Physical effect of less mass: Because the wheel is rotating while driving its mass has a mass moment of inertia and so an angular momentum. If you then move against the originally position the wheel its "resisting" against the movement ( force you feel if you move a spinning wheel, try it!;). Because of that, less weight in the wheels result in a lighter movement of the bike, which is especially important for tricks, where the BMX gets moved a lot.
