my car initially had an 18" rim with a zero offset (in case I'm wrong about that offset number, what I mean is that the tire stuck out past the fender by about a 1/2". It has the factory lowering springs. The tires rubbed horribly on the body. Any bump or body lean would cause this. We switched to a different rim, same size but with an offset that pulled the rim in (in other words, it's tucked) and no problems with rubbing. HTH!
