8x210 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. 8x210 bolt pattern, or 8x8.27 when converted to inches, indicates the wheel has 8 lug holes spaced evenly on a circle with a diameter of 210 millimeters or 8.27 inches. The 8x210 bolt pattern is common to Chevrolet and GMC models.
The 8x210 bolt pattern is a specific wheel lug configuration commonly used on heavy-duty trucks and some commercial vehicles. This pattern denotes eight lug holes spaced evenly around a circle with a diameter of 210 millimeters. The "8" in the designation indicates the number of bolt holes or studs on the wheel hub, while the "210" specifies the distance in millimeters from the center of one bolt hole to the center of the bolt hole directly opposite it. This particular bolt pattern is engineered for vehicles requiring a robust wheel mounting system due to the heavy loads they carry or tow, contributing to the vehicle's stability, safety, and handling. Wheels with an 8x210 bolt pattern must be matched with axles and hubs designed for the same configuration, ensuring a precise fit that can handle the demands of heavy-duty applications. Additionally, this configuration is crucial for maintaining the wheel alignment and balance, critical for the longevity of the tires and the overall drivability of the vehicle.

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.
