Have you ever wondered what bolt pattern is and why it’s so important when it comes to custom wheels? In this article, we will discuss bolt pattern 101 and provide a comprehensive guide to help you understand this critical aspect of choosing the right wheels for your vehicle. Whether you’re a beginner or an experienced enthusiast, this article is for you. We’ll cover the basics, explain the different measurements used, and provide step-by-step instructions on how to measure your bolt pattern accurately. So, let’s dive in and unlock the mysteries of bolt patterns!
Understanding Bolt Patterns
A bolt pattern refers to the number of bolts or studs on a wheel and the diameter of the imaginary circle they form. It is denoted by two numbers separated by an “x” (e.g., 6x5.5 or 5x150). The first number represents the number of bolts or studs, and the second number represents the diameter of the circle in inches or millimeters. For example, a bolt pattern of 6x5.5 means the wheel has six bolts or studs arranged in a circle with a diameter of 5.5 inches.
Dual Drilled Wheels: Eliminating Part Numbers and Mistakes
One common feature found in many wheels is dual drilling. Manufacturers often make dual drilled wheels to fit multiple vehicle models, saving them time and money. These wheels have two different bolt patterns, allowing them to be used on two different vehicles. For example, a wheel may have a bolt pattern of 5x150 and 5x5.5, which can fit both Toyota Tacomas and Ram 1500s. This eliminates the need for separate part numbers and reduces the risk of ordering the wrong wheels.
Inches vs. Millimeters: The Confusion Unveiled
The measurement of bolt patterns can be given in either inches or millimeters, which can sometimes cause confusion. For example, a Chevy may have a bolt pattern of 6x5.5 in inches, but it may also be listed as 6x139.7 in millimeters. There is often no logical explanation for the difference, but it’s important to be aware of this variation when ordering wheels. Similarly, Ford’s bolt pattern of 6x135 is an easier way to designate the wheel compared to the less intuitive 6x5.3 inches.
Measuring Bolt Patterns: A Simple Process
Measuring your vehicle’s bolt pattern is a straightforward process that requires just a few steps. If you have a wheel with a dual bolt pattern, focus on the first pattern when measuring. In our example of a dual 5-lug wheel (5x150 and 5x5.5), measure the distance from the center of the far right corner to the center of the far across corner. This distance represents the second portion of the bolt pattern. In this case, the measurement would be 5.5 inches. The first portion, 5, indicates five lugs. If you were measuring in millimeters, the second portion would be equivalent to 150 millimeters.
Covered Center Caps vs. Exposed Lug Nuts
When browsing for wheels, you may come across two types: those with covered center caps and others with exposed lug nuts. Covered center caps are more common and provide a cleaner appearance. These caps conceal the lug nuts, giving the wheel a sleek and streamlined look. On the other hand, wheels with exposed lug nuts, like those from American Force, are custom-made and forged, resulting in unique designs. They allow for the use of spike lug nuts, which have become popular in recent years.
Ensuring Proper Fitment: Troubleshooting Tips
If you encounter fitment issues when mounting your wheels, there are a few steps you can take to troubleshoot the problem. First, make sure you have selected the correct bolt pattern and size for your vehicle. If you’re still having issues, try using the other set of holes on the wheel. In the case of dual-drilled wheels, this can often solve the problem. However, if you’re still experiencing fitment problems, don’t force the wheel onto your vehicle. Reach out to the manufacturer or seller for assistance. They can help verify the part number and offer guidance to ensure a proper fit.
Conclusion
Understanding bolt patterns is crucial when it comes to choosing the right wheels for your vehicle. By grasping the basics, knowing the difference between inches and millimeters, and accurately measuring your bolt pattern, you can confidently select wheels that fit perfectly. Whether you opt for dual-drilled wheels or prefer the sleekness of covered center caps, ensuring proper fitment is key. If you have any questions or need further assistance, don’t hesitate to reach out to experts who can offer guidance and support. Now that you’re armed with knowledge, go out there and choose the perfect wheels for your ride!
