dually wheels

[rjn72]

I have a 1987 v30 crew cab dually. My question is, Will dual wheels interchange between Ford, dodge, GM, etc. It is a new truck to me and I am looking at buying tires. I found a set of new tires mounted on 16.5 wheels, but the wheels are on an 81 Ford dually. My wheels ar 16, so the tires do me no good unless I can use the wheels also. I bought the truck because it was a sweet deal, but I don't have any experience with duallys. Thanks in advance for the help.
