Centre Caps

The two basic types of centre caps are either inserted from the back or attached from the front. For the type that is inserted from the back, always make sure the flange of the cap matches the wheel's chamfer and is below the mounting surface of the wheel. If the flange of the cap protrudes beyond the mounting surface of the wheel, it will not let the wheel seat properly. If this happens, it will give you a false torque beyond the mounting surface of the wheel, it will not let the wheel seat properly. If this happens, it will give you a false torque reading and the lug reading and the lug nuts will become loose, resulting in wheel failure and possibly causing serious injury.
