There are a least four differnt styles of big bolt rim made during the years.
three piece lite duty
two piece, outside split
center split two peice,also known as a widow maker
three peice heavy duty
The above are all budd style wheels, there are also some dayton styled one that use a true split outer ring. There are quicker to pop off than the budd ones.
The heavy and lite duty three pc ones are pretty safe and very common. The two pc outside split is ok, but you have to make sure it not rust out or pitted bad. The widow maker is outlawed in most place here. The best thing you could do with it is send them to the scrap yard. If you dont know how or only think you know how to repair one of these wheel, DON"T touch them. Send them to a dealer and let them use the a cage to work on them. Count less people every yr get hurt by these rims, dont add to the list. Even the split ones from the smaller trucks can come back to get you.
