Is 5×120 the Same as 5×4.5?

The 5×120 bolt pattern is not the same as the 5×4.5 bolt pattern (which is also known as 5×114.3). Here’s the breakdown:

5×120 Bolt Pattern:

• “5” refers to the number of lug holes on the wheel.
• “120” refers to the diameter in millimeters of the circle formed by the centers of the lug holes (bolt circle diameter).

5×4.5 Bolt Pattern (5×114.3):

• “5” refers to the number of lug holes on the wheel.
• “4.5” inches is the diameter of the circle formed by the centers of the lug holes. This measurement in inches converts to 114.3 millimeters.

Key Differences:

• Bolt Circle Diameter: The 5×120 bolt pattern has a diameter of 120 millimeters, while the 5×4.5 bolt pattern (5×114.3) has a diameter of 114.3 millimeters. This difference of 5.7 millimeters makes them incompatible.
• Fitment: Due to this size difference, a wheel with a 5×120 bolt pattern will not fit properly on a vehicle that requires a 5×4.5 (114.3 mm) bolt pattern, and vice versa.

Conclusion:

The 5×120 and 5×4.5 (5×114.3) bolt patterns are not the same and cannot be used interchangeably. It’s essential to ensure that the bolt pattern matches your vehicle’s specifications to ensure proper fitment and safety.
