The arrangement of lug nuts on a vehicle’s wheel hub is a critical specification. This configuration, often expressed as a numerical code (e.g., 5×114.3), dictates the number of studs and the diameter of the circle they form. For a specific luxury crossover SUV model, such as the Infiniti QX50, this measurement ensures proper wheel fitment and secure attachment. An incorrect dimension can lead to wheel instability, damage to the vehicle, or potential safety hazards.
Selecting wheels with the correct specification is paramount for maintaining vehicle performance and safety. A precise match guarantees the wheel is centered correctly on the hub, distributing weight evenly and preventing vibration. Historically, manufacturers have utilized various arrangements, each tailored to the vehicle’s weight, engine output, and intended use. Using the intended arrangement ensures the structural integrity of the wheel mounting system, contributing to a smooth and controlled driving experience. This is often verified by checking manufacturer specifications or online databases before purchasing aftermarket wheels.
