Bullitt Wheels - How to open up bore?

Just use good shank lug nuts. Nice fitting and all that. The stamped steel acorn lug nuts were self centering, the shank nuts need to be the right size to fit the rims. Even some AL rims use an acorn style lug nut (thought they would start to crack?) but the 2012 Dodge Caravan I have uses 'em. But they use the STUPID 18mm metric with the cheesy metal cap on them to make them 3/4..and those damn things always deform.
