What year did GM switch from 8x6 5 to 8x180?

What is a Wheel Bolt Pattern?
The wheel bolt pattern refers to the arrangement and spacing of the lug nuts or bolts that secure the wheels to a vehicle's hubs. The pattern is typically expressed as a number followed by the bolt circle diameter in millimeters. For example, an "8x180" pattern indicates that there are 8 lug nuts or bolts arranged in a circle with a diameter of 180 millimeters.
GM's Transition from 8x6.5 to 8x180
According to the information gathered from various sources, GM switched from the 8x6.5 wheel bolt pattern to the 8x180 pattern in 2007.
The 8x6.5 pattern was a common wheel bolt pattern used on many GM vehicles, particularly trucks and SUVs, prior to 2007. However, the company decided to transition to the 8x180 pattern, which is a larger and more robust design, better suited for the increased weight and towing capacity of modern vehicles.
Reasons for the Change
- Improved strength and durability of the wheel mounting system
- Ability to handle the increased weight and towing capacity of newer truck and SUV models
- Alignment with industry trends and standards for larger, more capable vehicles
- Compatibility with a wider range of aftermarket wheel options
The transition to the 8x180 wheel bolt pattern was a significant change for GM and its customers, as it required the use of new wheels and potentially different lug nuts or bolts. However, the change was necessary to keep up with the evolving demands of the automotive market and ensure the safety and performance of GM's vehicles.
