When installing accessory wheels, be sure to install wheels with the proper offset. Measured across the width of the wheel rim, the offset is how far the center of the wheel is offset from the wheel mounting surface. The wheels on Volkswagens covered by this manual have negative offset. In other words, from the wheel mounting surface the wheel rim is offset to the inside. The use of other than original equipment wheels requires special care since many aftermarket wheels do not have the correct offset. Incorrect offset may cause the tires to interfere with the body, overload the wheel bearings, or affect the steering.
