Why are the walls of the bronchioles folded?
Those foldings are called as mucosal folds, formed by the contraction of smooth muscles , are also present in trachea, and in many other organs such as gallbladder etc.
Physiologically: This folding causes an increase in area for better action of mucus which protects the body from entry of dirt, pathogens and loosing the moisture.
Anaomically: as @Bryan pointed out that the folding permits the contraction and relaxation of smooth muscles around the bronchioles.

This is the best answer so far, but it would be much improved if you can find some references to support what you say to make it clear that this is the correct answer.More
