7. A radial tire with multiple integral protection functions according to claim 6, characterized in that: The tire blank preparation method adopts a radial tire two-drum forming method to form the tire, and increases the tension of the turn-up rod during the turn-up process to prevent the composite sidewall width from decreasing. The tire preparation method is to send the tire blank into a vulcanization mold, and vulcanize it in a vulcanizer to form a radial tire with multiple overall protection functions.
