The specification details the configuration of the wheel mounting studs on the specified vehicle model. It is typically expressed as two numbers: the number of studs and the diameter of the circle on which the studs are arranged (e.g., 5×114.3mm). This measurement is critical when selecting aftermarket wheels, as wheels with an incompatible configuration will not mount correctly or safely. For instance, aftermarket wheel shopping must include confirming compatibility with this measurement.
Adhering to the correct specification ensures proper wheel fitment, which directly impacts vehicle safety and handling. Using incorrectly fitted wheels can lead to wheel detachment, compromised braking performance, and damage to the vehicle’s suspension system. This configuration, a consistent design element throughout many production years, contributes to the vehicle’s overall structural integrity and reliability. Historically, this design parameter reflects a commitment to standardized engineering principles for wheel attachment.
