I don't know of simpler an better. There are probably better, but the used tire is about as simple as it gets. I have hauled several engines on an old tire and it has always worked well. I hauled one on a wooden stand that crate motors come on and kept having to tighten it down because of vibration. The screws holding it together started pulling out so I stopped in the middle of South Dakota and begged a service station for a junk tire, tipped the engine over onto the tire and tied it down. The engine stayed tight and in place the rest of the trip.
