If you would like to determine the bolt pattern of your car or a set of rims, the first thing you need to do is count the number of studs.
If there are 4,6 or 8 studs, simply measure the center to center distance between two studs that are across the hub from each other. That measurement is your bolt pattern diameter.
If you have 5 or 7 studs, you will have to take an extra step to determine the bolt pattern. Just a heads up, you’ll need a calculator for this. First, measure the center to center distance between two studs that are across the hub from each other. If there are 5 studs, multiply the measurement by 1.05 to get the bolt pattern diameter. If there are 7 studs, multiply the measurement by 1.03. Because of the multiplication involved, it’s easier to measure 5 or 7 stud bolt patterns in millimeters.
