What is a bolt pattern?

Definition: The bolt pattern is the measure between one lughole or lug nuts(top/directly across) and another lug hole aka lug nut (bottom/directly across).

There are many factors to consider before the purchase a new rim or wheel. Bolt pattern is just one of the many factors. If you should find the need to figure out which one will fit your vehicle the best- seek professional advice or guidance. Unless you must  handle this job alone, here is how to figure out the bolt pattern that best suits your vehicle. Refer to our “Parts of a Wheel” post for more details about wheel anatomy. 

The center of this wheel is known as “center bore”. The very distinct holes in the center are known as lugholes. The bolt pattern is the measure between one lughole or lug nuts(top/directly across) and another lug hole aka lug nut (bottom/directly across). Still with me?

Some vehicles can have 4, 5, 6, or 8 lugholes. The animated picture to your left- has 5 lugholes- an uneven number. If this is your case, you must measure the middle of the lug hole from top to the middle section of the part across from it. Refer to the picture on the left, the red line indicated when you should start and end for proper measurement.  If you have even lugholes, measure them directly across from each other.

The diameter of the bolt pattern can be measured in millimeters or inches. If you have any more questions about the matter feel free to contact us with any questions!
