An apparatus and method for conveniently servicing an elevator roller guide wheel assembly by replacing the tires thereof is provided. The preferred embodiment of the present invention comprises a three-component removable roller guide tire assembly in which the removable tire portion is interconnected with a hub plate portion. A flange plate portion is then interconnected with the joinder of the said tire and hub plate portions of the assembly. The roller guide tire assembly is comprised preferably of a dual durometer matrix of polyurethane to provide the necessary wear and pressure resistance properties thereof. Each of these three plate portions is molded with a metal plate to sustain the requisite dimensions and tolerances of the apparatus. In accordance with the present invention, when usual repair and replacement of a tire in an elevator roller guide assembly is required, only the tire is replaced instead of the entire wheel assembly.
