Understanding Wheel Offset

Whether this is your first time buying a set of wheels, or you're just wondering what all of the numbers on the back of a wheel mean, you're in the right place. We'll cover what all of the numbers on wheels mean as well as what wheel offset and backspacing mean.

What is Wheel Offset? Offset is the distance between the hub mounting surface and the centerline of the wheel. This measurement directly impacts your wheel fitment and the look of your vehicle.

What is the Centerline? It's found by measuring between the bead seats on the wheel. The centerline is the midpoint between these seats, which is used to calculate offset.

How is Offset Calculated? Measure from the hub mounting surface to the centerline of the wheel. If they’re aligned, your offset is 0. It’s measured in millimeters.

Positive Offset: If the hub surface is in front of the centerline (towards the wheel face), you have a positive offset. For example, +23mm means it’s 23mm forward. Too much can interfere with suspension or brakes.

Negative Offset: Common in aggressive setups. If the hub surface is behind the centerline, you get a negative offset. -44mm means it’s 44mm toward the back. Excessive negative offset may cause handling issues or added suspension stress.

Dialing in the right offset is crucial for a balanced, safe, and stylish setup. Use this knowledge to find the best fitment for your ride.
