You want to use aftermarket lug nuts on your steelies with hub caps?
Two things to consider.
1. Can't use tapered lugs on steelies. The seating of the lug is different and is not secure and would most likely come loose after driving over time.
b. The aftermarket lugs don't have that little lipped area that hold the hub cap in place. Sorry, not sure what it's called, or the proper terminology for it, but I think you get the idea of what I'm talking about.
