Prepare grill for indirect grilling with a large dripping pan under where the roast will be. Aim for a grill temperature around 375 degrees F.
Periodically add water to the pan to keep the drippings from burning away if you want to make gravy. Make sure you know the weight of your prime rib. Plan on grilling indirectly for 12 to 14 minutes per pound.
If you are using a smaller roast, adjust the ingredients and cooking times accordingly.
