Is bolt pattern 6×139 7 the same as 6×5 5? This is a common question among vehicle enthusiasts and mechanics alike. Understanding the difference between these two bolt patterns is crucial for ensuring compatibility and proper installation of wheels and tires. In this article, we will delve into the details of these two patterns and compare them to determine if they are indeed the same.
Bolt pattern, also known as lug pattern or bolt circle diameter (BCD), refers to the number of lug holes and the diameter of the circle they form on a wheel. It is an essential factor in determining the compatibility of wheels and tires with a vehicle. The bolt pattern is represented by two numbers, such as 6×139 7 or 6×5 5, where the first number indicates the number of lug holes, and the second number represents the diameter of the circle in millimeters.
In the case of the 6×139 7 bolt pattern, it means there are six lug holes, and the diameter of the circle formed by these holes is 139 millimeters. On the other hand, the 6×5 5 bolt pattern indicates six lug holes with a diameter of 5 inches (approximately 127 millimeters).
Now, let’s address the main question: Are these two bolt patterns the same? The answer is no; they are not the same. Although both patterns have six lug holes, the diameter of the circle formed by these holes is different. This difference in diameter can lead to several issues when trying to fit wheels with one pattern onto a vehicle with the other pattern.
Firstly, the lug nuts required for each pattern may differ in size and torque specifications. Using the wrong lug nuts can result in loose or stripped lug holes, compromising the safety of the wheel and tire assembly.
Secondly, the overall size of the wheel may vary between the two patterns. This can affect the vehicle’s handling, alignment, and even ground clearance. A wheel with a larger diameter than the recommended pattern may cause clearance issues with the suspension or other vehicle components.
Lastly, the spacing between the lug holes may also differ. This can lead to uneven distribution of load on the wheel, potentially causing premature wear and damage to the wheel or tire.
In conclusion, while both the 6×139 7 and 6×5 5 bolt patterns have six lug holes, they are not the same due to the difference in diameter. It is essential to use the correct bolt pattern for your vehicle to ensure safety, proper fitment, and optimal performance. Always consult the vehicle’s manual or a professional mechanic to determine the correct bolt pattern for your specific application.
