Patent ID: 7066228

Claim:
A tire incorporating a metal and rubber composite comprising a rubber matrix reinforced with a metallic body adhering to the rubber matrix by means of an adhesive interphase, characterized by the following features: a) the rubber matrix is based on diene elastomer; b) the metal is a carbon steel, the carbon content of which is between 0.35% and 1.20% by weight; c) to constitute the adhesive interphase, this carbon steel is coated with an intermediate metallic layer bearing aluminum oxides or hydroxides, which itself is covered with an organosilane film providing, as coupling agent, the bond between the aluminum oxides or hydroxides on one hand, and the rubber matrix, wherein the tire includes a carcass reinforcement, the composite being present in the carcass reinforcement of the tire, and wherein the rubber composition of the composite has, in the vulcanized state, a secant tensile modulus, at 10% elongation, which is less than 9 MPa.
