Understanding Bolt Patterns
A bolt pattern, also known as wheel lug pattern or PCD (Pitch Circle Diameter), specifies the number of lug nuts and the diameter of the circle formed by their centers. This information is essential for ensuring the proper fit of wheels on your vehicle. Getting this wrong can lead to unsafe driving conditions. The bolt pattern is expressed as a number followed by a letter (e.g., 6x5.5"). The number represents the number of lug nuts, and the number after the "x" represents the diameter of the circle in inches.
