Those measurements don't match anything I know of.

If 8 lug on 6.5" bolt circle, measured center to center of directly opposite lug holes. Or measured center to center of adjacent lug holes is ~1.9" this is not a good way to measure/determine bolt circle diameter.
4.56" is smallest center bore I know of with an 8 lug pattern.
