I saw the machine and the issue. Machines are neat. They have 2 different types of no-mar machines. They wont use the one type because of the warning on the wheels. The other one, with all the adapters that come with it, cannot clamp and prevent the wheel from spinning. The geometry of this wheel upside down didnt figure in the machines playbook. I guess deep wheels, like me, are just an anachronism today. Every contact component on the machine is an advanced polymer. Put the tire on the shelf, load the wheel, stand back and watch. Gotta see if i can figure out and start to make an adapter tonight if i can find material.
