Would the number of wheels make a difference?

If you'd look at JVN's Mechanical Design Calculator, you can see the effects of gear ratio, # of wheels, # of motors, etc. on the effective pushing power of a robot. It allows for easy "prototyping", as the numbers are as simple to change as the push of a button.
I would defer the mathematical explanation to somebody of more knowledge, but for starters you can look at the formulas that he uses in this spreadsheet. JVN's Design Calculator may be found here:
