Introduction

In this episode of “I Never Knew,” we’re going to tackle the confusing world of bolt patterns. Many people have questions about bolt patterns, and in this article, we’ll provide a comprehensive rundown to help you better understand this topic. Whether you’re a car enthusiast or a novice, this guide will equip you with the knowledge you need to navigate the world of bolt patterns, specifically for 2012 Chevy 1500 wheels. So let’s dive in!

What is a Bolt Pattern?

A bolt pattern refers to the arrangement of the bolts on a wheel hub. It determines which wheels are compatible with your vehicle. When browsing for wheels on Custom Offsets’ website, you’ll notice a section at the bottom of the page that specifies the bolt pattern. For example, a Chevy 1500 typically has a bolt pattern of six by five and a half inches.

Understanding Dual Drilled Wheels

One common confusion arises when customers see multiple bolt patterns listed for a wheel. This is often the case with dual drilled wheels. Manufacturers use this design to accommodate different vehicles without creating separate molds for each bolt pattern, which would be costly and time-consuming.

For instance, a dual drilled wheel may have a bolt pattern of 5 on 150 and 5 on 5 and a half inches. This means the wheel can fit both Toyota Tacomas and Ram 1500s. It eliminates the need for different part numbers and provides cost savings for manufacturers.

Inches vs. Millimeters: A Matter of Convenience

Another source of confusion is the use of inches and millimeters to denote bolt patterns. While there may not always be a logical reason behind it, manufacturers often use one unit of measurement for convenience. For example, Chevy’s bolt pattern of six on five and a half inches is equivalent to six on one 39.7 millimeters. Ford’s six-lug wheel is represented as six by 135 instead of six by five point three inches.

By using a standardized unit of measurement, manufacturers can streamline the ordering process and avoid unnecessary complications.

Determining the Bolt Pattern

To measure your bolt pattern, you need to identify the distance between the bolt holes accurately. In the case of a dual five-lug wheel, measure the distance from the center of the far right corner to the center of the far across corner. This measurement will give you the second portion of your bolt pattern. For example, a bolt pattern of five on five and a half inches means the distance between the bolt holes is five and a half inches.

Additionally, if you’re measuring the second bolt pattern that includes millimeters, convert the measurement to inches for clarity. For instance, a bolt pattern of five on 150 millimeters would be equivalent to a measurement in inches.

The Role of Center Caps

Center caps play a crucial role in the appearance of a wheel. Some wheels come with covered center caps, while others have exposed lug nuts. The decision to have covered or exposed lug nuts depends on the manufacturing process.

For example, American Force Wheels use exposed lug nuts because their wheels are custom-made and forged per order. This allows for greater customization and eliminates the need for different part numbers. On the other hand, wheels like the ones featured in the video have covered center caps because they are cast wheels poured into molds.

Using Spike Lug Nuts

Spike lug nuts have become popular in recent times due to their unique design. However, it’s important to note that not all wheels are compatible with spike lug nuts. Wheels with a dual drilled bolt pattern, such as the six-lug, five-lug, or eight-lug wheels, won’t look aesthetically pleasing with spike lug nuts. The additional holes would create an unbalanced and cluttered appearance.

Troubleshooting Fitment Issues

If you encounter fitment issues when trying to mount your wheels, it’s essential to troubleshoot before forcing them onto your vehicle. Start by testing the other set of holes if your wheels have a dual drilled bolt pattern. If the fitment issues persist, reach out to the experts at Custom Offsets through email or phone. They can assist you in checking the part number and verifying compatibility.
