What is the bolt pattern on a Toyota Tundra 6 lug?
The bolt pattern for a Toyota Tundra with six lugs is 6x139.7 mm (6 on a 5.5-inch bolt circle).
In this article, we explain what that means for wheels, how to verify compatibility, and practical tips for choosing aftermarket rims or replacing wheels on a six-lug Tundra.
Bolt pattern specification
What 6x139.7 means
The 6x139.7 mm specification indicates six lug holes arranged on a circle with a diameter of 139.7 millimeters (approximately 5.5 inches). This pattern is the standard lug arrangement for Toyota Tundra models built with six lugs.
Center bore and hub fit
Most Tundra hubs use a center bore around 106.1 mm. When fitting aftermarket wheels, a hub-centric design or the use of centering rings may be necessary to ensure proper alignment and smooth rotation.
Wheel compatibility considerations
Matching the bolt pattern and more
Wheels must match the 6x139.7 mm bolt pattern to mount correctly. If a wheel is not 6x139.7, it will not fit the hub and studs without adapters, which can affect safety and performance.
Beyond the bolt pattern, verify offset, backspacing, brake clearance, and load rating. Many aftermarket and OEM wheels are available in 6x139.7, but you should confirm all specifications with the wheel manufacturer and a trusted retailer before purchase.
Model year notes
Consistency across generations
From modern Tundra generations onward, the 6x139.7 mm bolt pattern has remained consistent. If you are working with a restoration, conversion, or a legacy model, always double-check the exact spec for your vehicle year and trim with official sources or a dealer to avoid mismatches.
Summary
The Toyota Tundra uses a 6x139.7 mm bolt pattern (6 on 5.5 inches) with a typical center bore around 106.1 mm. This pattern governs wheel compatibility, so when buying wheels or upgrading, confirm the bolt pattern, center bore, offset, and brake clearance to ensure a proper fit. If in doubt, consult the wheel manufacturer or a qualified tire shop for guidance.
