The 6×120 bolt pattern is not the same as the 6×5.5 bolt pattern (which is also known as 6×139.7). Here’s how they differ:
6×120 Bolt Pattern:
- “6” refers to the number of lug holes on the wheel.
- “120” millimeters is the diameter of the circle formed by the centers of the lug holes.
6×5.5 Bolt Pattern (Also Known as 6×139.7):
- “6” refers to the number of lug holes on the wheel.
- “5.5” inches is the diameter of the circle formed by the centers of the lug holes. This measurement in inches converts to 139.7 millimeters.
Key Differences:
- Bolt Circle Diameter: The 6×120 bolt pattern has a diameter of 120 millimeters, while the 6×5.5 bolt pattern has a larger diameter of 139.7 millimeters. This difference of 19.7 millimeters makes them incompatible.
- Fitment: Due to this significant size difference, a wheel with a 6×120 bolt pattern will not fit on a vehicle that requires a 6×5.5 (139.7 mm) bolt pattern, and vice versa.
Conclusion:
The 6×120 and 6×5.5 (6×139.7) bolt patterns are distinct and cannot be used interchangeably. Always ensure you use the correct bolt pattern for your vehicle to guarantee proper fitment and safety.
