We welcome questions, corrections, and collaboration ideas. Use the details below to get in touch. Please include tire sizes, vehicle model year, and any photos or measurements if you are reporting a fitment finding. For safety reasons we do not provide binding fitment approvals; always confirm with a licensed shop and your vehicle manufacturer.
What to include
- Your current tire size and the size you plan to test.
- Wheel width and offset if relevant.
- Any clearance concerns (suspension, fenders, brakes).
- If reporting data: the source and a screenshot or link.
