If you’ve ever wondered why some wheels sit flush while others poke out past the fenders, the answer usually comes down to wheel offset.
Wheel offset measures the distance between the centerline of the wheel and the mounting surface (the part that bolts to your vehicle’s hub). This measurement determines whether your wheel sits further inward, further outward, or directly centered.
There are three possible types of offset:
-
Positive Offset – The mounting surface is positioned toward the outside of the wheel, causing the wheel to sit further inside the wheel well.
-
Zero Offset (0mm) – The mounting surface aligns exactly with the centerline of the wheel.
-
Negative Offset – The mounting surface sits toward the inside of the wheel, pushing the wheel outward toward the fender.
If the offset of your new wheel is lower than your vehicle’s stock offset range, the wheel will stick out further than your factory setup. And the lower the offset number, the more aggressive the outward stance becomes.
You can usually find the offset stamped on the backside of a wheel spoke, often labeled with “ET” followed by a number (for example, ET-12 or ET20). That number tells you exactly how the wheel will sit compared to center.
Choosing the right offset helps you achieve the look you want while maintaining proper clearance and fitment. If you’re unsure what works best for your vehicle, it’s always a good idea to double-check before installing.
