How to Measure Wheel Bolt Patterns

The bolt pattern or bolt circle is the diameter of an imaginary circle formed by the centers of the wheel lugs.

Bolt patterns can be 4, 5, 6, or 8 lug holes. The diagram indicates the proper measuring methods

 

Four (4) Bolt

Measure center to center of two holes directly across from each other.

Five (5) Bolt



 

Measure from the CENTER on one hole to the BACK of the third hole. This is the easiest and most accurate way to "Estimate" a 5-lug bolt circle. You can also measure from the CENTER of one hole to the CENTER of the third hole using 1.05 multiplier to find your bolt circle.

Six (6) Bolt



 

Measure center to center of two holes directly across from each other.

Eight (8) Bolt


 

Measure center to center of two holes directly across from each other.
