8x165.1 Bolt Pattern
A bolt pattern, or lug pattern, is a parameter that defines the number of lug holes in the wheel and the diameter of the circle (PCD, Pitch Circle Diameter) that the lug holes form. 8x165.1 bolt pattern, or 8x6.5 when converted to inches, indicates the wheel has 8 lug holes spaced evenly on a circle with a diameter of 165.1 millimeters or 6.5 inches. The 8x165.1 bolt pattern is common to Cadillac, Mercedes-Benz, RAM, Nissan and Ford models.
The 8x165.1 bolt pattern, also known as 8x6.5 inches, is a common wheel fitting specification used by a range of vehicles, particularly heavy-duty trucks and some large SUVs, primarily in the United States market. This specification indicates that the wheel has eight lug holes spaced 165.1 millimeters (or 6.5 inches) across from each other. The designation plays a critical role in ensuring proper wheel alignment, secure mounting, and overall vehicle safety. Vehicles that typically use the 8x165.1 bolt pattern include older models of Chevrolet Silverado, GMC Sierra, Dodge Ram 2500, and 3500, among others. Selecting the correct bolt pattern is crucial when replacing or upgrading wheels, as an incompatible bolt pattern can lead to issues with wheel installation, vehicle handling, and even compromise the structural integrity of the wheels under stress. Therefore, understanding and verifying the correct bolt pattern is essential for vehicle owners and service providers alike to ensure compatibility and maintain optimal vehicle performance and safety.

8-Lug Pattern Torque Sequence
The lug bolt pattern torque sequence is a critical procedure designed to ensure that the wheel is mounted securely and uniformly on the vehicle's hub, preventing potential issues such as wheel vibration or hub damage. This sequence varies slightly depending on the number of lug bolts but always follows a pattern that promotes even distribution of force. When tightening lug nuts or bolts on a wheel with a 8-lug pattern, follow the torque sequence shown below to ensure even and secure tightening. The process usually involves multiple passes: initially tightening bolts to a lower torque setting to seat the wheel properly, followed by final tightening to the manufacturer's recommended torque specification using a calibrated torque wrench. Adhering to this sequence and using the correct torque ensures the wheel is balanced and securely attached, reducing the risk of brake rotor warping and ensuring the safety of the vehicle.
