The arrangement of lug nuts on a wheel hub, often expressed numerically, is a critical specification for ensuring proper wheel fitment. For the specified vehicle model and year, this measurement dictates the compatibility of aftermarket wheels and the secure mounting of original equipment manufacturer (OEM) wheels. Improper matching of this measurement can lead to wheel instability and potential vehicle damage.
Correct wheel installation, according to this measurement, directly impacts vehicle safety and performance. A precise fit ensures even distribution of stress on the wheel studs, preventing premature wear and potential failure. Historically, this specification has evolved across different vehicle generations to accommodate changes in vehicle weight, braking systems, and overall design requirements, thereby improving road safety.
