What size socket for 2017 Ram 1500 lug nuts?

The lug nuts on a 2017 Ram 1500 typically require a 13/16 inch (21 mm) socket, but wheel configurations vary. Always verify the exact size on your wheels before attempting a tire change.


Understanding lug nut sizes on the Ram 1500


Ram 1500s from 2017 can wear different wheel setups—from factory steel or alloy wheels to an array of aftermarket rims. The socket size refers to the hex across flats of the lug nut, not the thread size on the stud. While most stock configurations use a 13/16" hex, some aftermarket wheels use a larger 22 mm (7/8") hex or a different seating style, which requires a different socket.


How to confirm the correct socket size


To prevent damage to lug nuts or wheels, confirm the exact size before removing/installing lug nuts. Here are practical steps:



  • Consult the owner’s manual or the wheel manufacturer for lug-nut specifications.

  • Inspect the lug nut on a wheel and measure the distance across the flats with a caliper or ruler to identify the socket size (common values include 21 mm or 13/16").

  • When using aftermarket wheels, check the wheel vendor’s lug-nut requirements for the correct size and seat type.


Conclusion: For most 2017 Ram 1500 setups, a 13/16" (21 mm) socket will fit the lug nuts, but verify for your specific wheel configuration to avoid damage.


Practical tips for wheel work


Always use a properly calibrated torque wrench to re-torque lug nuts to the manufacturer’s specification after wheel installation. If you’re unsure, seek professional assistance to prevent over-tightening or under-tightening.


Summary


In summary, the standard socket size for lug nuts on a 2017 Ram 1500 is typically 13/16 inch (21 mm). Because wheel designs vary, confirm the exact size for your wheels by consulting documentation or measuring the lug nut flats before proceeding.

What size socket is a 2017 Dodge Ram 1500 lug nut?


7/8" hex
14 mm x 1.50 thread size, 7/8" hex.



Is 7/8 socket the same as 22mm?


No, a 7/8 socket is not exactly the same as a 22mm socket, but they are often used interchangeably because the difference is very small. A 7/8 inch socket is equal to 0.8750.8750.875 inches, while a 22mm socket is equal to approximately 0.8660.8660.866 inches, making the 7/8 socket slightly larger. Using a 7/8 socket on a 22mm fastener may feel a bit loose, and a 22mm socket on a 7/8 fastener may be a bit snug. 
Size comparison

  • 7/8 inch socket: 0.8750.8750.875 inches
  • 22mm socket: 0.8660.8660.866 inches 

Interchangeability and potential issues
  • Using a 7/8" socket on a 22mm fastener: This may feel slightly loose because the socket is larger than the fastener. 
  • Using a 22mm socket on a 7/8" fastener: This may be a snug fit, which is generally better than a loose fit, but could be difficult to use. 
  • Recommendation: For the most precise fit, it's best to use the correct tool for the job. If you have a 22mm fastener, use a 22mm socket. If you have a 7/8 inch fastener, use a 7/8 inch socket. 

When to be cautious
  • Corroded or worn fasteners: If a fastener is corroded or the chrome cap has swelled, either socket may fit poorly. 
  • Torque: For high-torque applications, using the correct size socket is important to prevent damage to the tool or the fastener. 



Is 13/16 the same as 21mm?


No, 13/1613 / 1613/16 inch is not the same as $21$mm, but they are very close and often used interchangeably.13/1613 / 1613/16 inch is equal to $20.65$mm, while $21$mm is equal to approximately 0.830.830.83 inches, meaning $21$mm is slightly larger. Because the sizes are so close, a $21$mm socket or wrench will often fit a 13/1613 / 1613/16 inch nut or bolt, and vice versa, though there can be a less-than-perfect fit depending on the manufacturing tolerances of the tools and fasteners. 

  • 13/1613 / 1613/16 inch = $20.65$mm 
  • $21$mm = 0.826770.826770.82677 inches, which is slightly larger than 13/1613 / 1613/16 inch 



What size are the lug nuts on a 1500 Dodge Ram?


The lug nut size for a Ram 1500 is M14x1.5 with a 7/8-inch (or 22mm) hex size for most models from 2013 to the present. Older models may use a different size, such as 9/16-18. It is important to verify the specific size for your vehicle's year to ensure proper fitment.
 
For 2013 and newer Ram 1500 models

  • Thread size: M14x1.5
  • Hex size: 7/8-inch (22mm)
  • Seat type: Conical (Acorn) 

For older Ram 1500 models (prior to 2013) 
  • Thread size: 9/16-18 

Important considerations
  • Verify before purchasing: Always confirm the correct size for your specific vehicle year, as there can be variations. 
  • Match the seat type: Ensure the lug nuts have the correct seat type (e.g., conical/acorn) for your wheels to ensure a proper and secure fit.
