What size are the lug nuts on a Toyota Highlander?
For most Toyota Highlanders, the lug nuts use a 12 mm diameter thread with a 1.5 mm pitch, and a 21 mm socket is typically used to tighten or remove them. However, exact sizes can vary by model year, trim, and wheel type.
Common lug nut specifications
Here are the most typical specifications you’ll encounter on Highlander models with OEM wheels.
- Thread size: M12 x 1.5 (12 mm diameter, 1.5 mm pitch)
- Lug nut seat type: conical/acorn seating
- Socket size (across flats): 21 mm (most OEM wheels; some aftermarket wheels may require a different size)
- Bolt pattern: 5 × 114.3 mm
- Center bore: 60.1 mm (relevant for wheel fit, not a lug nut size)
- Locking lug nuts: Optional on some trims; requires the special key to remove
In practice, the exact lug nut size you need depends on year and wheel package. Always verify against official specifications or your wheel manufacturer's guidance if you’re using aftermarket components.
How to verify the exact size on your Highlander
Use these steps to confirm the correct lug nut size for your specific vehicle configuration.
- Consult the owner's manual or the door jamb/wheel information label for hardware specifications.
- Identify your model year and trim, then verify the lug nut size (most are M12 x 1.5 with a 21 mm socket).
- If you have aftermarket wheels, check the wheel manufacturer's documentation for the correct lug nut size and seat type.
- If you’re unsure, take an existing lug nut or wheel to a tire shop or Toyota dealership for confirmation.
- Note if your wheels use locking lug nuts and ensure you have the correct key to remove them.
Following these steps will help ensure you have the correct hardware for safe installation and removal. If the size remains unclear, consult a dealer or tire professional for definitive guidance.
Year and wheel variation notes
While the general framework remains constant, some Highlander generations or specific wheel packages may introduce minor variations in lug hardware. The most consistent aspect across generations is the M12 x 1.5 thread with a 21 mm hex for many OEM configurations, but wheel type (steel vs alloy) and aftermarket upgrades can lead to differences. Always confirm with official documentation or a professional if you’re upgrading wheels.
Generation-specific considerations
For buyers and owners, the safest approach is to verify using the VIN, check the dealer’s service catalog for your exact build, or consult the wheel/tires section of Toyota’s official specifications for your year. This ensures you select compatible lug nuts, correct seating, and proper torque values.
Summary
The typical lug nut size on a Toyota Highlander is M12 x 1.5 with a 21 mm socket for most OEM wheels, along with a 5x114.3 mm bolt pattern and a 60.1 mm center bore. However, sizes can vary by year, trim, and wheel type, so always verify against your vehicle’s documentation or with a dealer or tire shop. When upgrading wheels, double-check lug nut size, seat type, and whether locking nuts are present to avoid installation issues.
