The 5×120 bolt pattern is a specification for the configuration of lug bolts or studs on a vehicle’s wheel hub. This measurement indicates that the wheel has five equally spaced bolt holes arranged in a circle with a diameter of 120 millimeters. This configuration is crucial for ensuring proper wheel fitment and safe vehicle operation. Incorrect bolt patterns can prevent the wheel from seating correctly on the hub, leading to vibration, damage, and potential wheel detachment.
Adherence to specific bolt patterns is paramount for vehicle safety and performance. The 5×120 specification provides a standardized system, ensuring compatibility between wheels and vehicle hubs across various makes and models. Historically, manufacturers have adopted specific bolt patterns for engineering and design reasons, aiming to optimize wheel strength, weight distribution, and overall vehicle handling. This standardization simplifies wheel selection for consumers, providing a reliable means to match wheels to compatible vehicles.
