center bore on wheels is too big

aren't the metal rings that are used aluminum? those shouldn't rust anyway.

The rings won't rust but through galvanic corrosion they will attach themselves to the hubs. I had a set of aluminum rings in my Volk TE-37 on my Miata. I did not buy the caps so eventually one of the rings "welded" itself to the hub. It took about half an hour with a hammer and chisel to finally pry it off.

After that experience, I took a closer look at the rings, and IMO, they are totally unnecessary. Tapered lugs will center your wheels fine. Shanked lugs will center your wheels fine. If your wheels are made so badly that the lugs do not center the wheel, adding rings won't help since, if you install metal hub centering rings, the lugs will no longer seat correctly.

On my Volks, the lugs center the wheel so perfectly that when the lugs are torqued down, the hub centering ring is loose in the bore and can be spun inside the bore with my finger. You're better off spending the money buying the center caps (if they aren't included); then you won't get water in there causing the brake hat or drum to rust to the hub.
