What size are the lug nuts on a Lexus NX300?

The Lexus NX300 typically uses M12x1.5 lug nuts with a 19 mm hex socket, on a 5-lug, 114.3 mm bolt pattern. However, exact specs can vary by year, trim, and wheel choice, so always verify for your specific vehicle.


This article explains the standard sizing you’re most likely to encounter, notes potential variations, and shows how to confirm the correct lug nut size and torque for your NX300. Understanding these details helps ensure safe tire mounting and proper wheel fitment.


Standard lug nut specs for the Lexus NX300


Below are the common specifications you’ll see on stock NX300 models and many wheel configurations. Variations may occur with aftermarket wheels or different model years.



  • Bolt pattern: 5 lug, 114.3 mm (4.5 inches) diameter

  • Thread size: M12 x 1.5

  • Lug nut seat type: 60-degree conical (tapered) seat

  • Nut hex size for removal/installation: 19 mm (3/4 inch)

  • Torque specification: typically in the range of 76–100 ft-lb (103–135 Nm); verify with your owner’s manual or door placard


In practice, these values represent the common configuration for NX300 models with stock wheels. If you have aftermarket or non-standard wheels, sizes may differ and should be verified before installation.


Year and wheel variations


Some NX300 trims or optional wheel packages may use slightly different lug hardware. If your car has aftermarket wheels or a non-standard wheel option, confirm the correct lug nut size, seat type, and thread pitch with the wheel manufacturer or a Lexus technician.


How to verify for your vehicle


To confirm the exact lug-nut size and torque for your specific NX300, use these checks:



  • Consult the owner’s manual for wheel and tire specifications

  • Check the door jamb sticker (usually near the driver's door) for wheel information, including bolt pattern and sometimes torque

  • Contact a Lexus dealer or reference the Lexus service manual for your VIN

  • When purchasing aftermarket lug nuts, ensure they match M12 x 1.5, 60-degree conical seat, and 19 mm hex, and fit a 5x114.3 mm bolt pattern


Verifying these details helps prevent damage to studs or wheels and ensures proper torque during installation.


Summary


For most NX300 models, lug nuts are M12 x 1.5 with a 60-degree conical seat, using a 19 mm hex wrench, on a 5x114.3 mm bolt pattern. Always verify your specific year and wheel configuration via the owner’s manual or door placard, and follow OEM torque guidelines to ensure safe and secure installation.
