This specification defines the configuration of the wheel mounting interface for a specific vehicle model. It consists of two key measurements: the number of wheel fasteners (studs or bolts) and the diameter of the circle on which these fasteners are located. For instance, a designation of 5×115 indicates five fasteners arranged on a circle with a diameter of 115 millimeters. This measurement is critical when selecting aftermarket wheels or ensuring proper wheel fitment during vehicle maintenance.
Understanding this vehicle-specific dimension is essential for ensuring wheel compatibility, vehicle safety, and optimal performance. Using wheels with an incorrect specification can lead to vibration, damage to wheel studs, and ultimately, wheel detachment, which can have severe consequences. Moreover, this measurement provides a standardized reference point within the automotive industry, enabling manufacturers and mechanics to select appropriate wheels and tires that meet specific vehicle requirements.
