Prepare the grill and clean grill grates for cooking over medium-high heat or about 350°F to 450°F.
Pat the pork chops dry with a paper towel and brush both sides evenly with olive oil. Generously season the pork chops with the dry rub, patting into the meat on both sides. Rest for 5-10 minutes as the grill heats.
Grill the pork chops over direct heat, with the lid closed, until the pork chops are well-marked, for 8-12 minutes total, turning once. For juicy pork chops, the chops should still be barely pink in the middle and 140°F. Rest the chops for 5 minutes for the juices to set into the meat before cutting, and serve.
