What is the bolt pattern on a Dodge Ram?
In most modern Dodge Ram pickups, the bolt pattern falls into two main families: 5-lug 139.7 mm (5x139.7) for light-duty Ram 1500s, and 8-lug 165.1 mm (8x165.1) for heavy-duty Ram 2500/3500. The exact pattern depends on year, model, and configuration, so verify for your specific vehicle.
Bolt pattern by Ram model
The Ram lineup splits into light-duty and heavy-duty lines, each with typical lug configurations. The patterns below reflect what you’re most likely to encounter on current and recent generations.
Light-duty Ram 1500
Most Ram 1500 pickups built in the 2000s through the 2020s use a 5-lug pattern. The common configuration for many modern 1500s is:
- 5 x 139.7 mm (5x139.7) or 5x5.5 inches
Note: There were some trim or special editions in the past that used different patterns; always verify for your specific year and model.
Heavy-duty Ram 2500/3500
Ram 2500 and 3500 heavy-duty models (including DRW variants) typically use an 8-lug pattern:
- 8 x 165.1 mm (8x165.1) or 8x6.5 inches
Again, verify for your exact year and configuration, as some older specials or regional specs can differ.
How to confirm the bolt pattern on your Ram
To make sure you have the correct wheel fitments for your Dodge Ram, confirm using one or more of these methods:
- Check the owner’s manual or the tire/wheel specification label located on the door jamb or glove box.
- Look at the wheel itself or the factory wheel catalog for the exact lug pattern and center bore.
- Measure directly: count the number of lug nuts (lugs) and measure the diameter of the circle that passes through the centers of the lug holes (lug pattern).
- If in doubt, consult a dealer or a tire/wheel professional with your VIN for model-specific information.
Knowing the exact pattern is crucial before purchasing aftermarket wheels or spacers to avoid fitment issues or safety concerns.
Other fit considerations
Beyond the lug count and spacing, consider the center bore and offset when selecting wheels. The Ram’s standard hub bore and wheel offset can affect fitment and vehicle handling; aftermarket rings or adapters may be needed if the center bore differs.
Summary
For most modern Dodge Ram trucks, the bolt pattern falls into two broad categories: 5-lug 139.7 mm for light-duty Ram 1500s, and 8-lug 165.1 mm for heavy-duty Ram 2500/3500s. Always verify your exact year, model, and trim, because there are exceptions. When changing wheels, check lug count, bolt circle diameter, center bore, and offset to ensure a correct and safe fit.
