How to Measure Bolt Pattern

The first number in the bolt pattern is the number of bolt holes. The second number is the diameter of the circle the holes sit on. To determine the diameter on wheels with an even number of bolt holes, measure center-to-center on bolt holes directly across from each other on the circle (Example: 8 on 6-1/2 would mean 8 bolt holes with 6-1/2" center-to-center diameter). When the number of bolt holes is odd, measure from the center of any bolt hole to the point halfway between the two bolt holes directly across from it on the circle (Example: 5 on 4-1/2 would mean 5 bolt holes with 4-1/2" measured to a point halfway between the opposite bolts).
