Yes,
the military wheels and tires do fit the big bolts.
My son has an old 1971 Chevy C50 flatbed that he bought military tires and wheels for in order to get rid of the old tires and widow maker wheels. They fit the rear perfectly in the 9.00X20 size.
The reason I am searching here now is because the military wheels are a little too wide for the front end, they rub on the tie rod end.
Can anyone reccommend a wheel type that will fit the front that is not quite as wide that will take modern day rubber?
He is not worried about the tube vs. tubeless, the truck will get limited use mainly around town.
