Where is the wheel ET value usually indicated?

[VanCody]

The wheel ET value is typically engraved on the back of the wheel hub or printed on the packaging box/label with detailed parameters. The ET value, also known as the ET offset value, refers to the Off-set value (i.e., offset), which indicates the deviation between the wheel hub mounting surface and the centerline of the rim, measured in millimeters (MM). It can be positive, zero, or negative. Detailed explanation below: 1. Definition of Off-set: Off-set is defined as the distance between the wheel's mounting surface and the center of the rim. A positive offset indicates outward deviation, while a negative offset indicates inward deviation. 2. Impact of changing Off-set: Using wheels with a smaller positive Off-set value widens the track width, reducing body roll during cornering and improving cornering speed limits. However, this also increases the distance between the steering axis center and the tire center, making steering more difficult and increasing the load on steering components, leading to greater deformation of steering linkages. Therefore, appropriate Toe-in adjustments are required for correction.
