Pat the steaks dry with paper towels and lightly season each side with a scant ½ teaspoon kosher salt; place uncovered in the refrigerator for a couple of hours or overnight.
Remove the steaks from the refrigerator and let them sit at room temperature for 1 hour before grilling.
Rub one cut half of a garlic clove over each steak; re-season both sides with additional kosher salt and freshly ground black pepper to taste.
Preheat your grill: prepare very hot coals or set a gas grill to high with the lid open.
Place the steaks on the hottest part of the grill and cook about 3–4 minutes per side for rare (approximately 8 minutes total). For cross-hatch marks, after 1½–2 minutes on a side, rotate the steak 45° and continue cooking the remainder of the time before flipping.
Repeat the same process on the other side, cooking a total of about 3–4 minutes for that side; check doneness with an instant-read thermometer and remove steaks at 120°F for rare or 125°F for medium-rare.
Transfer the steaks to a plate or cutting board and let them rest for 5 minutes before serving to allow carry-over cooking and juices to redistribute.
