JConcepts Tire Break-In Drill Adaptor Kit (Black) (12mm/17mm)

This thing is worth every penny. I use this thing CONSTANTLY. On dirt tracks I use it to clean off tires. I chuck it up in my drill, put my muddy tires on it, and turn it against my cleaning brush/bucket to clean tires. It even dries off-road tires, just give the drill a zip, the tire dries itself centrifugally. It will fit both 12mm and 17mm wheels, so 1/8 tires are no big deal. I also use it to break-in touring car tires and sand down used up off-road tires for slick tire indoor racing. It's also needed to scuff in indoor racing slicks. It holds tires straight, no wobble, and you get an even sanding down. ONE THING TO ADD: I had to use some loc-tite thread locker on the piece of threaded rod, as it came loose, but that's not a big deal. We can do things like that.
