The typical lug-nut socket size for a RAM 1500 is 13/16-inch (20.6 mm) hex.
The RAM 1500 uses a five-lug pattern (5x139.7 mm) with conical-seat lug nuts in most factory configurations. However, wheel and nut configurations can vary by year, trim, and aftermarket wheels, so verify the exact size for your rig before work.
Common lug-nut size for RAM 1500
Below is the size most likely to be encountered when servicing RAM 1500 lug nuts.
- 13/16 inch (20.6 mm) hex – the standard size for OEM lug nuts on most RAM 1500 models
In practice, start with a 13/16" socket and only move to other sizes if the 13/16" does not fit snugly or as specified by wheel manufacturer documentation.
What to check with aftermarket wheels
Aftermarket wheels can alter lug-nut size or seating type. Use these steps to confirm the correct socket size for your RAM 1500 and wheel setup.
Seat type and bolt pattern considerations
OEM RAM 1500 lug nuts typically use a conical-seat (60-degree) design on a 5x139.7 mm pattern. Aftermarket wheels may use different seat angles or bolt patterns, so verify both the seat type and the lug-nut size for your exact wheel configuration.
- Check the lug-nuts or wheel documentation that came with the wheels for the specified size and seat type.
- Measure the hex across the flats of the lug nut to confirm the correct size if the documentation is unclear.
- Consult the wheel or lug-nut manufacturer, or your dealership, to confirm the recommended size and torque for your exact year/model and wheel configuration.
Bottom line: aftermarket wheels can require a different lug-nut size or seating type; verify before applying torque to avoid damage.
Summary
For the RAM 1500, a 13/16-inch hex socket covers the majority of factory lug-nut configurations. Always verify against your specific year, trim, and wheel setup, and follow the manufacturer’s torque specifications when reinstalling lug nuts.
