Meanwhile, lightly coat the grill rack with oil and heat to medium-high (400 to 450 degrees).
Place the cobs in a shallow dish and coat with olive oil on all sides. Then, sprinkle the dry rub over the top, coating all sides.
Wrap each corn cob individually in a sheet of heavy-duty aluminum foil. Place a pat of butter in each. Loosely wrap the foil around the corn, leaving space between the cob and the foil. Seal the edges securely.
Place the foil-wrapped ears of corn on the grill with the sealed edge up. Close the grill and cook for 15 to 20 minutes, turning frequently.
Open the packets carefully to let the steam release. Garnish as desired as and serve!
