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. For example, a
bolt circle marked 5x100 indicates a 5-lug pattern with a diameter of 100mm.
4, 6, and 8-lug patterns: Measures the distance between the centers of two holes directly opposite one
5 lug patterns: Measures the distance from the center of one hole to the far side (outside, not center)
of a non-adjacent hole.
The diagram below illustrates the proper measuring methods:
