What size are the wheel bolts on a 2017 Toyota Tundra?
Six lug nuts per wheel with M14x1.5 threads, a 60-degree conical seat, and a 21 mm wrench size, on a 6x139.7 mm bolt pattern.
The 2017 Toyota Tundra uses a six-lug wheel setup. This article breaks down the standard fastener specifications you’re likely to encounter when replacing wheels or lug hardware, and notes what to check if you’re using aftermarket components.
Key wheel fastener specs
These are the core fastener specifications you should confirm when selecting replacement hardware or wheels:
- Wheel lug nut size: M14 x 1.5 (thread diameter and pitch)
- Seat type: 60-degree conical (accommodates standard OE and most aftermarket wheels)
- Hex size: 21 mm across flats (common for OEM lug nuts on this setup)
- Bolt pattern: 6 x 139.7 mm
- Number of lug nuts per wheel: Six
In practice, these specs describe the stock 2017 Tundra wheel configuration. Aftermarket wheels or spacers can alter the required lug hardware, so always verify compatibility with the wheel manufacturer and follow torque specifications from Toyota's service manual.
Additional considerations
Torque values and wheel hardware quality matter for safety. When installing wheels, use the proper torque specification for the lugs as provided in the owner's manual or a service guide, and re-check torque after a short drive to ensure the lugs remain properly tightened.
Summary
The 2017 Toyota Tundra uses six lug nuts per wheel with M14x1.5 threads, a 60-degree conical seat, and a 21 mm wrench size, on a 6x139.7 mm bolt pattern. If you’re swapping wheels, confirm these specs for compatibility and follow the manufacturer’s torque guidelines.
