Another bit of tread fun, this time with the rubber ones from the Granite Grinder. 1x2 tiles fit perfectly over the raised portions. It can still roll freely, and the tiles remain in place. They also give it rigidity if you try to bend the ring inward.
I've actually had this sitting around since before I got any power miners, but now I have tons of these treads, so I may have to do something with it.
