​Make your own tire machine, Buy a cheap drill press, about $60.00 and a 3" cross slide vise from e-bay $36.00, glue some sand paper on a block of wood then clamp in the vise, chuck a 3/32 axel in the drill, then fasten your tire to it,  so there you have it.

Billy I love people that think like that!  Or at least think.

 

Try this.  Clamp a piece of wood square to the table like you did.  Then make a wedge shape like a big long door stop with a flat and a handle and glue your paper to it.  Then use the first piece as a fence & slide the tapered part against the piece clamped to the table & with a little messing around you could get close on size.  No slide needed.

 

NOTE Drill presses are not very tight or designed for side pressure and it will wear them out faster.

Billy, years before CAD programs existed, a guy put a drawing of what you describe above, on OWH. His block of wood was two  hinged pieces  of 1 by material with a threaded rod so he could vary diameters. He used drywall sanding screen (100 grit?) to cut the rubber .IIRC, this guy was from western Pennsylvania.

​Instead of running the slide back and forth to true the tire, you could work the drill press up and down while you feed the sanding block in.

Even good drill presses have a bunch of runout.

Get a Lovejoy coupling to fit your motor shaft, then build a couple of pillow blocks to hold the tire turning shaft. You will take out any vibration with the coupling . You can get all sorts of different sizes and configurations for the Lovejoy stuff. No belt drive required and it remains fairly small.

 I used them when I built my GoKart engine dyno.
