Not sure of your question(s). Tire Truers are for mounted foam tires usually. Mounted foam tires means gluing the foam tire unto the plastic rim. I had used it to wear down new rubber tires so that grip would be better but really it was a quick fix thing. You wouldn't normally use the machine with a rubber tire.
This machine only works with the MR-02 rims out of the box. There was somebody in the mini-zracer.com forums that was going to make an AWD adapter, but most ppl backed out and he decided not to do it.
To use it, you pull off the end of the adapter, put the rim (one at a time, front/rear doesn't matter- you need to remove any bushings or bearings from the wheel first) onto the part of the adapter that is still attached to the machine and then put the end of the adapter back on. Start up the machine and then adjust screw to stop at the desired diameter that you want. This usually requires lots of starts and restarts to make sure you're down to the proper diameter that you want. Then once you're done the first tire, the 2nd is easy as you'll already adjusted the screw.
