Stud patterns are commonly otherwise known as bolt patterns, bolt circles, lug patterns or PCD’s (pitch circle diameter) – nevertheless, stud patterns are determined by the diameter of a circle which runs through the centers of a wheels stud holes. Oftentimes, there are 4, 5 or 6 stud holes. This diameter determines your stud pattern, in which using the table below, will help provide you important information on your wheel set up such as the stud distance and most commonly used wheel stud size.
“…stud patterns are determined by the diameter of a circle which runs through the centers of the stud holes on a wheel”
When it comes to finding the correct fittings for your axles, it is important to know your required stud pattern to match the wheel pattern. For uneven stud holes such as 5 stud patterns, measure from the center of one stud, to the furthest edge of the most opposite stud. For even stud holes such as 4 or 6 stud patterns, simply measure from the center of one stud, to the center of the opposite stud. Compare your measurements to the stud PCD column in the table below to find your stud pattern.
