Wheel Offset

The wheel’s offset is the distance from its hub-mounting surface to the centerline of the wheel. The offset of a wheel can be one of three settings:

  • Zero offset: The hub-mounting surface is even with the centerline of the wheel.
  • Positive offset: The hub-mounting surface is toward the front or wheel side of the wheel. Positive offset wheels are generally found on front-wheel drive cars.
  • Negative offset: The hub-mounting surface is toward the back or brake side of the wheel’s centerline. "Deep dish" wheels are typically negative offset.
Offset can be calculated by positioning the wheel on a flat surface and measuring its overall width. Subtract the backspace, and divide by two.

Offset = (Width – Backspace) ÷ 2
