Another consideration, if you're racing, on the road, aerodynamics plays more of a part than rolling resistance usually, so I would run a skinnier front tyre for better aero and a fatter rear tyre for better rolling resistance (and because the rear tyre is hidden by the frame and make less difference to aero)
