"The offset of a wheel is the distance from the mounting surface of the wheel to the true centerline of the rim. A positive offset means the mounting surface of the wheel is positioned in front of the true centerline of the rim / tire assembly. This in effect brings the tire in to the fender well more. Conversely, a negative offset means the mounting surface of the wheel is behind the true centerline of the rim / tire assembly. This will cause the tire to stick out away from the vehicle."

Basically if your offset is too high, your wheels will hit your brake calipers. If it's too low, then the wheels will stick out of your wheel wells, and you'll need longer lug nuts or something. I'm just deducing this from the definition above, someone more experienced wanna chime in?
