What size are Tacoma lugs?
The typical lug nuts on a Toyota Tacoma are M12x1.5 with a 60-degree conical seat, used on a 6x139.7 mm bolt pattern, and they usually require a 21 mm socket. Variations can occur by model year or aftermarket wheels, so always verify for your specific vehicle.
Standard lug size specs on the Toyota Tacoma
These specifications cover the core dimensions you’ll encounter on most North American-spec Tacomas from the mid-2000s onward. If you own a market variant or an outfit with aftermarket wheels, confirm these details for your exact setup.
The following list summarizes the essential dimensions you’re likely to encounter when selecting lug nuts or wheels for a Tacoma:
- Bolt pattern: 6x139.7 mm (6 on 5.5 inches)
- Lug thread size: M12x1.5 (most Tacomas)
- Seat type: 60-degree conical seat (acorn)
- Number of lugs per wheel: 6
- Socket size to tighten: 21 mm
In short, if you own a standard North American-spec Tacoma with OEM wheels, expect six lug nuts on a 6x139.7 mm pattern, M12x1.5 thread, a 60-degree conical seat, and a 21 mm wrench/socket size.
Considerations for aftermarket wheels and variations
When upgrading wheels or using non-OEM hardware, lug sizes and seat types can differ. The following steps help ensure you choose compatible lug nuts and avoid fitment issues:
- Confirm the bolt pattern for the new wheels (6x139.7 mm is standard for Tacomas, but verify).
- Check the thread size and pitch listed for the wheels or lug nuts (M12x1.5 is typical, but some setups may vary).
- Verify the seat type matches your lug nuts or the wheel’s requirements (60-degree conical seats are common for Tacomas).
- Ensure you have the correct socket size (commonly 21 mm for Toyota lug nuts).
- When in doubt, consult the wheel manufacturer or a qualified technician to confirm compatibility.
Following these steps helps ensure you use the correct lug nuts and avoid stripping threads or damaging wheels.
Summary
For most Toyota Tacomas, the standard lug configuration is six lugs per wheel on a 6x139.7 mm bolt pattern, using M12x1.5 threads with a 60-degree conical seat, tightened with a 21 mm socket. Always verify the exact specs for your year, market, and aftermarket wheels, and consult a professional if you’re unsure.
