Bolt Patterns

When considering custom wheels for a specific application, it is essential that the wheel's bolt pattern matches that of the intended vehicle. The bolt pattern or bolt circle is the diameter of an imaginary circle formed by the centers of the wheel lugs.
The rims bolt circle are 4, 5, 6 and 8 lug patterns.

4, 6, and 8-lug patterns: Measures the distance between the centers of two holes directly opposite one another.

5 lug patterns: Measures the distance from the center of one hole to the far side (outside, not center) of a non-adjacent hole.



Picture show below define how to measure 4, 5, 6, and 8 lugs:












As an aside, the other thing to know is the PCD (Pitch Circle Diameter, ). The PCD is easy to match as this relates to the number of studs you need to hold the wheel on the car. The ACTUAL meaning is the diameter of the studs from the centre of the wheel. Below is the conversion table for PCD.

















Tightening rim is important so that your wheels will have the best equal torque distribution.
