What is wheel offset? Very simply stated, it is the distance from the hub mounting surface to the centerline of the wheel. It is measured in millimeters and can fall into one of three categories:
Zero wheel offset occurs when the hub mounting surface is spot-on with the centerline of the wheel. Positive wheel offset occurs when the hub mounting surface is positioned toward the front of (or, wheel side) of the wheel. On the other hand, if the hub mounting surface is positioned toward the brake side of the wheel, then we call it negative wheel offset.
Wheel offset directly affects the way a car handles. Therefore, if the offset of a wheel isn't correct for the particular vehicle, problems will ensue. At Tire Rack, we test fit thousands of vehicles for proper fitment to create an extensive database—we use that information to ensure the wheels you order fit the vehicle you drive.
