Old military w200

I recently aquired a former military 3/4 dodge with 8 lug 16.5 tires. I am wondering if anyone can tell me what I can take wheels off of that may have a more common tire size not sure what matches the bolt pattern would like 15" or 16" tires

not sure what bolt circle diameter you have but here is a link for some with a 6.5" bolt circle.
