Exploring the 5×139.7 Bolt Pattern- A Comprehensive Guide to Understanding This Common Wheel and Tire Configuration

What Bolt Pattern is 5×139 7?

The bolt pattern, also known as the lug pattern or bolt circle, refers to the arrangement of the bolt holes on the wheel rim or hub of a vehicle. It is an essential factor to consider when replacing wheels or tires, as it determines compatibility. One common bolt pattern is 5×139 7, which we will explore in detail in this article.

In the bolt pattern 5×139 7, the first number “5” represents the total number of lug bolts that hold the wheel to the vehicle. This indicates that there are five bolts evenly spaced around the wheel’s circumference. The second number “139” signifies the diameter of the circle that passes through the center of all the bolt holes. This measurement is crucial for ensuring that the wheel will fit properly on the vehicle’s hub.

The final number “7” in the bolt pattern 5×139 7 denotes the bolt circle diameter (BCD) in inches. The BCD is the diameter of the imaginary circle that passes through the centers of the bolt holes. In this case, the BCD is 7 inches, which means the bolt holes are spaced 7 inches apart from each other on the wheel.

Understanding the bolt pattern 5×139 7 is essential for several reasons:

1. Compatibility: When selecting new wheels or tires for your vehicle, it is crucial to ensure that the bolt pattern matches the one specified by the manufacturer. A mismatch in bolt pattern can result in poor wheel fitment, loose lug nuts, and potential damage to the wheel or hub.

2. Wheel Fitment: The bolt pattern determines the size and width of the wheel that can be mounted on the vehicle. In the case of 5×139 7, it allows for a specific range of wheel sizes and widths, ensuring a proper fitment on the vehicle.

3. Tire Fitment: The bolt pattern also influences the tire size that can be mounted on the wheel. A mismatch in bolt pattern can lead to incorrect tire fitment, affecting the vehicle’s handling, stability, and ride quality.

4. Performance: A correct bolt pattern ensures that the wheel and tire assembly is balanced and aligned properly, enhancing the vehicle’s performance and safety.

To summarize, the bolt pattern 5×139 7 is a common configuration used in various vehicles. It is essential to understand its components, including the number of lug bolts, the diameter of the bolt circle, and the bolt circle diameter in inches. By ensuring compatibility and proper fitment, drivers can maintain their vehicle’s performance, safety, and aesthetics.
