Two, how are you going to keep the rollers on? I mean, you can't just stick an axle through and say "stay" and have them stay on the axle. You need something hard on the outside, but how do you do that and not have to replace the whole tread?

Three, how much weight will this have? If it's too heavy, you might consider just wrapping the whole thing around a wheel for less weight.
I dont think this would bounce more then a tread and i don't think it would necisarily break. Look at most robots, none have suspension yet they arent (always) falling apart. Since i haven't tested it I can't speak to the reality of this answer.

I was thinking of using faerie dust. Agian this is me using AutoCAD agian after two years. No i intend a central shaft or even two triangle mounting plates on either side with a central core.

Well.... this idea hasn't been built yet, but... take an average tread design and add 2-3 pounds.
