What size are the lug nuts on a 2010 Dodge Ram?
The lug nuts on a 2010 Dodge Ram 1500 are typically M14 x 1.5 with a 60-degree conical seating, designed to fit the standard 9/16-inch wheel studs. The common lug nut hex size is around 21–22 mm across flats, though exact size can vary with wheel design and aftermarket parts.
The 2010 Ram 1500 uses a common five-lug pattern, and while the factory wheels share a standard approach, individual wheel choices—especially aftermarket alloys—can change the lug nut size, seating type, or stud dimensions. This article outlines the standard specification, potential variations, and how to verify the exact size for your particular vehicle configuration.
Standard lug nut specification for the 2010 Ram 1500
Below are the typical specs you’ll encounter on stock or commonly paired wheels for this model. These details help ensure proper fitment when replacing lug nuts or installing new wheels.
- Thread size and pitch: M14 x 1.5 (roughly equivalent to 9/16" x 18 in imperial terms).
- Seat type: 60-degree conical (also known as a conical seat) lug nuts.
- Wheel stud size: 9/16"-18
- Nut hex size (across flats): commonly 21 mm or 22 mm, depending on the nut design and wheel type.
These specifications reflect the typical factory setup for many 2010 Ram 1500 configurations, including common alloy and steel wheels. However, different trims or wheel packages can introduce slight variations.
Common variations and aftermarket considerations
Before listing variations, it’s important to note that aftermarket wheels and certain factory options can alter lug nut requirements. The following scenarios are common and worth checking if you’re replacing wheels or lug nuts.
- Aluminum wheels: Usually use conical-seat lug nuts with M14 x 1.5 threads and a hex size around 21–22 mm.
- Steel wheels: Often follow the same thread and seat standards, but confirm the seat type (some early setups used slightly different seats) and the hex size.
- Aftermarket wheels: May require different seat styles (ball seat or mag/bond seats) and can use different thread sizes or hex dimensions; always verify with the wheel manufacturer or installation guide.
In all cases, verify that the lug nuts you purchase match the wheel’s seat type and the vehicle’s stud size. Mismatched lug nuts can lead to improper seating, loose wheels, or safety hazards.
How to verify the exact lug nut size on your Ram
Use these steps to confirm the precise lug nut size for your vehicle and wheels.
- Check the owner's manual or the tire/wheel specification section for lug nut details.
- Inspect the current lug nuts for stamped size (e.g., M14 x 1.5 or 9/16"-18) and seating type.
- Measure the lug nut hex across flats with a wrench or caliper to determine the correct size (common values are around 21–22 mm for M14 nuts).
- When in doubt, contact a Dodge dealership, the wheel manufacturer, or a reputable tire and wheel shop for confirmation.
Verifying the exact size ensures you buy compatible lug nuts for your wheels and avoid installation issues or safety risks.
Summary
For a 2010 Dodge Ram 1500, the typical lug nut specification is M14 x 1.5 thread with a 60-degree conical seat, designed for 9/16"-18 wheel studs, and a hex size commonly around 21–22 mm. Variations can occur with different wheel designs or aftermarket wheels, so always verify the seat type, thread size, and hex dimension for your specific setup by consulting the manual, the wheel manufacturer, or a dealer.
