What size are the lug nuts on a Toyota Tacoma?

The standard lug nut size for a Toyota Tacoma is 14mm. This is the size of the lug nuts that secure the wheels to the vehicle's hubs. Knowing the correct lug nut size is important for properly maintaining and servicing your Tacoma.


Detailed Information on Tacoma Lug Nut Size


The Toyota Tacoma is a popular mid-size pickup truck that has been in production since 1995. Across the various model years and trim levels, the Tacoma has consistently used 14mm lug nuts to attach the wheels to the vehicle.


This 14mm lug nut size applies to both the front and rear wheels of the Tacoma. It is the same size used on many other Toyota and Lexus vehicles as well. Knowing the correct lug nut size is important when:



  • Changing a flat tire and needing to remove the wheel

  • Rotating the tires to ensure even wear

  • Upgrading to larger or different wheels

  • Performing maintenance or repairs that require wheel removal


Using the wrong size lug nuts can be dangerous, as they may not properly secure the wheel and could lead to the wheel coming loose while driving. It's always best to consult your owner's manual or contact a Toyota dealer to confirm the correct lug nut size for your specific Tacoma model.

What size socket for Toyota lug nuts?


The socket size for most Toyota lug nuts is 21mm or 13/16". However, the 21mm socket is for the inner lug nut, and a 13/16" socket may not fit if the decorative cap has become damaged or swollen. Newer models, such as the 2023 Tacoma, may require a 22mm socket. To confirm the exact size for your vehicle, check the lug nut's specification or use a tire iron or adjustable wrench to measure the nut. 
Recommended socket sizes

  • Standard Toyota: Use a 21mm or 13/16" socket for most standard Toyota vehicles. 
  • Larger Toyota models: Newer models like the 2023 Tacoma may require a 22mm socket. 

How to confirm the size
  • Check specifications: If possible, find the lug nut's specifications or use the vehicle's manual to determine the correct size. 
  • Measure: Use a tire iron or an adjustable wrench to measure the lug nut's size. 
  • Use a tool: Take a lug nut to a hardware store or auto parts store and try it in a socket to find the right fit. 



Is a 13/16 socket the same as 21mm?


No, a 13/16 inch socket is not exactly the same as a 21mm socket, but they are very close and often considered interchangeable, as 13/16 inch is approximately $20.65$mm. Because of the small difference, one size may fit a nut or bolt more snugly than the other depending on manufacturing tolerances. The 13/16" socket often provides a tighter fit on many $21$mm lug nuts. 

  • 13/16" conversion: 13/1613 / 1613/16 inch is equal to approximately 20.6520.6520.65 mm. 
  • 21mm conversion: 212121 mm is equal to approximately 13/1613 / 1613/16 inch, or 0.8270.8270.827 inches. 
  • Practical application: While they are theoretically different, many tools and parts manufacturers list them as equivalent, making them effectively interchangeable in practice. 
  • Best fit: If you have both a 13/16" and a 21mm socket, it is best to try both to see which one fits the fastener most securely without being too loose or too tight. A tighter fit is generally preferred to avoid rounding the fastener head.
