If you are using textured tread, you will get more traction with the carpet using a wider wheel. The effect is not huge compared to changing robot weight, but it is very real. Also all friction materials have a maximum power transference capacity for a given surface area, if you exceed that you will burn rubber and prematurely wear your wheels. A wider wheel will wear slower which keeps more tread longer, which means more overall traction.
