What is Wheel Offset?
Wheel offset (ET value) is the distance from the wheel's mounting surface to the centerline of the wheel. It's a critical parameter that determines the wheel's position within the wheel well, directly affecting vehicle handling, stability, and appearance.
Key Components
- Offset (ET value): Distance from mounting surface to centerline
- Wheel width: Affects tire contact patch and appearance
- Mounting surface: The flat surface that contacts the wheel hub
- Centerline: The geometric center of the wheel width
Why It Matters
Proper wheel offset ensures tires don't interfere with body components, maintains appropriate track width, and preserves vehicle handling and safety. Incorrect offset can lead to tire wear, suspension damage, or safety hazards.
