The steel wheels i have are lug centric, same as stock. They just use acorn nuts to self center. I'm rolling 33x12.5's on my 15x8 steel locks and they balanced out relatively well. I get a slight vibe from 50-60 mph but other than that smooth sailing.
I have been thinking about doing the bead thing. The shop I went to put Nitrogen or something in my tires instead of regular air. Said that it would not leak out as fast as regular air or whatever. I had never heard of such a thing, but whatever.
