Roll-Tru Scale Models is happy to present its premier line of wheels which were designed for the discriminating HO scale modeler. 

Since Roll-Tru is run by modelers for modelers, it sought to fill a need that couldn't be filled anywhere else. In this particular case, Roll-Tru's modelers had many IHC, AHM, and Rivarossi passenger cars with those terrible plastic wheels and couldn't find acceptable metal wheels to fill in. Well, Roll-Tru solved this problem by creating the exact wheels necessary to directly replace the plastic horrors that have quickly filled the trashbins of modelers worldwide. 

There are three models designed specifically to replace all IHC, AHM, and Rivarossi wheels, including the pizza cutter-flanged 30 inch wheels. All wheels are turned from solid brass, plated in nickel, and then the nickel is blackened. Perfectly balanced, perfectly sized, these will roll true for the lifetime of your passenger cars and probably more.
