The Ram 1500 rim bolt pattern is an important specification for truck owners looking to replace or upgrade their wheels. Choosing the correct bolt pattern ensures the wheels fit properly, providing safety and optimal performance. In this guide, we will discuss everything you need to know about the Ram 1500 rim pattern, including how to measure it, common sizes, and what to consider when selecting new wheels.
Understanding the Ram 1500 Rim Bolt Pattern
The bolt pattern of a vehicle consists of the number of lug holes and the diameter of the circle they form. It is typically written as 6×139.7, where “6” refers to the number of lugs, and “139.7” represents the diameter in millimeters.
Ram 1500 trucks have used different bolt patterns over the years, so it’s essential to know your specific model’s requirements before purchasing new wheels.
Common Rim Bolt Patterns for Ram 1500
The Ram 1500 rim bolt pattern has varied across different model years. Below are the most common bolt patterns used in Ram 1500 trucks:
- Older Models (1994-2018): Most Ram 1500 models from these years use a 5×139.7mm bolt pattern.
- Newer Models (2019-Present): Many newer Ram 1500 models have switched to a 6×139.7mm bolt pattern, increasing durability and load capacity.
- Heavy-Duty Ram Models: If you own a Ram 2500 or 3500, the bolt pattern is different, often 8×165.1mm or 8x170mm, depending on the model year.
Knowing your truck’s bolt pattern helps ensure proper wheel compatibility and avoids issues with fitment.
How to Measure the Rim Bolt Pattern on a Ram 1500
If you are unsure about your truck’s bolt pattern, you can measure it yourself using the following steps:
- Count the Lug Holes – Ram 1500 trucks typically have either a 5-lug or 6-lug pattern, depending on the model year.
- Measure the Bolt Circle Diameter (BCD) – If the truck has an even number of lugs, measure from the center of one lug to the center of the opposite lug. If the truck has an odd number of lugs, measure from the center of one lug to the imaginary center point between two opposite lugs.
- Confirm the Measurement – Most Ram 1500 models use 5×139.7mm (older models) or 6×139.7mm (newer models).
Choosing the Right Wheels for Ram 1500
When selecting new wheels, ensure they match the Ram 1500 rim bolt pattern. Here are some key factors to consider:
- Bolt Pattern Compatibility – Verify that the wheels have the correct bolt pattern to fit your Ram 1500 without needing adapters.
- Wheel Size – Choose the right diameter and width for proper fitment.
- Offset and Backspacing – Ensure the wheels align properly with your truck’s suspension and fenders.
- Material – Alloy wheels are lightweight and stylish, while steel wheels offer increased durability for off-road and heavy-duty use.
- Tire Fitment – Make sure the new wheels are compatible with your preferred tire size for proper traction and handling.
Upgrading Your Ram 1500 Wheels
If you’re upgrading your Ram 1500’s wheels for better aesthetics, performance, or off-road capability, keep the following in mind:
- Larger wheels can enhance the truck’s stance and aesthetics but may require suspension adjustments.
- All-terrain and mud-terrain tires require wider wheels with proper offset to avoid rubbing.
- Be mindful of load ratings, especially if you use your truck for towing or hauling.

Proper wheel maintenance ensures safety and longevity. Follow these tips to keep your Ram 1500’s wheels in great condition:
- Check lug nuts regularly to ensure they are tightened to the manufacturer’s specifications.
- Clean wheels frequently to remove dirt, road salt, and debris that can cause corrosion.
- Inspect for damage such as cracks, bends, or corrosion that may affect performance.
- Rotate tires according to your Ram 1500’s maintenance schedule to ensure even wear and extended lifespan.
Final Thoughts on Ram 1500 Rim Bolt Pattern
Knowing the correct Ram 1500 rim bolt pattern is crucial when purchasing new wheels, upgrading for performance, or replacing damaged rims. Whether you own an older Ram 1500 with a 5×139.7mm pattern or a newer model with a 6×139.7mm pattern, understanding the specifications ensures a smooth and safe driving experience.
