What I find interesting is, my biggest question for this thread was in regard to the diameter of wheels, thus the thread title. I knew that gearing could nominalize torque and speed differences so I believed there had to be other reasons for making a size selection. Asking the question about width was actually a side note, yet it has become the main topic of discussion, and I welcome that!

Please keep the conversation going, there has been a HUGE amount of good information presented.

I really would love to see some data that supports the anecdotal evidence because that is where there "appears" to be discrepancies with physics. My guess is that actual data will support the physics, when ALL variables are accounted for.
