What size is a Dodge lug nut?
There isn’t a single lug nut size for all Dodges. The correct size depends on your model, year, and wheel setup. In many newer Dodges, lug studs are metric (commonly M12x1.5) and lug nuts are tightened with a 19 mm wrench, though some wheels or older models use different sizes.
Key factors that determine lug nut size
Car makers specify lug nut size based on three things: thread size, seat type, and hex size. Knowing these will help you keep wheels secure and compatible with your vehicle.
- Thread size: Common configurations on Dodge models include metric M12x1.5 and M12x1.25, and some older or specialty vehicles use 1/2"-20 UNF.
- Seat type: Most modern Dodges use a 60-degree conical (tapered) seat; some wheels use an acorn or other seating style requiring a different lug nut.
- Hex size: Typical lug nut wrench sizes are 19 mm or 13/16"; some wheels or aftermarket setups may require other sizes.
Understanding these basics helps you pick the right hardware and avoid damage to threads or wheels. When in doubt, consult the owner’s manual or a Dodge dealership or bring a sample lug nut to a parts retailer for matching.
How to identify your exact lug nut size
To determine the precise lug nut size for your Dodge, follow these practical steps:
- Check the vehicle’s owner’s manual or the manufacturer’s service information for the exact lug nut specifications for your model and wheel option.
- Inspect the current lug nuts on the vehicle. Look for stamped size indicators on the nut itself, or note the hex size and seat type from the nut you remove.
- Measure the thread size on the wheel studs with appropriate tools (thread gauge or caliper). Compare with common sizes: M12x1.5, M12x1.25, or 1/2"-20 UNF.
- Assess the seating: inspect the underside of a nut against the wheel opening to determine if it is a 60-degree conical, acorn, or other seat style.
- When using aftermarket wheels, verify compatibility with the wheel manufacturer’s specs and consider using a matching set of lug nuts designed for that wheel.
Following these steps ensures you get the correct lug nuts tailored to your Dodge’s wheels and brakes, reducing the risk of vibration or wheel loss.
Aftermarket wheels and specialty setups
Note that aftermarket wheels or spacers can alter lug nut requirements. Always confirm the wheel manufacturer’s guidance and use lug nuts that match the seat type, thread, and torque specs recommended for your setup.
Summary
lug nut sizes vary by Dodge model, year, and wheel configuration. The best practice is to verify with the owner’s manual, dealership, or by inspecting the existing lug nuts and studs. Common patterns include metric M12 threads (often M12x1.5) with a 60-degree conical seat and a hex size around 19 mm, but always confirm your exact vehicle’s specifications.
