The lug nuts on a 2014 Infiniti Q50 are M12 x 1.25 with a 60-degree conical seat, and OEM lug nuts typically require a 19mm socket. The car uses a 5-lug, 114.3 mm bolt pattern. If you have aftermarket wheels, sizes can differ, so verify with your wheel manufacturer or dealer.
Key lug nut specifications you should know
For most 2014 Infiniti Q50 models, the wheel assembly relies on a 5-lug pattern with a 114.3 mm bolt circle. The lug nuts themselves are M12 x 1.25 threaded and have a 60-degree conical seat, which matches the standard OEM wheels and many aftermarket setups. The typical socket size you’ll use to install or remove these lug nuts is 19 mm, though some wheels may specify a different nut design. Always use the lug nuts and seats recommended by Infiniti for your specific wheel package.
How to verify the correct size for your vehicle
To confirm you have the right lug nuts, consult the vehicle’s owner’s manual or the tire/wheel placard on the door jamb, and check with Infiniti if you’re unsure. If you’ve installed aftermarket wheels, verify compatibility with the wheel manufacturer: the thread size, seat type, and bolt pattern must match, and the correct lug nut type should be used. When reinstalling, tighten to the manufacturer’s torque specification and re-torque after a short driving period as advised by tire professionals.
Why this matters for maintenance and safety
Using the wrong lug nut size or seat type can lead to poor wheel seating, uneven torque, and safety risks. Correct pairing of lug nuts to the wheel and hub ensures proper clamping and load distribution. If you’re ever unsure, it’s wise to have a professional verify wheel compatibility and torque settings.
Summary
In summary, the typical lug nut setup for a 2014 Infiniti Q50 is M12 x 1.25 with a 60-degree conical seat, using a 19mm socket, on a 5x114.3 bolt pattern. Always verify with official manuals or wheel manufacturers, especially when using aftermarket wheels, and follow the specified torque for safe installation.
