Tubes generally are made to fit a range of tire widths. Ideally, you want the tube to fit in the tire with no excess material to cause kinks and wrinkles which will just be wear to make a near future flat. And maybe a bumpy ride because air pressure isn't supporting the tire evenly.

On the other extreme, a tube that has to stretch and expand to fill the tire will tend to act like a balloon when punctured. So when flats happen, they'll be all at once instead of slow leaks that give you time to pick where you want to stop.
