The lug nut size on a Honda Odyssey is not identical across every model year. In general, Odysseys use a 5-lug pattern on a 114.3 mm bolt circle with metric M12 x 1.5 threads and conical seating, with a typical 19 mm lug nut hex. Some aftermarket wheels or trims may require a 21 mm hex or have different thread specs, so always verify the exact size for your vehicle via official sources or the wheel documentation.
Key specs you’re likely to encounter
Below are the standard specifications you’ll most often see on Odysseys, useful for selecting replacement lug nuts or when upgrading wheels.
- Bolt pattern: 5 lug holes on a 114.3 mm circle (5x114.3).
- Thread size: M12 x 1.5 (metric).
- Seat type: Conical (tapered) seat, 60-degree standard for most Hondas.
- Hex size (nut size for wrench): Typically 19 mm on OEM wheels; some aftermarket wheels use 21 mm.
- Number of nuts per wheel: 5.
Note: Always confirm with your owner’s manual or door jamb sticker if available, especially if your Odyssey has aftermarket wheels or a replacement wheel set.
Variations by year and wheel choice
While the default specs apply to most stock Odysseys, wheel and trim packages or aftermarket wheels can alter lug nut requirements. If you’ve upgraded to different wheels, check the wheel manufacturer’s lug nut specification or consult a Honda dealer.
Most Odysseys retain the same bolt pattern, but the lug nut seat and size can differ if particularly large brake kits or custom wheels are installed. The safe approach is to verify on your vehicle or with a trusted mechanic.
How to verify your exact lug nut size
To be certain you’re using the correct lug nuts for your specific Odyssey, follow these steps:
- Consult the owner’s manual or the tire/wheel information section for lug nut size and torque specs.
- Check the driver’s door jamb sticker for wheel specs including bolt pattern and lug nut size.
- Identify your wheel type (OEM vs aftermarket) and look up the wheel manufacturer’s lug nut requirements.
- If in doubt, measure the current lug nut across the flats (width across the nut) and count the number of threads on the stud to match a standard M12x1.5 nut.
Once you have the right lug nuts, ensure you torque them to the vehicle’s specification to prevent wheel detachment or damage.
Summary
Most Honda Odysseys use a 5x114.3 bolt pattern with M12 x 1.5 thread and conical seating; the common hex size is 19 mm, though some wheels may require 21 mm. Always verify against your vehicle’s manual, door sticker, or wheel documentation, especially if you’ve installed aftermarket wheels. Accurate sizing and correct torque are essential for safe driving and wheel integrity.
Is 7/8 socket the same as 22mm?
A: 22mm = 0.866", which essentialy is a 7/8" socket. A 7/8" socket will work on a 22mm lug nut, but it can feel a little loose. The other way around, a 22mm can work on a 7/8" lug nut, but it can be really snug, which is not bad.

The 0W-20 designation refers to the oil's viscosity, or its resistance to flow, at different temperatures.
Is a 21mm socket the same as 13/16?
Technically the 13/16 is the smaller and more correct size. Theoretically, both. You can use a 21mm socket on a 13/16 nut. But not vice versa.
