Sorry, typo there. I would only consider a spinner with double wheels at all four corners.

If you plan to be rolling over gravel or dirt though, I would avoid spinners altogether. For "off road" reliability (with wheels) I'd get a two-wheeler, preferably with larger diameter wheels. Larger wheels should soak up bumps better - all else being equal. I'd also want those wheels to be easily field replaceable.

Buy you would probably do better to avoid wheels altogether if not on hard / smooth / paved surfaces.
