Looking to increase offset for wheels in the rear. They stick out a little bit. Ran low profile 215/35/18 tire on it (wheels are 9.5") but it was too skinny, not my liking and thought it's not safe. Want to run Pirelli 225/40 on them but it rubs when going fast and it meets bumpy roads. So I guess maybe increasing the offset to maybe et42~45 will solve it. Problem is that shaving the center hub safe?
