The configuration detailing how the wheel’s mounting holes are arranged on a 2018 Toyota Tundra is a critical specification. This measurement, typically expressed with two numbers, defines the number of studs and the diameter of the circle they form. For example, a “5×150” designation indicates five studs positioned on a circle with a 150mm diameter. This specific arrangement is crucial for ensuring correct wheel fitment on the vehicle.
This specification plays a significant role in vehicle safety and performance. Using wheels with an incorrect arrangement can lead to wheel detachment, causing accidents and damage. The original configuration is also vital for maintaining the vehicle’s intended handling characteristics and load-bearing capacity. Historically, this information has been standardized to ensure compatibility within and across vehicle models, allowing for aftermarket wheel options.
