Abstract: A trunk liner is disclosed for an automobile trunk compartment of the type having a spare tire well recessed in a medial floor area of the comparmtent. The trunk liner is formed of fibrous material and molded to form a relatively stiff body having a center floor cover panel and a plurality of panels extending unwardly along the sides of the center floor cover panel and integrally connected thereto, and a recessed spare tire well liner integral with and extending downwardly from a medial portion of the center floor cover panel. The stiffness of the molded fibrous body and the outwardly diverging relationship of the plurality of panels permit the panels to resiliently engage inner wall surfaces of the trunk when the panels are biased inwardly toward an upright position when mounted in the trunk. A separately formed cover for the spare tire well liner is provided, with the trunk liner having a relatively narrow molded ledge extending around the spare tire well liner for receiving the cover in proper position.
