Stack the charcoal to one side of the grill to ensure a smokey fire.
Combine all the ingredients for the rub and spoon onto both side of the ribs.
Place the ribs meat side down over the other side of the grill.
Smoke for 6-8 hours, depending on how hot coals are. The ribs are done when the meat begins to fall from the bone or the internal temperature reaches between 190 and 203F for maximum tenderness.
About 30 minutes prior to removing from grill, brush with pineapple sauce and move over direct heat. Serve hot with extra sauce.
