The 2015 Altima typically uses M12 x 1.25 lug studs with 19 mm lug nuts, and the recommended torque is about 112 Nm (83 ft-lb). This covers the OEM wheel setup and most factory-equipped wheels.
The question covers thread size, socket size, seat type, and torque, and it’s important to note that aftermarket wheels or different trims can alter these requirements. Always verify with the owner’s manual, service manual, or the wheel manufacturer when changing wheels or lug hardware.
Core specifications for OEM wheels
Before listing the specifications, keep in mind that lug nut sizing can vary with wheel design and aftermarket options. The following are the common OEM specs for the 2013–2018 Altima family:
- Thread size: M12 x 1.25
- Socket size (across flats): 19 mm
- Stud diameter: 12 mm
- Lug nut seat type: 60-degree conical seat (common for Nissan wheel hubs)
- Recommended torque: approximately 112 Nm (83 ft-lb)
Concluding note: These specs cover the standard factory wheels. If you’re using aftermarket wheels, verify compatibility with the wheel manufacturer and ensure the correct seat type and threading are used.
How to verify your exact lug nut requirements
Before relying on a generic size, use these steps to confirm the precise lug nut specifications for your setup, especially if you’ve swapped wheels or added aftermarket rims:
- Check the owner’s manual or service manual for lug nut specs tied to your model year and wheel size
- Inspect the current lug nuts on your vehicle for size, thread markings, and seat type
- Consult the wheel manufacturer or a Nissan dealership if aftermarket wheels are installed
- Measure with a caliper and use a thread gauge if you’re unsure about the threading
Concluding note: Using the wrong lug nut size or torque can lead to wheel distortion, rotor damage, or wheel detachment. Always match your hardware to the wheel and follow recommended torque procedures.
Summary
In short, for a 2015 Nissan Altima with OEM wheels, expect M12 x 1.25 thread with 19 mm lug nuts and a tightening torque near 112 Nm (83 ft-lb). If you’ve changed wheels, verify with the wheel maker or dealership to ensure compatibility and proper torque.
