Wheel offset is a core parameter that determines wheel fitment, vehicle stability, and tire clearance. Accurate offset measurement is essential for replacing, upgrading, and customizing alloy wheels, steel wheels, truck wheels, SUV wheels, trailer wheels, tractor wheels, engineering wheels, forklift wheels and other automotive and industrial wheel products, avoiding rubbing, abnormal tire wear and driving safety hazards.
Wheel offset (also known as ET value) refers to the vertical distance between the wheel hub mounting surface and the wheel centerline, measured in millimeters. It is divided into positive offset, zero offset and negative offset, which matches different vehicle models and installation scenarios.
Simple & Accurate Wheel Offset Measurement Steps
First, place the wheel flat on a level surface with the outer rim facing down. Use a straightedge to cover the inner flange of the wheel, then measure the total width of the wheel rim and calculate the wheel centerline (total width ÷ 2). Next, measure the vertical distance from the straightedge to the hub mounting surface. Finally, calculate the offset value with the formula: Offset = Mounting Surface Distance – Wheel Centerline Distance.
A positive offset means the mounting surface is outside the wheel centerline, suitable for most passenger car wheels; a negative offset means the mounting surface is inside the centerline, commonly used for off-road truck wheels and modified SUV wheels; zero offset indicates the mounting surface coincides with the wheel centerline.
