This is a super late response, but I did this with a set of Mercedes wheels with nice snow tires on them.
I went to harbor freight, bought their oversize drill bit set, and used the closest size to the bolts. The mercedes wheels also used 12mm ball radius on the lug bolts, so I had to buy new lug bolts with 12mm balls and 14mm bolt dimensions.
They sure do make these wheel interactions with the vehicle complicated: centering rings, lug bolt diameters and lengths, ball seat dimensions, Einpresstiefe, etc, etc
