Introduction
In this episode of “I Never Knew,” we will be discussing bolt patterns, a topic that often confuses many people. Whether you are a customer or an enthusiast, understanding bolt patterns is crucial when purchasing wheels and tires. We will explore the different aspects of bolt patterns, such as measurement units, dual drilled wheels, and the significance of center caps. By the end of this article, you will have a clear understanding of bolt patterns and be able to confidently select the right wheels for your vehicle.
Understanding Bolt Patterns
When browsing through wheel options on the Custom Offsets website, you will notice a specific notation next to each wheel. For example, if you own a Chevy 1500, the notation might read “6 by 5.5,” indicating a bolt pattern of six lugs spaced 5.5 inches apart. Additionally, you might see another size, such as “6 by 135,” which signifies a dual drilled wheel.
Dual Drilled Wheels
To save costs and streamline production, wheel manufacturers often create dual drilled wheels. This means that a single wheel can fit two different vehicles. For instance, the wheel mentioned earlier with a bolt pattern of “5 on 150” and “5 on 5.5” can be used on Toyota Tacomas and Ram 1500s. By offering this versatility, manufacturers eliminate the need for multiple part numbers and reduce the chances of mistakes.
Measurement Units
One common misconception when it comes to bolt patterns is the use of different measurement units. Some manufacturers use inches, while others prefer millimeters. For example, a Chevy 1500 might have a bolt pattern of “6 on 5.5” in inches, while the equivalent in millimeters is “6 by 139.7.” It is essential to understand these conversions to avoid confusion. Similarly, Ford uses “6 by 135” as an alternative to “6 by 5.3 inches” for their six-lug pattern.
Measuring Bolt Patterns
To measure a bolt pattern accurately, you need to identify the distance between the lug holes. In the case of a dual drilled wheel, the measurement is done across two sets of holes. For example, a wheel with a bolt pattern of “5 on 5.5” would have a distance of 5.5 inches across the lug holes. Similarly, “5 on 150” corresponds to a 150 millimeter measurement. By understanding these measurements, you can determine the compatibility of a wheel with your vehicle.
Center Caps
Center caps play an essential role in the aesthetics of a wheel. Some wheels have covered center caps, while others expose the lug nuts. Dual drilled wheels often come with covered center caps to maintain a uniform appearance. However, new trendsetters like American Force Wheels have opted for exposed lug nuts for a more rugged look. The choice between covered and exposed center caps depends on the wheel design and manufacturer’s preferences.
Spike Lug Nuts
Spike lug nuts have gained popularity in recent years for their unique appearance. However, not all wheels are suitable for spike lug nuts. For instance, dual-drilled wheels may have additional holes that would be exposed with spike lug nuts, compromising the overall aesthetic. Moreover, custom-made wheels like those from American Force Wheels are forged and designed for specific bolt patterns, limiting the compatibility with spike lug nuts.
Troubleshooting and Conclusion
If you experience fitment issues when mounting your wheels, it is essential not to force them onto the vehicle. Dual drilled wheels might require trying the other set of lug holes for a proper fit. If problems persist, reaching out to customer service can help ensure that you have the correct part number and compatibility information. Custom Offsets is always ready to provide assistance and address any concerns you may have.
By understanding the nuances of bolt patterns, you will have confidence in selecting the right wheels and tires for your vehicle. Whether it’s inches or millimeters, single or dual drilled, and covered or exposed center caps, you now have the knowledge to make informed decisions.
