- Measure the stud diameter and thread pitch with calipers or a thread gauge if markings aren’t legible.
- Contact the wheel manufacturer or a trusted parts retailer with your vehicle year, model, and wheel part number to verify compatibility.
Having the correct lug nut size ensures proper fitting and safe installation. If in doubt, seek guidance from a dealer or professional technician.
