Something else to consider here is that when the rim size increases the amount of rubber decreases. I've read, but don't have any factual information to back it up at this point, that rubber weighs more than aluminium. If that is true, a larger lightweight aluminum wheel should have a notable effect. It would be worth looking up the weights of the tires too, if there is somewhere that they're published. It's all a balancing act.
