: OK I need sombody to explain somthing to me
: We want more traction so I tell our Engineer that we need wider wheels to put more area in contact with the ground. and he says no we would gain NOTHING out of it because the wheels would have less weight on each square inch.

I suggest that you should do some experimentation. Friction is not neccessarily a very intuitive thing, especially when you are working with carpet. I suggest trying lots of stuff.

On the wheel width thing we have found that some materials develop more traction with wider wheels, but some do not. If you want to demonstrate this to your engineer I suggest using the toothed side of some timing belt. (Tracked vehicles that use doublesided timing belt develop lots of traction.) If you are interested in how to set up a friction test, I would be more than happy to elaborate.
