This specification refers to the configuration of lug studs on the wheel hub of a heavy-duty truck manufactured in 2016, specifically the Ram 3500 model equipped with dual rear wheels. It dictates the number of studs, their diameter, and the diameter of the circle they form, known as the bolt circle. For example, a configuration might be expressed as 8×6.5″, indicating 8 studs positioned on a 6.5-inch diameter circle. Understanding this configuration is critical for ensuring compatibility when replacing wheels or installing aftermarket components.
Correctly identifying this dimension is crucial for safety and proper vehicle operation. Using wheels with an incorrect configuration can lead to wheel detachment, potentially causing accidents and vehicle damage. Historically, heavy-duty trucks have utilized various configurations, and this particular specification represents a standard for the described vehicle model and year, ensuring interchangeability and ease of maintenance. The standardization of this dimension simplifies the process of wheel selection and ensures that replacement parts meet the vehicle’s engineering requirements.
