cavity (8) of a carcass. A cover film (7) made entirely of graphite or graphene is deposited on the inner surface (6) of the inner layer. USE - Tire. ADVANTAGE - The graphite or graphene cover film enhances impermeability, allowing the inner layer to be made thinner but with all benefits in terms and weight and rolling resistance. The same cover film also improves thermal stability, chemical resistance, and rubber compatibility, is environment friendly, and is achievable using simpler deposition techniques. The use of the cover film also eliminates need for specific impermeable layer such as inner liner. DESCRIPTION OF DRAWING(S) - The drawing shows the partial sectional view of a tire. Tire (1) Rubber inner layer (5) Surface (6) Cover film (7) Inner cavity (8)
