Bolt pattern specifics
For this generation, the standard wheel mounting pattern is eight lugs on a 165.1 mm circle. This applies to most 2003–2009 Ram 2500 and 3500 configurations, including SRW and DRW variants. Always verify by checking an existing wheel or the vehicle’s build data if you are replacing wheels or purchasing adapters.
Common fitment notes for this generation:
- Bolt pattern: 8x165.1 mm (8 on 6.5 inches).

Concluding: The 8x165.1 mm pattern is the key specification to match when sourcing wheels for a 2003–2009 Ram 2500. If you’re replacing wheels, confirm the exact year, model, and DRW/SRW status to avoid fitment issues.
How to verify bolt pattern on your truck
Before buying wheels or adapters, double-check your truck’s bolt pattern in person. This quick check helps you avoid ordering the wrong wheels.
- Inspect an existing wheel: count the lug holes and measure the diameter that passes through the centers of adjacent lug holes (lug circle).
- Verify model year and configuration: use the VIN or owner’s manual; the 8x165.1 mm pattern covers most 2003–2009 Ram 2500/3500 models.
- Consult a wheel specialist or dealer if you are uncertain or dealing with non-standard configurations.
Concluding: Once verified, you can confidently pursue compatible wheels, spacers, or adapters for your Ram 2500.
