This reminds me of an article I've read on last month's issue of car and driver (i think..), where they tested out various diameters and widths of wheels on the skidpad. When they were testing out wheels of different widths but the same diameter, the traction initially improved as they moved up from the thinnest tire up, as expected. But from a certain point the trend began to reverse. Tires of wider than optimal widths started inducing understeer, and the wider they got the more understeer they caused. The engineers of michelin (maybe goodyear, don't remember clearly) explained that this happened because with the excessively wide tires the outside wheels gained more traction, dragging the car outwards on turns.
