The J value of the wheel hub refers to the width of the wheel hub section, while the ET value indicates the offset between the mounting surface of the wheel hub and the centerline of the rim. Below is an introduction to the ET value of the wheel hub: 1. Meaning: The ET value of the wheel hub refers to the offset between the mounting surface of the wheel hub and the centerline of the rim, also known as the offset. 2. Types of ET values: A zero-offset wheel hub means the mounting hole surface is located at the centerline of the wheel hub; a positive-offset wheel hub indicates the distance between the mounting surface and the center of the rim is towards the outer side; a negative-offset wheel hub means the distance between the mounting surface and the center of the rim is towards the inner side.
