What size are the lug nuts on a 22 Ram 2500?
The lug nuts for a typical 2022 Ram 2500 with factory wheels are 9/16-18 UNC with a 60-degree conical (acorn) seat, used on the common 8x170 mm bolt pattern. If your truck wears aftermarket wheels, sizes can vary, so it’s important to verify with the wheel manufacturer or your dealer.
Typical lug nut size and bolt pattern for factory wheels
Below is the standard specification for most 2022 Ram 2500 models equipped with factory wheels.
- Bolt pattern: 8 on 170 mm (8x170) — the standard eight-lug arrangement on Ram 2500 trucks.
- Thread size: 9/16-18 UNC — lug nut bore threads onto 9/16-inch-diameter wheel studs.
- Seat type: 60-degree conical (acorn) seat — matches the factory wheel hole geometry for proper seating.
- Nut style: conventional lug nuts used with most factory wheels; aftermarket wheels may require different seat types or sizes.
This specification covers the majority of Ram 2500 factory wheels; variations exist for certain trims or aftermarket wheels, so always verify before purchasing replacements.
How to verify the exact lug nut size on your truck
Because wheel configurations can vary across trims and aftermarket setups, use these steps to confirm the correct lug nut size for your specific Ram 2500.
- Check the owner’s manual or the tire/wheel section for lug nut size and torque specs.
- Inspect the current lug nuts for stamped size information on the nut head, if present.
- Measure the wheel stud diameter with a caliper to confirm the correct thread size (e.g., 9/16 inch) and ensure the lug nuts match the studs.
- If you have aftermarket wheels, consult the wheel manufacturer or retailer documentation for the recommended lug nut size and seat type.
- When in doubt, contact your Ram dealer or a trusted tire shop to confirm the exact lug nut size for your configuration.
Conclusion: Verifying through official manuals, wheel documentation, and dealer guidance ensures you use the correct lug nuts and torque, which is essential for safety and wheel integrity.
Common variations and how to handle them
While the 9/16-18 UNC, 60-degree conical seat on an 8x170 pattern covers most Ram 2500 configurations, some aftermarket wheels or special trims may require different lug nuts. If you’re installing aftermarket alloys or wheels from another supplier, confirm the exact lug nut size, seat type, and torque specifications with the wheel manufacturer or your dealer before purchase or installation.
Summary
In most cases, 2022 Ram 2500 trucks with factory eight-lug wheels use 9/16-18 UNC lug nuts with a 60-degree conical seat on an 8x170 mm bolt pattern. Always verify your exact configuration—especially if you have aftermarket wheels or a non-standard trim—by consulting the owner’s manual, wheel documentation, or your dealer.
