The offset is the distance (in mm) between the center of the wheel and the mounting surface.
2. The larger the offset, the more the wheel will be "tucked" inside the wheel well.
3. The smaller the offset, the more the wheel will stick out towards the road.
4. A wheel can be installed on a car even if the initial offset is different. However, the difference in offset depends on each vehicle, depending on the available space on the axle.
