The offset of a wheel is the measured distance between the hub mounting surface and the center line of the rim. Below is an explanation of the various types of offsets.
A positive offset occurs when the hub mounting surface is on the street side (the side you see) of the center line of the rim. Most factory rims will have this type of offset.
When the hub mounting surface is centered within the rim, it is known as a zero offset.
If the hub mounting surface is on the brake side of the centerline of the rim, it is considered a negative offset or “deep dish”.
Please feel free to drop by or phone a store near you if you require additional facts about wheel alignment and balancing offsets.
