[0002] The offset of a car tire is the distance between the centerline of the wheel side and the actual contact surface between the wheel and the hub, that is, the offset value. Generally, after upgrading the rim, the wheelbase will change accordingly according to the difference in rim width and the change in offset. If the rim is upgraded, it is necessary to consider whether the wheel will interfere with the shock absorber and suspension parts on the inside and the fender on the outside. Therefore, for car tire modification, offset is a very important parameter indicator. Existing measurement tools are relatively simple and have low measurement accuracy. Utility Model Content
