Again let me stress that I don't pretend to be an expert.
As I understood what was explained to me, there are some rims which are
centered by and supported by the lug holes, but most modern rims are
actually centered by the hubs and only marginally supported by the lugs.
This info was passed along to me by my front end guy. While he is an
excellent and honest mechanic, I do accept that he could be wrong. He
showed me some examples of the ways that wheel/hub combinations fit
together, and I could definitely see why he would try to steer folks away
from aftermarket wheels, which are supported by and centered by the lugs.
He also told me that bored out steel rims actually breaking is an uncommon
event, but it happens often enough that he didn't feel he could recommend
the practice.
As for the old bug and bus wheels, the issue here was not the size of the
hole, but the amount of reinforcement provided by the curved steel lip.
(cross section _____/ \_____ as opposed to _____ _____,
where the spaces are the center holes of the rim where the hub fits through)
Don't know if I'm making sense here or not, but the bottom line is that this
is all irrelevant if you are dealing with the thicker cross section of an
alloy rim, anyway.
Hope that helped; I know that I feel better!
