The arrangement of the mounting holes on a vehicle’s wheel hub, crucial for secure wheel attachment, is characterized by its diameter and the number of bolts or studs it utilizes. This arrangement determines compatibility between a vehicle and its wheels. For instance, a configuration described as 5×114.3 indicates five equally spaced mounting points positioned on a circle with a diameter of 114.3 millimeters. This specification is essential when selecting aftermarket wheels or replacing existing ones.
Understanding this specific arrangement is vital for vehicle safety and performance. Incorrect wheel fitment can lead to wheel detachment, damaging the vehicle and posing a significant safety risk. Furthermore, knowing the exact configuration allows for greater customization options and ensures proper wheel balance and handling. Historically, different vehicle manufacturers have adopted unique configurations, necessitating precise measurement and identification for accurate wheel selection.
