Wheel Offset Explained

Understanding wheel offset is crucial when upgrading the wheels on your 2008 Lexus IS250 AWD. The offset is the distance between the wheel's mounting surface (where it bolts to the hub) and its center line. It's measured in millimeters and can be positive, negative, or zero. A positive offset means the mounting surface is closer to the outside of the wheel, pushing the wheel inward towards the suspension. A negative offset means the mounting surface is closer to the inside of the wheel, pushing the wheel outward away from the suspension. A zero offset means the mounting surface is exactly in line with the center of the wheel. The correct offset is essential for ensuring that the wheel sits properly within the wheel well and doesn't rub against the suspension components or the fenders. It also affects the car's handling and stability. Changing the offset can alter the scrub radius, which is the distance between the steering axis and the center of the tire contact patch.
