Ah, stability? Again, not determined by surface area. It's determined by some other things, like CG and wheelbase.

Let's say you have a rectangular robot at max dimensions, with the wheels (or treads) a little bit inside the max. It looks like this:

That's the wheelbase as seen from the top. As long as you keep your CG above that area, you won't tip. As soon as the CG goes outside that area, you've got a split second to get it back before the big crash. If you have treads, you'll still have the same area.
