The specification detailing the number and spacing of the wheel’s bolt holes on a vehicle is crucial for proper wheel installation and safety. For example, a common configuration for a particular sport utility vehicle includes six evenly spaced holes on a circle with a diameter of 127 millimeters (6x127mm), or approximately 5 inches (6×5″). This measurement dictates which wheels are compatible with the vehicle’s hub. Using wheels with an incorrect specification can lead to loose wheels, damaged studs, and potential accidents.
Adherence to the correct specification ensures that the wheel is securely fastened to the vehicle’s hub. This is paramount for vehicle stability and handling, particularly under demanding driving conditions. Historically, variations in this specification have been common across different vehicle makes and models, reflecting engineering decisions related to vehicle weight, intended use, and structural integrity. Knowing the correct specification prevents the purchase of incompatible wheels, saving time and money while ensuring vehicle safety.
