What is the difference between zero-offset and negative-offset wheels?

[AlejandroAnn]

Here are the differences between zero-offset and negative-offset wheels: 1. Force distribution: When the force-bearing surface of the wheel is outside the center reference plane (from the installed perspective), it is a positive-offset wheel (most factory-installed wheels are positive-offset). Positive-offset wheels offer advantages in safety, stability, and since they are tucked inside the vehicle body, they don't create additional air resistance. Conversely, when the force-bearing surface is inside the center reference plane, it is a negative-offset wheel. 2. Stability: The benefit of negative-offset wheels is that they widen the track width, providing better vehicle stability and allowing better utilization of high-performance tires' lateral support capability. However, negative-offset wheels typically protrude outside the vehicle body, creating some additional air resistance and being more prone to scraping against external objects. 3. Numerical values: Wheel offset is often denoted as ETxx, where ET+30 means an offset of +3cm; ET-30 means an offset of -3cm. Generally, the maximum positive offset is +50, while the maximum negative offset is -44.
