Apparatus usable with a tire changing machine (10) includes a protective arm (28) that may be pivoted about a shaft (36) having an axis that is generally parallel to the radial axis of the wheel and tire assembly (22) when positioned in the tire changing machine. Pivoting of the arm permits the second section of the arm to be adjacent, and substantially parallel, to the circumferential surface of the tire and the first section to be adjacent, and substantially parallel, to the side wall surface of the tire. The arm thereby forms a safety barrier against the release of components of the wheel and tire assembly.
