Introduction
In this article, we will delve into the often confusing world of bolt patterns. If you have ever been puzzled by terms like “dual drilled wheel” or wondered why your wheels don’t fit properly, this guide is for you. We will explain the concept of bolt patterns, discuss common misconceptions, and provide step-by-step instructions on how to measure your bolt pattern accurately. By the end of this article, you will be equipped with all the knowledge you need to confidently purchase wheels for your vehicle.
Understanding Bolt Patterns: The Basics
A bolt pattern refers to the configuration of the bolt holes on a wheel, which determines how it attaches to the wheel hub. It is essential to understand your vehicle’s bolt pattern to ensure compatibility when purchasing aftermarket wheels. The most common type of bolt pattern is a single bolt pattern, where all the bolt holes are of the same size and evenly spaced. However, some wheels feature a dual drilled bolt pattern, which allows them to fit multiple vehicle models.
Deciphering Bolt Patterns: Inches vs. Millimeters
One common source of confusion is the use of inches and millimeters to describe bolt patterns. For instance, a Chevy 1500 may have a bolt pattern of “six by five point five” in inches or “six by 139.7” in millimeters. It’s important to note that these measurements refer to the same bolt pattern. Some manufacturers prefer to use inches, while others opt for millimeters. The reasoning behind this discrepancy is often rooted in convenience and ease of understanding.
Dual Drilled Wheels: Two Patterns in One
To reduce manufacturing costs and streamline production, some wheel manufacturers use dual drilled wheels. These wheels have two bolt patterns, allowing them to fit multiple vehicle models. For example, a wheel may have a bolt pattern of “5 on 150” and “5 on 5.5”. This means that the wheel can be used on both Toyota Tacomas and Ram 1500s. By eliminating the need for separate molds, manufacturers save time, money, and minimize the risk of errors.
Measuring Your Bolt Pattern: A Step-by-Step Guide
To determine your vehicle’s bolt pattern accurately, follow these simple steps:
- Identify the number of lugs: Count the number of lugs or bolt holes on your wheel. Common configurations include 4, 5, 6, or 8 lugs.
- Measure the distance: For a single bolt pattern, measure the distance between the center of any bolt hole to the center of the hole directly across from it. This measurement represents the bolt pattern’s second portion in inches or millimeters.
- Determine the dimensions: Convert the second portion of the bolt pattern measurement to the appropriate unit of measurement. For example, if it is in millimeters, convert it to inches (or vice versa).
Uncovering the Mystery of Covered Center Caps
You may have noticed some wheels with covered center caps, while others have exposed lug nuts. The presence or absence of a center cap is often a design choice made by the manufacturer. Most factory wheels come with covered center caps, concealing the lug nuts and creating a sleek appearance. On the other hand, aftermarket wheels, like those from American Force, often feature exposed lug nuts for aesthetic purposes. These wheels are custom-made and forged, allowing for greater customization options.
Can I Use Spike Lug Nuts on my Dual Drilled Wheel?
It is essential to consider the overall appearance when deciding to use spike lug nuts on a dual drilled wheel. While it is technically possible to do so, the result may not look visually appealing. Using spike lug nuts would also expose the unused bolt holes, creating an unbalanced and cluttered appearance. Therefore, it is generally recommended to opt for regular lug nuts for a more clean and cohesive look.
Troubleshooting Fitment Issues
If you encounter fitment issues when mounting your wheels, there are a few steps you can take to troubleshoot the problem. First, ensure that you are using the correct set of holes for your specific bolt pattern. If one set of holes does not work, try the other set. If you continue to experience problems, do not force the wheel onto the hub. Instead, reach out to customer service for assistance. Provide them with the necessary information, such as part numbers and photos, for a more accurate diagnosis and resolution.
Conclusion
Understanding bolt patterns is crucial for anyone looking to upgrade their wheels or replace them with aftermarket options. By grasping the concept of bolt patterns, deciphering inches versus millimeters, and knowing how to measure your bolt pattern accurately, you can make informed decisions when purchasing wheels. Remember, if you ever encounter fitment issues or have any questions, don’t hesitate to seek assistance from a knowledgeable source. Armed with this newfound knowledge, you can confidently explore the world of wheels and enhance the appearance of your vehicle.
