What is the bolt pattern on a Dodge Ram 2500?
The Dodge Ram 2500’s standard bolt pattern is eight lugs on a 6.0-inch bolt circle (8x152.4 mm). Some older or specialty models used an 8x165.1 mm (6.5-inch) bolt circle, so verify for your exact year and trim before buying wheels.
Bolt pattern is the arrangement of wheel lug holes on the hub, defined by how many lugs the wheel has and the diameter of the circle those lug holes form. For Ram heavy-duty pickups, eight lugs are typical, but the bolt circle diameter has changed across generations and configurations, which can affect wheel compatibility with brakes, hubs, and center bore.
Common bolt patterns seen on Dodge Ram 2500
Here are the patterns you’re most likely to encounter on Ram 2500 models. The list highlights the two main patterns and notes when you should double-check for a given year or configuration.
- 8x6.0 inches (8x152.4 mm) — the prevailing pattern on modern Ram 2500 trucks; this is the standard eight-lug arrangement for most models from the 2000s onward.
- 8x6.5 inches (8x165.1 mm) — used on some older Ram heavy-duty models and certain factory wheels; less common in newer years but still seen on certain configurations and aftermarket wheels.
Because bolt patterns can vary by year, trim, and market, always confirm with the door placard or manufacturer documentation for your exact vehicle.
How to verify your bolt pattern
Use these steps to confirm the bolt pattern before purchasing wheels or adapters:
- Check the driver’s door jamb placard or the owner’s manual for the wheel specification, which lists lug pattern, lug size, and center bore.
- Count the number of lug nuts on the wheel hub; Ram 2500 typically uses eight lugs in most configurations.
- Measure the bolt circle diameter by placing a ruler from the center of one lug bolt to the center of the opposite lug bolt across the hub.
- Compare your measurement to the common patterns (8x6.0" or 8x6.5") or consult a parts vendor with your VIN for an exact match.
Verifying bolt pattern helps ensure you don’t buy wheels that won’t fit or require adapters, which can affect safety and performance.
Summary
For Dodge Ram 2500s, the standard eight-lug setup is typically 8x6.0" (8x152.4 mm), with some older models using 8x6.5" (8x165.1 mm). Always confirm the exact pattern for your truck by checking the door placard, manual, or VIN-based specifications before ordering wheels. This simple check ensures proper fitment and safe driving.
