What does wheel offset mean?

[Cameron]

Wheel offset refers to the distance from the inner mounting surface (mounting face) of the wheel to its centerline, which can be categorized as positive offset, negative offset, or zero offset. Characteristics and applications of negative offset: Negative offset means the mounting face is positioned inward (toward the brake system) relative to the wheel centerline. "Deep-dish" style wheels often have negative offset, commonly seen in SUV models and some BMW vehicles. Characteristics of zero offset: Zero offset means the two surfaces coincide. Characteristics and applications of positive offset: Positive offset means the mounting face is positioned outward. Wheels with positive offset are typically used in front-wheel-drive and some rear-wheel-drive vehicles.
