What is the ET value of a wheel hub?

[Kathleen]

The ET value of a wheel hub refers to the Off-set value, which means the offset value. Here is more information about the ET value: 1. The offset value indicates the degree of deviation between the mounting surface of the wheel hub and the centerline of the rim, which can be positive, zero, or negative. The impact of changing the Off-set value: If a rim with a smaller positive Off-set value is used, the wheel track will be widened, thereby reducing the transfer of the vehicle's center of gravity during cornering and improving the cornering speed limit of the vehicle. 2. The larger the ET value, the more the rim will retract into the wheel arch; conversely, the smaller the ET value, the more the rim will extend beyond the wheel arch. The ET value can be positive or negative. Generally, the ET value of rims for passenger cars is usually positive, and only a few models, especially four-wheel-drive vehicles, will adopt a negative Offset value.
