What size wrench for Toyota Tundra lug nuts?
The typical lug nuts on Toyota Tundra wheels require a 21 mm socket (about 13/16 inch).
Some wheels or aftermarket setups may use different sizes, such as 19 mm or 22 mm. Always verify by measuring the lug nut flats or checking the wheel’s specification.
Common lug nut sizes you may encounter
Wheels on different trims or aftermarket upgrades can vary. The following sizes cover what you’re likely to see on a Toyota Tundra.
- 21 mm (about 13/16 inch) hex is the standard for most factory lug nuts on Tundra wheels.
- 19 mm (about 3/4 inch) or 22 mm (7/8 inch) hex may appear on some aftermarket wheels or wheels with different seat types. Always verify before forcing a size wrench.
- Use a six-point socket for better grip and to reduce the risk of rounding lug nuts.
Bottom line: If you’re dealing with stock wheels, expect 21 mm; for aftermarket setups, verify with the wheel manufacturer or measure the lug nut flats.
Torque specifications and safety tips
Proper torque ensures lug nuts are snug without overstressing the studs. Here are the guidelines and steps to follow.
- Consult the owner’s manual or the service manual for the exact torque spec for your Tundra and wheel type. A typical range is around 100 ft-lbs (135 Nm), with some configurations listed up to about 110 ft-lbs (149 Nm).
- Loosen lug nuts slightly while the vehicle is on the ground, then lift the vehicle, remove the wheel, and inspect lug studs and seats.
- Install the lug nuts finger-tight, then tighten in a star pattern using a torque wrench set to the specified value.
- Avoid applying anti-seize compound on wheel studs unless the manufacturer specifically instructs you to; this can affect torque readings.
- Retorque after 50-100 miles of driving to account for wheel seating and thread settling.
In short, follow the torque specification for your wheel and use the proper star pattern to ensure even seating.
Notes for aftermarket or unfamiliar wheels
When wheels are replaced or upgraded, lug nut size and torque may change. Always reference the wheel manufacturer’s specification and consider having a professional verify the torque settings.
Summary: For most Toyota Tundra lug nuts, you’ll typically use a 21 mm wrench; verify with your particular wheels. Torque is commonly around 100 ft-lbs, with a star pattern and a recheck after driving; and always consult manuals for exact specs.
