Everyone's opinion will differ. I'm a strong believer in choosing your wheel to fit your design, not vice-versa. A completely flat-floored game like logomotion would be a good example of a game where a team could use four-inch wheels to save space and weight. Rebound Rumble, on the other hand, seemed to have called for larger wheels to make traversing the midfield barrier an easier task. Gearing also has a lot to do with wheel choice. In 2011, team 3556 used eight-inch wheels to achieve a theoretical maximum speed of around 17Ft/s but switched to six-inch wheels in 2012 to both lower their robot's speed and to increase the pushing power of their 'bot. This allowed their robot to handle the bridges and midfield barrier more easily.

I hope that this makes a little bit of sense, and helps answer your question. Feel free to correct anything that I said that may not be correct, or just seems nonsensical!
