When choosing wheels, car owners mostly think about design size and width, but there is another parameter that will be more important for fitting on the car. This parameter named as Bolt Pattern or PCD (Pitch Circle Diameter). In this article we will find out what is Bolt Pattern and how it has affect on Choosing wheels and why this parameter is so important.
PCD (Pitch Circle Diameter) is measurement for distance between circle shaped holes that near center hole that nuts will fits in that. this is so important because this distance is different form car to car. This holes distance should be same as vehicle's detail and this essential for alignment of wheels to vehicle.
Automobile producers after research and engineering will produce each kind of vehicle with special distance between holes and also the mention number of hole depend on the duty, weight, climate and etc. so vehicle can be use with best performance and safety.Â
For every automobile engineers standardize dimension universally that owners can change or customize wheels all over the world easily and also they can get the safety and performance.
The variation of PCD for holes will be start from 3 holes to 10 holes for light weight vehicles to special heavy duty vehicles. Manufacturers design different bolt pattern for different duties and and to merge with the way that vehicle will be use.
Bolt pattern details will be write like "5x150" that the first number that here mentioned 5 is the number of holes that nuts will fit in that and the second number stands for distance between holes. below you can find some details that you can see more

this sizes were metric in this list but also sometime they use imperial you can see like 4x4 or 4x4.25 that because of measurement we use both millimeters and inches, the sizes mentioned as metric in the table all were millimeters. This measurement are globally difference between this two kind of measurement is for compatibility across different countries and regions.
There is a table below that we showed some equal sizes for better understanding.
