The bolt pattern on Ram 1500 is a crucial specification that affects wheel compatibility. Whether you’re replacing your truck’s wheels, upgrading to an aftermarket set, or simply learning about your vehicle, understanding the bolt pattern is essential. In this guide, we will cover the wheel specifications, compatibility, and important considerations when selecting wheels for your Ram 1500.
What is the Bolt Pattern on Ram 1500?
The bolt pattern on Ram 1500 varies slightly depending on the model year, but most modern Ram 1500 trucks feature a 6×139.7mm (6×5.5 inches) bolt pattern, which means:
- 6: The wheel has six lug nuts that secure it to the hub.
- 139.7mm (5.5 inches): The diameter of the imaginary circle passing through the center of all six lugs is 139.7 millimeters (or 5.5 inches).
Understanding this bolt pattern is essential to ensure proper wheel fitment and compatibility.
Why is the Bolt Pattern Important?
Knowing the bolt pattern on Ram 1500 is crucial for several reasons:
- Ensuring Proper Fitment: The right bolt pattern guarantees that the wheels fit securely.
- Avoiding Safety Issues: Using wheels with the wrong bolt pattern can lead to loose fittings, vibrations, and potential wheel detachment.
- Aftermarket Wheel Compatibility: If you plan on upgrading your wheels, they must match the correct bolt pattern.
- Preventing Handling Problems: Incorrectly fitted wheels can affect handling, leading to unsafe driving conditions.

Besides the bolt pattern on Ram 1500, there are other key wheel specifications to consider:
- Bolt Pattern: 6×139.7mm (6×5.5 inches)
- Center Bore: 77.8mm

These specifications are important when selecting new wheels or tires for your Ram 1500.
Can You Use a Different Bolt Pattern on a Ram 1500?
Some truck owners wonder if they can use a different bolt pattern, such as 5×139.7mm, instead of the 6×139.7mm found on the Ram 1500. The short answer is no, unless you use wheel adapters. Here’s why:
- Different Bolt Patterns Won’t Fit Properly: The lugs won’t align, making it impossible to install the wheels securely.
- Safety Concerns: Improper fitment can lead to stress on the lug bolts, wheel misalignment, and potential failure.
- Wheel Adapters Can Help: If you want to use wheels with a different bolt pattern, hub-centric adapters can convert 6×139.7mm to another pattern, but they should be used with caution.
For the best results, it is always recommended to stick with the factory 6×139.7mm bolt pattern for safety and performance.
How to Measure the Bolt Pattern on a Ram 1500
If you ever need to verify the bolt pattern on Ram 1500, follow these steps:
- Count the Number of Lug Holes: The Ram 1500 has 6 lug nuts.
- Measure the Bolt Circle Diameter: Using a measuring tape or caliper, measure the distance from the center of one lug hole to the farthest point of the opposite lug hole.
- Convert the Measurement to Millimeters: The measurement should be 139.7mm (5.5 inches), confirming the 6×139.7mm bolt pattern.
Choosing the Right Wheels for a Ram 1500
When selecting new wheels, make sure they match the pattern on Ram 1500 and other important specifications like offset and center bore. Here are some tips:
- OEM Wheels: Factory wheels guarantee perfect fitment and performance.
- Aftermarket Wheels: Always check the bolt pattern, offset, and center bore before purchasing.
