I would assume they don't wear them that they have been infused with there very soul. As they are far more powerful than the average wraith they where infused with the power of the rings. The rings where only used to gain a "foothold" in there minds for sauron to grasp. I would assume that he no longer needs there rings to control them as corrupt as they are.
