A molded plastic dishwasher rack support structure includes a rack base portion with plastic walls extending around the perimeter edge. The rack base portion and walls are formed by a molding process, and include a plurality of cross channels extending between the opposite sides of the rack base portion and opposite side channels extending forwardly and rearwardly adjacent the sides of the rack base portion. Metal structural braces are inserted into the channels of the rack base portion. The rack is rollably supported in the tub of the dishwasher by a plurality of wheels each having a shaft extending through the adjacent side brace. The metal braces and wheels transfer the load of the objects in the rack to the tub of the dishwasher, thereby providing structural integrity for the rack. The braces are slidably movable with respect to one another to accommodate variances in the molding process. In alternate embodiments, the channels may be sealingly closed with a closure flap.
