Combine all of the dry rub ingredients in a bowl and mix thoroughly.
Preheat the grill on low heat for 15 minutes. I use a propane grill, you will need more time to preheat if using a charcoal grill.
Pull the ribs from the refrigerator for 15 minutes before grilling so the meat doesn't get shocked when placed on the heat. Remove the ribs from the package and then pull the membrane off the back of the ribs and discard it.
Rub all sides of the ribs with the dry rub. You will have extra so be sure to use one hand to sprinkle the rub over the meat and the other to rub it in. This will ensure that you don't contaminate the rub.
Place the ribs on the grill with the meat side down. Cover the grill and cook the ribs for 45 minutes.
Brush with the barbecue sauce and then flip the ribs over before brushing with more barbecue sauce. Cook the ribs bone side down for 10 to 15 minutes.
Remove from the grill and cover loosely with foil on a sheetpan. Rest the ribs for 10 to 15 minutes.
Slice into 1 or 2 bone sections and serve warm with more barbecue sauce on the side.
Nutritional information uses half of the dry rub recipe above and 1 cup of barbecue sauce.
