There is nothing wrong with the rim being supported by the lugs, it's called lug centric. My 93 has lug centric wheels as does my van, factory installed.

Okay - that really surprises me since GM tends to standardize parts as much as possible. So nothing I said applies to 5 hole rims. Sorry!
I've been scared to run the rims that I had the centers cut out of on my 89 K1500 that I bought later. One of them is a basket for tire chains, one is sitting out in my junkpile, and the others I hauled up on the hill and filled the back side with rocks and used them to support fence posts where the ground is too hard to dig or drive in a post.
So I suppose that I could mount an old tire on one of them and use it for an extra spare since we live way out of town...?
