Problems turning

Since surface area has no bearing on friction, I would assume that this would be a bad Idea. By putting the two "sticky" wheels beside each other, you are reducing the amount that the wheel has to be pulled sideways when turning, and increasing the amount that it rolls along the turn. This decreases over all turning friction.

If you were to place them on opposite corners, it would do nothing to the amount that the sticky wheels have to be pulled sideways to follow the circle of your turning radius, and since One wheel has the same amount of friction as two, I wouldn't expect this to solve your problem at all.
