Wheel Offset Calculator

About Wheel Offset Calculator

The Wheel Offset Calculator is a specialized automotive fitment utility designed to calculate changes in inner clearance and outer 'poke' when changing your wheel width or offset. Whether you're fitting aftermarket wheels for a better look or upgrading for performance, understanding how the new setup will sit relative to your suspension and fenders is critical for preventing rubbing. This tool provides a high-quality numerical comparison between your current and proposed setups. Built with a focus on speed and privacy, all your technical records and modification plans remain secure.

How to use Wheel Offset Calculator

1. Enter the 'Width' and 'Offset' (ET) of your 'Current Wheel' and your 'Proposed New Wheel' into the provided input fields on the interface.
2. The calculator will instantly display the 'Fitment Results', showing the exact change in millimeters for 'Inner Clearance' and 'Outer Poke'.
3. Review the 'Fitment Diagram' (if available) that visually represents the shift in wheel position relative to your vehicle's current setup.
4. Review the results to see if you will need spacers or if the wheels will sit too far out, potentially requiring fender modifications for safety.
5. Use the resulting data to ensure your new wheels fit perfectly and safely without the need for expensive trial-and-error in a private environment.
