The specification defines the configuration of the wheel mounting interface on a 2006 Toyota Tundra. This configuration is characterized by the number of wheel studs, the diameter of the circle on which they are located (bolt circle or pitch circle diameter), and the thread size of the studs. This information is vital when replacing wheels or ensuring compatibility with aftermarket rims.
Correctly matching this specification ensures the safe and secure attachment of the wheel to the vehicle’s hub. Improper fitment can lead to wheel instability, vibration, and potential failure, jeopardizing vehicle safety. The specification is a crucial element in maintaining vehicle performance and structural integrity. Early models may have different lug patterns than later generations of the Tundra; therefore, year-specific information is critical.
