Bolt Pattern and Offsets for Cars and Trucks
Bolt Pattern is crucial information you must have before purchasing custom rims for your automobile. The diagram on the left illustrates how bolt patterns are measured. Bolt patterns refer to the distance between your lug nuts. This is very relevant information, due to the fact that when you buy Custom Wheels and Spinning Rims they need to fit your Bolt pattern.
Bolt pattern, lug pattern, PCD, or bolt circle refers to the diameter of an imaginary circle formed by the centers of the lugs on your automobile’s wheel. Bolt patterns may contain 4, 5, 6, 7 or 8 holes or studs.

The image shows how the Bolt Pattern measurement is taken. The bolt pattern consists of two numbers and looks like this (5×4.50) – the first number in this example “5” indicates how many bolt holes or studs are on the vehicle, the other number “4.50” describes the diameter of the circle formed by those “5” holes or studs in either inch or millimeter units (4.50 is inches). Another example: a bolt pattern of 4×100 indicates a pattern with 4 lugs on a circle with a diameter of 100 mm.
A very common bolt pattern is 4 x 114.3 . So in the image that would be 4-Lug and the measurement between the lug studs would be 114.3 millimeters.
Here is a conversion table from inches to millimeters:
