Smoked Prime rib

Smoking a 18# prime rib tomorrow @ 250 how will take to get to 130?

What diameter is it? A 4 bone will take just as long to cook as a 7 bone if they are the same diameter. Figure about 30 mintues per inch + searing time.

It is 7.5 wide and 5.5 high. So cook it for about 4 hours?

It'd be closer to 3 hours. 5.5 inches is your smallest dimension. Here's a great write up from Meathead on Prime Rib. Lot of good info: http://amazingribs.com/recipes/beef/prime_rib_roast.html

I always smoke prime rib at 210 degrees and cook 20 minutes for each pound---so 18 pounds would be 6 hours at the lower temp that I use. However sometimes I cut the whole prime rib into smaller parts--cooking time then is much quicker and you will create more "end pieces" which many people want

Thanks for all the info. Smoked the best prime ever. Got it in a bit late 11:00 so I cooked it at 230 till 4:30 then bumped it to 250 till 5:00 to it out at 130. Pulled it covered with saran wrap and tin foil then into the cambro for a 1 1/2 hr drive. Everyone thought it was cooked to perfection. The guys are still talking about it around the office.

Have to be careful here. the only time cutting into smaller parts will result in less cook time is if you reduce the shortest dimension of the meat as Andy explained.

I really like Meathead's method in this video. I've tried several different methods and while they were all really good they could stand improvement. Cutting off the bone makes more sense to me than anything. I will be cooking mine by his method this year.
