Cook until rib roast reaches an internal temperature of 120 degrees F. (or your desired temperature). Remove from oven, cover loosely with aluminum foil, and let sit approximately 15 to 20 minutes. Cutting into the meat too early will cause a significant loss of juice. Do not skip the resting stage.
Even a 12 pound rib roast will take 6 to 8 hours at that temp, and a rib roast is much thinner. A whole 55 pound, basically spherical roast will take far longer at 190. 24 hours maybe. You're much better off starting it a day in advance, monitoring it carefully, and if perchance, it happens to come up to temp before you're ready, just hold it in a much lower oven.
