The standard bolt pattern runs from 4 to 8 lugs in most modern automobiles. An indication of a 6-lug design in a circle with a 139.7mm diameter would be a bolt circle of 6139.7. There are various methods for determining a bolt pattern. A measuring tape is usually a practical option, but we suggest utilizing a bolt pattern measuring tool for the most exact measurement. Measure from the center of one wheel stud to the center of the opposing wheel stud if your car has an even number of studs. When measuring a 5-lug vehicle, take your measurement from the center of the closest stud to the outside of the furthest stud.
