  • Publication number: 20080258537
    Abstract: A wheel balance weight includes a weight, an adhesive seal, a release coated paper, and a protrusion. The protrusion is made of at least a part of the release coated paper, is disposed along a longitudinal direction of the weight, protrudes parallelly to a widthwise direction of the weight beyond one of opposite widthwise ends of the adhesive seal, is located at least around a position, which corresponds to the weight's center of gravity, and is provided with a cut-off, which is placed at the position corresponding to the weight's center of gravity. The wheel balance weight demonstrates improved workability upon assemblage.
