The specification for the 2018 Toyota Tundra’s wheel mounting configuration dictates the number of studs, their spacing, and the diameter of the circle they form. This measurement is crucial for ensuring proper wheel fitment and safe vehicle operation. For instance, if a wheel intended for a different vehicle with a dissimilar configuration is installed, it will not properly seat against the hub, leading to potential wheel detachment and serious accidents.
Correct adherence to this specification is paramount for maintaining vehicle safety, performance, and structural integrity. Historically, this specification has been standardized within the automotive industry to allow for interchangeability and aftermarket wheel options. Using the correct specification ensures that the wheels are properly centered, balanced, and can withstand the stresses of driving, braking, and cornering.
