Skinnier tires are going to be faster, because they weigh considerably less. Tire weight isn't the same as the weight of other components, either; it's much more important, because your tires (along with the rest of your wheels) spin quite speedily. Breaking the inertia of a heavier tire/wheel will be harder, because that's how physics works.

If there's anywhere on your bike you want to keep the weight down, it's the bits that move, ie. wheels, tires, and to a lesser degree cranks.
