자주 묻는 질문

What is wheel offset?

The distance in millimeters between the wheel's centerline (its true middle) and its mounting hub surface — positive offset pushes the wheel face outward less, negative offset more.

What is backspacing versus offset?

Backspacing measures from the back edge of the wheel to the mounting surface; offset measures from the wheel's centerline — they describe the same wheel geometry from different reference points.

What inputs does the Wheel Offset Calculator need?

You'll need to provide: Wheel width (in), Offset (mm). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.

How accurate is the Wheel Offset Calculator?

The Wheel Offset Calculator applies the formula exactly as calculated — Backspacing (in) = wheel width(in)/2 + offset(mm)/25.4. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.

Is the Wheel Offset Calculator free to use?

Yes, the Wheel Offset Calculator is completely free, requires no signup, and runs instantly in your browser.
