How to verify for your truck
To confirm the exact lug nut size for your specific wheel setup, follow these steps.
- Check the owner's manual or the door jamb sticker for wheel and lug nut specifications matching your trim level.
- Inspect the current lug nuts on your wheels for any stamped size or pattern numbers on the lug nut head.
- Measure the wheel stud diameter with calipers or a ruler: around 9/16 inch indicates 9/16-18 nuts; around 14 mm suggests M14x1.5 nuts.
- Consult the wheel manufacturer's specifications for the exact lug nut type (60-degree conical seat is common for many wheels).
- If in doubt, contact a Ford dealer or a certified tire shop to confirm the correct lug nut size for your wheel and trim level.
Verifying these details helps ensure proper fitment, safety, and long-term wheel performance.
