Where to Check the ET Value of the Wheel Hub?

[VanLuna]

The ET value of the wheel hub can be found on the back of the hub, either engraved or on the cardboard box, with detailed parameters listed on the label. The ET value, also known as the ET offset value, refers to the offset, which is the deviation between the mounting surface of the wheel hub and the centerline of the wheel rim, measured in millimeters. There are three types: positive, zero, and negative. Offset is defined as the distance between the mounting surface of the wheel rim and the center of the wheel rim. A positive value indicates an outward direction, while a negative value indicates an inward direction. The wheel hub is the rotating part of the wheel steel inside the tire, connected by columns to the wheel core, which is the metal component supporting the tire and mounted on the axle. It is also called the wheel rim, steel rim, or tire ring. Wheel hubs come in various types based on diameter, width, manufacturing method, and material.
