On our team, I have voted for 4 wheels, each side driven by a motor. We have another contingent that wanted to have 8 wheels (2 in each corner). I say that won't help traction (for reasons stated above) and will make turning even harder because now you have two wheels locked together so one will have to slip in the direction of rotation during turns. It would be better to have three to a side, since the center wheel would take weight off the outside ones and help the robot to turn, but that complicates the drive train and we are running out of time.
