Understanding the 5×139.7 Bolt Pattern- Dimensions and Applications Explained
What is 5×139.7 Bolt Pattern?
The 5×139.7 bolt pattern, also known as the 5×5.5 inch bolt pattern, is a common specification used in the automotive industry to define the spacing of the bolt holes on a wheel’s center bore. This pattern is particularly popular in various vehicle models, including trucks, SUVs, and some passenger cars. Understanding the 5×139.7 bolt pattern is essential for ensuring compatibility between wheels and vehicles, as well as for maintenance and repair purposes.
The “5x” in the 5×139.7 bolt pattern refers to the number of bolt holes on the wheel’s center bore, which is 5 in this case. The “139.7” represents the diameter of the circle formed by the center of each bolt hole, measured in millimeters. This distance is crucial for ensuring that the wheel fits properly on the vehicle’s hub, as an incorrect bolt pattern can lead to alignment issues, vibration, and even potential damage to the wheel or vehicle.
The 5×139.7 bolt pattern is often used in vehicles with larger wheel sizes, as it provides sufficient spacing to accommodate the increased diameter of the wheel. This pattern is commonly found in trucks and SUVs, where the wheel size tends to be larger than that of a typical passenger car. However, it can also be found in some passenger cars, particularly those with high-performance or off-road capabilities.
When it comes to choosing wheels for a vehicle with a 5×139.7 bolt pattern, it is important to ensure that the new wheels have the same bolt pattern. This can be determined by checking the vehicle’s specifications or by consulting the wheel manufacturer. Using wheels with an incompatible bolt pattern can lead to issues such as wheel wobble, poor handling, and potential damage to the wheel mounting hardware.
In addition to ensuring compatibility, the 5×139.7 bolt pattern also plays a role in the overall aesthetics of the vehicle. The spacing of the bolt holes can affect the appearance of the wheel, and choosing the right wheel size and offset can help achieve the desired look. It is important to consider the wheel’s width, offset, and backspacing when selecting new wheels to ensure they are not only compatible with the vehicle but also visually appealing.
In conclusion, the 5×139.7 bolt pattern is a critical specification for ensuring proper wheel fitment and vehicle performance. By understanding this pattern, vehicle owners can make informed decisions when selecting new wheels, ultimately enhancing the appearance and functionality of their vehicles.
