Combine all the spice rub ingredients in a small bowl. Set aside.
About 1/2 hour before you’re ready to grill, remove the ribs from the fridge, pat them dry and let them come to room temperature. Prepare grill for direct grilling and let it get good and hot.
About 10 minutes before you’re ready to grill, brush the ribs with olive oil. Sprinkle generously with the spice rub and, using your fingers, rub the seasoning into the meat.
Lightly oil the grill grates and place the ribs directly over the heat. Close grill and cook ribs for about 15 minutes, turning them every 5 minutes. Move them to different parts of the grill if some are cooking up too fast, getting overly charred. Check internal temperature with an instant-read thermometer; temperature should be at least 140ºF. Continue cooking as needed, but don’t overcook.
Transfer to a platter and let them rest for about 5 minutes. Serve.
