Spacers with stock wheels?
 

Hey guys, My truck is on factory 20" wheels, I'm looking at a set of hub-centric 2" spacers, Are they compatible or can you not use spacers with stock rims? would i need different lugs? or can i even run "acorn" style lugs on these? Sorry if this seems like a stupid question, been trying to find an answer and couldn't find anything for sure.
